Flying in Alaska
Introduction
Every pilot knows that flying requires preparation.
The need for a thorough flight plan could not be greater than for a trip to
or across Alaska. The scarcity of roads and facilities, the rough terrain,
and vast distances between communities demand forethought and planning.
Emergency gear, an emergency locator beacon, and an alternate route are
essential if one is to deal with the changing weather conditions and other
circumstances that may arise.
Flight Tips for Pilots in Alaska has
been published for more than a decade in order to help pilots flying to the
state and within it. Use it in addition to the current Alaska Supplement,
Sectional Aeronautical Charts, World Aeronautical Charts (WAC), Airmen's
Information Manual (AIM), current Notices to Airmen (NOTAMs), and current
weather briefings.
The following is a checklist for preparation:
- Always prepare and file a flight plan with
provisions for closing it
- Secure an enroute weather briefing.
- Ask for a list of current Notices to Airmen.
- Check the Common Traffic Advisory Frequency (CTAF)
for each airport and area in which you will be flying.
- Carry current Alaskan navigation charts, the
current Alaska Supplement, and any other information you can obtain about
flying in Alaska.
- Keep in touch by radio. Make position reports over
each Remote Communications Outlet (RCO) you pass.
- If you wish to fly "Off the beaten track", ensure
that you leave detailed information regarding your route of flight with a
Flight Service Station (FSS) or AFSS specialist or responsible person.
Pilot Reports
Please forward pilot reports on significant weather
conditions to the nearest Flight Service Station (FSS). Report the type of
weather you are experiencing, especially if other than forecast. Reports of
ceiling, visibility, turbulence, and icing are valuable. This important
information is passed on to other pilots and to the National Weather Service
for more accurate forecasting. Your report is also included in transcribed
weather broadcasts.
There are numerous airports and strips that are not
maintained on a regular basis. The Alaskan Supplement for these locations
carries a "Caution: Runway condition not monitored, recommend visual
inspection prior to using." If you land at one of these locations, let
us know the conditions so that we may update our information to give to
others. Report, also, if you find the field conditions hazardous or other
than reported to you.
There is no substitute for common sense based upon an
extensive background of local knowledge. The same rules apply here that
prudent pilots have followed for years.
Think out the possible results of any decision or
action.
Keep a good alternate plan of action updated to stay ahead of the weather.
Don't push the weather. The chances are good that it will prove the
forecaster wildly optimistic. Weather in Alaska is very changeable.
When in doubt about a course of action. don't risk it.
General Facts About Alaska
Alaska, the 49th state of the Union, is 365 million
acres in size and has 33,000 miles of coastline. That makes it the largest
state, one with two time zones and seven different climactic regions. The
distances between communities, navigation, and communication points are much
greater than that between points in other states.
The most recent census recorded 606,000 persons living
in Alaska. A majority of these live in and around Anchorage in the
Southcentral region. Fairbanks, in the north, and Juneau, the capital, are
next in size. Juneau is one of the many communities that can be reached only
by air or sea. There are less than 12,000 miles of paved road in the state,
so aviation is the major form of transportation.
There are approximately 600 published airports and
more than 3,000 airstrips in Alaska, many of them are private and are not
maintained on a regular basis. Most of the airports are owned and operated
by the State of Alaska and certified by the Federal Aviation Administration
(FAA).
As you may know, Alaska's northern geographic position
means that it experiences wide variations in the amount of daylight summer
through winter. This can be a factor in planning your flight. Again because
of the size of the state, daylight varies considerably from Southeast to the
North Slope regions. Alaska's landscape varies from lush coastal forests and
high mountain ranges to treeless tundra where the ground has been
permanently frozen for thousands of years.
Climate
Flying conditions in the Alaskan interior and in the
Arctic have been described as good when averaged over the entire year
(Aviation Weather 1982, Alaska Almanac 1993). Although most of the state
experiences good flying weather much of the time, generalizations such as
this fail to describe the potential treachery inherent in some of the
localized, temporary weather conditions and phenomena.
Coastal areas and Arctic slopes are often plagued with
low ceilings, poor visibility and icing. Weather reporting points are often
far apart and adverse weather between stations may go undetected unless
reported by a pilot in flight. Flying conditions are best described in terms
of each of Alaska's distinct climactic zones.
Climate is largely determined by the amount of energy
received from the sun; but local characteristics of the area also influence
climate. Some of the meteorological or oceanographic factors affecting
climate are the length of day and night, the air and water temperatures,
cloud coverage, winds and fronts. The vastness and diversity of the Alaskan
landscape is typically characterized according to four distinct climactic
zones. These are Maritime, Continental, Transition, and Arctic. Generally,
mountain ranges provide the physical separation between the zones by
isolating or modifying the air masses which characterize the climate within
each zone.
The Maritime climactic zone includes the Aleutian
Chain and the Southeast and Southcentral regions of the state. These latter
two regions are home to the majority of Alaska's population. Temperatures
are relatively mild in the winter and cool in the summer. Precipitation is
heavy (50-200" per year), and fall and winter bring frequent storms with
accompanying high winds. Fronts are much more frequent over the coastal
areas than over the interior. Occluded fronts are the rule, and these bring
low clouds, precipitation, poor visibility and sudden fog formations.
Depending upon other conditions, fog may occur as water-droplet fog, ice
fog, steam fog or advection fog. The chief aviation hazards in the maritime
zone change with the seasons. In summer, the main hazard is water-droplet
fog. In winter, ice fog and blowing snow and turbulence associated with
winter storms are the major impediments to aircraft operation. In the spring
and fall, icing and frontal zone turbulence are the major problems, and
advection fog may precipitate and cause icing problems which can be quite
severe.
The Continental climate zone covers the majority of
Alaska. It has extreme temperatures and low precipitation (5-15" per year).
There are fewer clouds in the continental zone than elsewhere, so there is
more warming by the sun during the long days of summer, and more cooling
during the long nights of winter. Precipitation is light because air masses
affecting the area lose most of their moisture crossing the mountains to the
south. In terms of ceiling and visibility, the summer months provide the
best flying weather, although there are more cloudy days in the summer. The
chief aviation hazards in the continental zone are wintertime ice fog and
summertime cloudiness. The scattered cumulus occasionally grow into small
thunderstorms in the summertime. but these can qeneraliv be circumnavigated.
Transitional climactic zones exist along Alaska's
western coast and in the area between the coastal mountains and the Alaska
Range. These climactic zones have wider temperature spreads and less
precipitation than the Maritime climactic zones, but temperatures are less
extreme than those in the continental zone. The major aviation hazard in
these areas is wind, although ice fog and blowing snow are commonplace in
wintertime. Flying conditions are generally worse in mountain passes than at
reporting stations along the route.
The Arctic zone, north of the Brooks Range, has cold
winters, cool summers and a desert-like precipitation (3-7" per year).
Summers are generally cloudy and winters are clear and cold. During the
summer, the top layer of the permafrost melts leaving very moist ground, and
the open water areas increase markedly. Thus, the entire area becomes more
humid, relatively mild, and semi-maritime in character. The largest amount
of cloudiness and precipitation occurs during the summer months. Blowing
snow and strong winds are common hazards in the fall and winter, when winds
blow the fine dry Arctic snows hundreds of feet above the surface.
"Whiteouts" occur when a uniform ceiling overlies a snow or ice-covered
surface and the parallel rays of the sun are reflected and diffused between
these two surfaces. This phenomenon results in a complete loss of the
horizon, shadows, horizontal references, and depth perception. The major
hazards to aviation are the summertime clouds, and the wintertime ice fog,
winds and blowing snow and whiteouts.
Volcanoes (link
to the Alaska Volcano Observatory) on the Aleutian Islands, the Alaska
Peninsula, Alaska Range, and in the Wrangell Mountains are part of the "Ring
of Fire" that surrounds the Pacific Ocean basin. There are more than 80
potentially active volcanoes in Alaska, about half of which have had at
least one eruption since 1760, the date of the earliest recorded eruptions.
Mount Redoubt erupted in both 1968 and 1989, disrupting air traffic due to
the ash cloud. More recently Mount Spurr erupted in June, August and
September, 1992. Anchorage received the brunt of the ash fallout which
halted air traffic out of the city for several days. It was briefly
interrupted again in September 1993. Volcanic eruptions average one to two
per year and significantly affect air transportation every 3 to 4 years.
In order to quantify and rank the aviation weather
conditions at specific locales, a study by the National Center for
Atmospheric Research (NCAR) used the "ZNAT Statistic". ZNAT statistics are
numeric values which are calculated for particular locations, and can be
used for making relative comparisons among particular areas. They are
derived from 12 aviation parameters as follows: Marginal Visual Flight Rule
(MVFR) conditions, Instrument Flight Rule (IFR) conditions, freezing
precipitation, severe weather, volatility, frozen precipitation, rain, wind
gusts, wind speed above 22 knots., obstructions to vision, density altitude
in excess of 2000 feet, and hourly wind change over 20 knots (Glover, 1990).
The Aleutians are generally regarded to have the
world's worst aviation weather and the ZNAT statistic for Cold Bay confirms
that there is no worse aviation weather anywhere. Yakutat, Barrow, Cordova,
Bethel, Nome, Ketchikan, Sitka, lliamna, and Dillingham are also low-lying
coastal areas and have poorer than average weather.
Aviation Services
Flight planning, weather briefings and emergency
services are provided by Flight Service Stations located throughout the
state. There are three Automated Flight Service Stations (AFSS) open 24
hours daily, one each in Juneau, Anchorage and Fairbanks. These facilities
are the hubs for 14 outlying Flight Service Stations. Juneau is the hub
facility for Ketchikan and Sitka. Anchorage is the hub for Palmer, Homer,
lliamna, Dillingham, Cold Bay, McGrath and Talkeetna. Fairbanks is the hub
for Barrow, Deadhorse, Nome and Kotzebue. The hours and season of operation
of the outlying FSS's will vary with the location and staffing, so check
with an AFSS for current information.
There are eight Air Traffic Control Towers (ATCT) in
the state. The FAA staffs control towers at Anchorage International Airport,
Merrill Field in Anchorage, Fairbanks International Airport, Juneau
International Airport, Bethel, Kodiak and Kenai. There is also a control
tower at King Salmon that is not staffed by FAA controllers. Not all towers
operate on a 24 hour basis, so call an AFSS for current information.
Flight Standards District Offices (FSDO) are located
in Juneau, Anchorage and Fairbanks. They provide the flight and air
worthiness inspections for air carriers, air taxis and general aviation
pilots.
Some 400 navigation and communications aids located
across the state are maintained by the Airways Facilities Division of the
FAA. Among the aids available for communication and navigation purposes are:
Remote Communications Outlets (RCO)
Remote Communications Air/Ground Facilities (RCAG)
Instrument Landing Systems (ILS)
VHF Omnidirectional Radio ranges (VOR)
Non-directional Beacons (NDB)
Automated Weather Observation Stations (AWOS)
Visual Flight Rule (VFR) navigation in Alaska depends
primarily upon pilotage due to the distance between navigation aids, low
ceilings and high terrain. It is recommended that you utilize the VFR flight
plan services available in the United States and Canada and make position
reports whenever possible.
Emergency Equipment
Alaska law requires that no pilot may make a flight in
Alaska without carrying emergency equipment.
- This equipment includes:
- Food for each person in the aircraft sufficient to
maintain life for two weeks.
- One ax or hatchet
- One first aid kit
- One pistol, revolver, shotgun, or rifle and
ammunition as appropriate. This is for use in food gathering. protection.
and to attract attention of rescue aircraft or vehicles.
- One small gill net and an assortment of tackle such
as hooks, flies, lines, and sinkers.
- One knife
- Two small boxes of matches
- One mosquito headnet for each person.
- Two small signaling devices, such as colored smoke
bombs, signal mirrors, railroad flares, or Very pistol shells stored in
sealed metal containers.
- In addition, the following are required for winter
travel, October through April.
- One pair snowshoes
- One sleeping bag
- One woolen blanket for each serson
You may be asked about your survival gear when filing
a flight plan, but the responsibility for having it on board the aircraft is
the pilot's. Complete information on survival gear and basic requirements
are contained in the Alaska Supplement under the section "General Notices,
General Information on Flying to Alaska (Civil)".
There is no way to tell an emergency locator beacon (ELT)
test signal from the real thing. If you need to test an ELT, please restrict
it to 3 sweeps during the first five minutes of the hour. If you need to
make a prolonged test, take the beacon to a radio shop where it can be
shielded to avoid undesired emissions.
Pilots should monitor the 121.5 emergency frequency at
all times, but especially after landing to verify the ELT on board the
aircraft has not been accidentally activated.
Flying IFR
For those who choose to fly in and around Alaska under
Instrument Flight Rules (IFR) here are a few pointers to help you have a
safe flight. Alaskan airspace is controlled by one Air Route Traffic Control
Center (ARTCC) located in Anchorage. Communication and radar products are
sent and received at Anchorage Center via satellite, ground, and microwave
transmitters and receivers. As you know, radar and VHF frequencies are based
on "line of sight" reception and transmittal. Because of the mountainous
terrain there are many areas that have marginal to no communications and
many more that have no radar coverage at all. Non-radar rules require you to
make full IFR position reports at all compulsory reporting points. You'll
probably be asked to make more DME position reports than is your custom.
It is also important to monitor your assigned
frequency with extra vigilance. If things get a little too quiet, do a radio
check; you may be out of frequency coverage. If this occurs, become aware of
other frequencies available in the area. This may mean communicating with
the Center via relay through other aircraft, Flight Service Stations, or
through VOR voice feature where available.
Minimum Enroute Altitudes (MEAs) run high in Alaska.
Eight to thirteen thousand-foot MEA's are common throughout the state. In
some areas they can be as high as 23,000 feet. Check your charts carefully
and carry oxygen where necessary. Even in those areas that have established
airways you'll periodically run across an NMEA Gap where NAVAID reception is
limited. You should also be aware that many airways in Alaska are derived
from non-directional beacons (NDBs) Colored Airways (Red, Blue, Green, and
Amber) are still in use. These airways not only serve as primary routes, but
are also used as a "backup" system should a VOR fail.
NDB approaches are common throughout the state and are
used as the only type of approach into many towns and villages. Alaska has
plenty of ILS and VOR approaches, but plan ahead and don't expect vectors to
the ILS final approach course at any more than a hand-full of airports.
Because of limited radar service available in some areas, you may encounter
delays on departure as well as arrival depending on traffic. Non-radar rules
require additional spacing or time sequencing, however delays are normally
minimal.
Give extra heed to NOTAMs and NAVAID outages for the
area into which you'll be flying. A simple NDB outage may not mean much to
many pilots, but consider this. If Clam Cove (CMJ) NDB is out of service at
Ketchikan (KTN), you probably will not be able to make an instrument
approach even though there is a published ILS approach available. The reason
for this is that both the NDB approach and the missed approach procedure for
the ILS require the use of CMJ NDB. If you're not equipped with a GPS, you
can't get into Ketchikan.
A common route into the state will take you from
Whitehorse, Yukon Territory (YXY) to Northway (ORT). If you plan to caravan
to Alaska with a few of your friends, you may find it helpful to space your
departure times out a bit. If you depart YXY as a flight of four and the
weather has unexpectedly gone down by the time you get to ORT, each of you
may have to make a full instrument approach. This could require an
additional 12 to 15 minutes per aircraft. If you are number four in the
flight, you may be in the air an hour longer than you originally
anticipated, and extra fuel may be required.
Alaska has all the services available to pilots that
you find in the "Lower 48" states. Realize that many of our Flight Service
Stations and Towers are open on a part-time basis. When closed and/or
remoted to another location you may be communicating with an AFSS as far as
400 miles away.
A Few Tips on Flying in Canada
As a pilot planning to fly your aircraft in Canada,
you should be well acquainted with the aeronautical facilities and services
available. It is your responsibility to obtain publications and charts
required and to consult the latest "Notices to Airmen" (NOTAM) to ensure
that you have all current information pertinent to the proposed fight. You
should carry on board the Canadian Flight Supplement which updates the
aeronautical charts every 56 days and lists facility frequencies.
This publication contains all the aerodrome/facility
listing and operational information for VFR flight within Canadian airspace,
including radio and emergency equipment. Also listed are communication data,
navigational facilities, radar data, and special notices and procedures.
In the sparsely settled areas, Air Navigation Orders
require your aircraft to be equipped with certain radio and emergency
equipment, the details of which are contained in the Canadian Flight
Supplement.
Flight plans, notifications, and itineraries are
mandatory for all operations over Canadian terrain. You must close a flight
plan, notification, or itinerary upon completion of the flight. The flight
plan in Canada is filed with air traffic control as in the United States.
The flight notification is similar except that it may cover a series of
flights over a period of several days. Search activity is initiated if the
aircraft is not heard from within 24 hours of ETA. A flight itinerary may be
filed in lieu of a plan or notification. The itinerary is filed not with Air
Traffic Control (ATC) but instead with a responsible person. This person
must agree to notify Air Traffic Control or FSS or a law enforcement office
if the pilot fails to check in within 24 hours of an ETA or time specified
by the pilot.
Before every flight you should obtain current weather
reports, including pilot weather reports, forecasts, winds aloft, NOTAM
information concerning status of aids to navigation along the way, and field
conditions at destinations as well as at appropriate alternates.
Uncontrolied VFR flight "on top" or above an overcast is not permitted.

Canada has different laws regarding firearms. You may
not bring a firearm into the country. Check with Customs for current rules.
Clearing Customs
Outward Flights - Advance Notice of Arrival in Canada
Many countries, including Canada, require advance
notice of pilots' intent to arrive in those countries.
Under agreements between the United States and Canada,
operators of private planes may, in most cases, include this advance notice
in item 2 of the remarks section of a flight plan to be filed at the nearest
FAA flight service station prior to departure from the United States. That
station will then transmit the message to the proper authorities in the
country of destination. Contact the nearest FAA flight service station
regarding this procedure.
Aircraft carrying passengers or cargo for hire or
compensation on either the outbound or inbound portions of flights are not
considered to be “private aircraft" other than for Customs reporting
purposes and must comply with the clearance requirements specified for
commercial aircraft as set forth in Part 122, Customs Regulations. Aircraft
leaving the United States for a foreign destination may be subject to a
search by Customs officers.
Inward Flights - Providing Notification to Customs
In order to have an officer present to provide Customs
service for you and your aircraft, Customs must be notified of your
intention to land and the estimated time of your arrival.
This notification may be provided by telephone, radio,
or other means or may be furnished by means of an ADCUS (ADvise CUStoms)
message in the flight plan through the FAA. The term ADCUS should be clearly
identifiable in the “Remark” section of your flight plan if you wish to have
Customs notified. However, this procedure entails the relaying of
information and is not as timely or reliable as direct communication
(telephone, radio, or other means). It is recommended that, if possible,
pilots attempt to communicate directly with Customs by telephone or other
means to insure that an officer will be available at the time requested.
It is the ultimate responsibility of the pilot to ensure that Customs is
properly notified. Failure to do so may subject the pilot to penalty action.
Documentation and Examination on Arrival.
Private aircraft are required to report directly to
Customs for inspection immediately upon arrival. Normally, a Customs officer
(or an officer from the Immigration and Naturalization Service or Department
of Agriculture) will be present if a pilot has given proper advance notice
of arrival. Should no inspecting officer be present, the pilot should
report his arrival to Customs by telephone or most convenient means. He
should keep the aircraft, passengers, crew members, baggage, food, and cargo
intact in a segregated place until the inspecting officer arrives or until
he has received special instructions from a Customs officer.
The pilot should provide the necessary information to
help the inspecting officer prepare the required documentation unless the
pilot has prepared the necessary documents in advance. Customs Form 178 must
be completed for all private aircraft arrivals. This form is obtainable from
Customs.
The pilot must produce for inspection a valid airman’s
certificate (pilots certificate/license), medical certificate, and the
aircraft registration certificate [19 CFR 122.27(c)]. Failure to present the
required documentation could result, in addition to any other applicable
penalties, in civil penalties of $5,000 per violation. Overages, failure to
manifest narcotics or marijuana or any act in connection with such
violations shall be subject to fines as well as seizure and forfeiture of
the aircraft, as provided for under Customs laws 19 U.S.C. 1436 and 1584.
Crew and passenger baggage will be examined in the
same manner as that of other international travelers. A verbal declaration
of articles acquired abroad will suffice, except that a written declaration,
Customs Form 6059B (or appropriate substitute), shall be presented when duty
is to be collected or when the inspecting officer deems a written
declaration necessary. Noncommercial cargo and unaccompanied baggage carried
on board private aircraft shall be accounted for on a baggage declaration CF
6059B), which is to be prepared by the pilot in command, and appropriate
entry for same shall be required. Customs officers will furnish the
necessary forms. In addition, the inspecting officer may require that
baggage and cargo be removed from the aircraft for inspection, and he may
physically inspect the aircraft. It is the responsibility of the pilot to
assist in opening baggage and compartments. Aircraft operators may have to
employ the services of a certified mechanic in the event of extensive
examination.
Registration Certificate Requirements for Border
Crossing
Article 29 of the Convention of International Civil
Aviation requires each aircraft of a member state to carry a Certificate of
Registration when engaged in international air navigation. The PINK COPY of
FM Form 8050-1, which allows aircraft to be used up to 90 days within the
United States, is NOT VALID FOR BORDER CROSSING FLIGHTS. (Reference
FAR 91.203(a)(2) published in September 18, 1989, Federal Register.)
Owners who meet certain requirements may apply to the
FAA Aircraft Registry for a telexed copy of the registration certificate.
This program is designed to minimize hardships for new owners wishing to use
their aircraft in international operations.
- A new owner should send a copy of:
- the aircraft registration application
- the bill of sale
- a five-dollar check or money order payable to the
U.S. Treasurer
- a cover letter explaining why the copy is needed
- The cover letter must include
- the date on which the international flight is
anticipated
- a telephone number for purposes of billing the
telex
- the owners signature
The telex copy will be issued after confirmation of
the application information and determination of eligibility. The telex copy
may then be carried as a temporary registration certificate, pending receipt
of the actual document.

Aviation Safety Program in Alaska
The Aviation Safety Program isn't a new concept. In
fact, it has been in existence for more than three decades throughout the
United States. It is based on the premise that accidents can be reduced
through pilot education in the form of seminars and individual counseling.
There are three Flight Standard District Field Offices
Alaska. Each office has a Safety Program Manager (SPM) who is dedicated to
pilot safety education within the district. Each SPM is a fully qualified
Aviation Safety Inspector. In addition to seminars and clinics, these
individuals also review accident/ incident reports to identify airmen
deficiencies, participate in accident investigations, and promote Pilot
Proficiency Programs. They learn from studying accidents so they can help
pilots guard against behaviors that contribute to accidents. The SPM's work
closely with other FAA divisions, such as Air Traffic and Aviation Medical,
and with industry groups to develop aviation safety materials and programs.
The SPM is also responsible for identifying and resolving safety problems
noted during routine surveillance and maintaining a lending library of
aviation safety materials available to the public free of charge.
Another part of this program involves dedicated
volunteers who are available to answer pilot questions and concerns. These
Safety Program Counselors (SPCs) are appointed yearly by FAA managers. They
are highly respected, active pilots, mechanics, or air traffic controllers
located in communities throughout the nation who agree to provide their time
and expertise to help other pilots.
In Alaska, there are presently more than 100 SPC's
that support the program by providing advice and safety information to their
fellow airmen. They assist with seminars and clinics to promote flight
safety.
Whether you are new to flying in Alaska or are a
sourdough, the program has something to offer everyone. Aviation safety is a
continual educational process. Contact your local Safety Program Manager for
further information on seminars and a list of Safety Program Counselors in
your community. |
