MOUNTAIN FLYING IN THE SIERRA'S AND SURVIVING
IT! |
Mr. Hart Drobish, Aviation Safety Counselor, CFI-IM of Courtney Aviation,
Columbia,Ca. will be speaking this May 7th about his techniques and safety
issues concerning his flights while over the Sierra's. His presentation
is hard hitting and informative. One that all aviators need to hear time
and time again. Most mountain airports in the state of California are paved
and properly maintained. Popular mountain airports such as Columbia, Mariposa,
Mammoth, Pine Mountain Lake and Kernville have improved facilities including
an FBO with fuel services. However, other fields in the mountains are not
often used, need special arrangements in order to acquire fuel and/or transportation
to town.
Planning that fun-filled fishing trip up to Idaho's back country? Pilots
flying into remote airstrips must remember that most of these locations
have few, if any, support facilities. Resources such as aircraft maintenance,
fuel, telephone, courtesy cars, lodging, food, rest rooms, and tie down
chains will not be available. Most of these airstrips are unattended and
receive little or no maintenance. It is highly recommended that pilots obtain
the current runway condition from the airstrip owner or manager before using
these airstrips.
MOUNTAIN FLYING TIPS
(Source: State of Idaho's Airport Facility Directory) |
Prior to flying into the back country, consider the following information
on mountain flying.
GENERAL
- Do not consider flying the mountain country until you are proficient
in slow flight. A check-out by an experienced mountain flying instructor
is highly recommended
- Before flying into mountainous areas, practice short field landings
power-on, upwind, downwind and crosswind. Be sure you can land on a fifty
foot spot every time.
- Carry enough fuel to make a complete round trip plus fifty percent.
Know your aircraft. Do not take an aircraft into mountain terrain that
will not takeoff and land in a minimum distance. Most airports in this
area are substandard in length and width and have an associated high density
altitude.
- Keep your aircraft weight as light as possible.
- Know your planned destination airport. Check with experienced mountain
pilots, if possible. Know the altitude, length, condition and approach/departure
procedure at the airport. Many of these fields are one- way, and on some,
a go-around is not possible once you have committed to land.
- Check the weather frequently and stay out of doubtful or bad weather.
Mountain weather changes rapidly and unexpectedly.
- Plan your flight to arrive in the early morning hours. As a rule- the
air begins to deteriorate around 10:00 a.m., grows steadily worse until
about 4:00 p.m., then gradually improves until dark.
- Stay out of the mountains if the wind is over 25 knots.
- Route your trip over valleys whenever possible and study your charts
thoroughly.
- Maintain a minimum of 2000' AGL while overflying the back country.
- Approach all ridges at an angle so that you can turn away if you encounter
a downdraft. After crossing the ridge, head directly away from it.
- Expect the wind to be changing constantly in the mountains. If you
are unable to gain altitude on one side of the canyon, try the other side.
If there is no improvement there, fly the center. But do not, under any
circumstance fly up a canyon or valley without sufficient altitude and
room to turn around. The grade of the canyon may climb faster than your
aircraft.
- Maintain flying speed in downdrafts. Do not panic; air does not go
through the ground. A ground cushion of air will always be there unless
below the top of the timber. The stronger the downdraft, the greater velocity
it will have when it changes direction.
- Remember you will not have a horizon to check your aircraft attitude
once you begin a let down in the mountains. Watch your airspeed and cross
check your instruments.
- Caution: traffic pattern terrain clearance is not standard at many
mountain airports.
- Above all, FLY THE AIRCRAFT EVERY SECOND, DON'T LET IT "FLY
YOU." YOU CANNOT MAKE MISTAKES.
- Do not fly an aircraft that does not have a ceiling sufficient to get
you above the mountains without help from the updrafts.
- Be sure to leave your itinerary with someone. You may be landing on
airports where there is no one to help you in case of trouble, and it is
a long walk out. Do not take chances.
- Equip yourself with proper clothing and at least minimum survival equipment
on any flight into the mountainous areas. Make sure your ELT is in good
working condition.
LANDINGS
- Safety of flight dictates that each pilot transmit in-the-blind on
122.9 whenever approaching or departing a non-unicom equipped airport so
as to advise other aircraft of your intentions.
- You cannot maintain visual contact with the runway at many of the back
country airports. This situation will make it mandatory that you know the
location and intentions of all other airport traffic.
- Terrain and runway gradient usually dictates landing upstream. However,
there are exceptions. Consult the airport directory for the preferred landing
pattern. Maintain the recommended approach speed with power (see pilot's
operating handbook). If the aircraft is settling too fast, add power, but
do not make power-off approaches. When the landing is assured, reduce power
for a controlled sink rate to the runway. Retract the flaps immediately
after contact to increase braking effectiveness.
- If you have doubt about any approach, go around while you are still
high and have room to maneuver safely.
- Do not maneuver to land at low altitudes. Go far enough from the field
to turn so pattern execution can be made at a safe altitude. If you find
turbulent air when you let down in the canyons, return home. Turbulent
air has no respect for you, regardless of your experience or ability. After
landing, park your aircraft well clear of the usable runway surface.
- Check ELT on 121.5 MHZ before leaving aircraft.
-
TAKEOFFS
- Remember that each thousand feet you are above sea level decreases
aircraft performance. Temperature increases density altitude so a 5000'
airport elevation can be well above 8000' density altitude on a hot day.
You should compute your takeoff roll using your aircraft operations manual
and other published guidelines. Also, compute your rate-of-climb to ensure
you can maintain terrain clearance. If in doubt, do not take off.
- Use common sense on takeoffs. If the air is turbulent, weather is marginal,
or you have a tail wind, wait until conditions improve. Let the aircraft
use as much runway as it needs, then it will be flying when it leaves the
ground. Do not pull the aircraft off until you have gained proper flying
speed.
- You can shorten the takeoff distance by making your turn at the end
of the runway at a good fast taxi speed, open the throttle as the aircraft
swings around to line up with the runway. Practice the maneuver with an
instructor on a good standard airport
ATTENTION PILOTS OF AMATEUR-BUILT
AIR CRAFT |
|
It has been brought to our attention that some district pilots of home-builts
have been desirous to show off their "fighter-pilot" skills after
chowing down at one of our local airport restaurants. Be advised that taking
off midfield at ANY airport is potentially hazardous to your health,
not to mention your beautifully built airplane. Additionally, turning maneuvers
after takeoff in excess to 60 deg's is considered aerobatic and subject
to enforcement action. So be smart and fly smart (& safe).
