TURBULENT AIR PENETRATION
Flight through severe turbulence must be avoided, if possible.
If not possible, reduce altitude to increase buffet margin.
The recommended procedures for turbulent air penetration are:
1. AIRSPEED
At or Below 10000 ft ................................................ 200 KIAS
Above 10000 ft ........................................................ 250 KIAS/
0.63 M,
WHICHEVER
IS LOWER
Severe turbulence will cause large and often rapid variations in
indicated airspeed. Do not chase the airspeed.
2. ATTITUDE
Maintain wings level and proper pitch attitude. Use attitude
indicator as the primary instrument. In extreme drafts, large attitude
changes may occur. Do not use sudden large control inputs.
3. PITCH TRIM
Maintain control of the airplane with the elevators. After
establishing the trim setting for penetration speed, do not change
pitch trim.
4. ALTITUDE
Large altitude variations are possible in severe turbulence.
Sacrifice altitude in order to maintain the desired attitude. Do not
chase altitude.
5. THRUST SETTING
Make an initial thrust setting for the target airspeed. Change thrust
setting only in case of extreme airspeed variation.
In case of inadvertent negative-g condition, reduce thrust levers.
NOTE: Do not extend flaps except for approach and landing.
