(1) Airspeed is critical for any type of turbulent air penetration. Use the
Airplane Flight Manual recommended turbulence penetration target
speed (170 IAS) or, if unknown, airspeed below maneuvering speed.
Use of high airspeeds can result in structural damage and injury to
passengers and crewmembers. Severe gusts may cause large and
rapid variations in indicated airspeed. Do not chase airspeed.
(2) Penetration should be at an altitude that provides adequate
maneuvering margins in case severe turbulence is encountered to
avoid the potential for catastrophic upset.
(3) If severe turbulence is penetrated with the autopilot on, the altitude
hold mode should be turned off. If the autopilot has an attitude hold
mode, it should be engaged. The autopilot attitude hold mode can
usually maintain attitude more successfully than a pilot under stress.
(5) Keep wings level and maintain the desired pitch attitude and
approximate heading. Use smooth, moderate control movements to
resist changes in attitude. If large attitude changes occur, avoid
abrupt or large control inputs. Avoid, as much as possible, use of the
stabilizer trim in controlling pitch attitudes. Do not chase altitude.
