AUTOPILOT
If Autopilot On
1. Use of the basic autopilot Attitude and Heading hold modes is recommended.
2. Avoid use of Flight Director vertical modes.
3. Pilot inputs should be made through the turn and pitch controller, if installed.
4. Avoid using Touch Control Steering in severe turbulence.
5. Severe conditions may cause the autopilot to disengage.
If Autopilot Off Or Disengaged
1. Hand flying the airplane again requires basic attitude control.
2. Pitch and roll attitudes may best be controlled with the control yoke only.
3. Use of rudder is not recommended and may actually aggravate the situation.
YAW DAMPER
1. The Yaw Damper should be engaged at all times. DO NOT FLY INTO AREAS OF
KNOWN SEVERE TURBULENCE WITH A FAILED YAW DAMPER.
If in turbulence with Yaw Damper off, avoid chasing airplane motion with rudder. Attempt to
hold rudder pedals stationary and wings level.

BIRD INGESTION
If both engines flameout, an immediate relight is recommended. As RPM is decreasing, perform
the following procedures immediately:
1. Power Levers..................................................................................................................... IDLE
2. Airstart Ignition.................................................................................................................... ON
3. Altitude/Airspeed...................................................................................Descend at 210 KCAS
If at low altitude and unable to achieve immediate relight:
Prepare for Dual Engine Out Landing Procedure. Refer to EMERGENCY PROCEDURES
Section 4.
NOTE: Use of Speed brakes is not recommended. Use of the Standby Electrical System
(ABEX) Generator is not possible with a windmilling engine.
CAUTION: MANEUVERS SHOULD BE LIMITED TO MINIMUM BANK AND PITCH
ANGLES NECESSARY SINCE HYDRAULIC BOOST WILL BE LOST AS
ENGINE RPM DECAYS.
CAUTION: FOR AIRPLANES SN 1000 THRU 1249 WITHOUT ASC 304: THE DUTY
CYCLE TIME FOR CONTINUOUS (AIRSTART) IGNITION WITHOUT ASC
304 IS FIVE (5) MINUTES ON AND THIRTY (30) MINUTES OFF FOR
COOLING THERE IS NO LIMITATION ON THE IGNITION WHEN USED IN
A THIRTY (30) SECONDS ON, THIRTY (30) SECONDS OFF CYCLE.
FOR AIRPLANES SN 1250 AND SUBS AND SN 1000 THRU 1249 WITH
ASC 304: THERE IS NO DUTY CYCLE TIME LIMITATION FOR
CONTINUOUS (AIRSTART) IGNITION WITH ASC 304.
CAUTION: ENGINE DAMAGE MAY RESULT IF RPM IS NOT ALLOWED TO
STABILIZE AT IDLE BEFORE ADVANCING POWER LEVERS.
If engine(s) DO NOT relight, continue descent to the Airstart envelope (Sea Level to 25,000 ft.
and 200 KCAS to 324 KCAS). Proceed to the nearest suitable landing site.
Refer to Dual Engine Flameout Procedure, Emergency Procedures Section 4.
