2. Airstart Ignition (L / R AIR START IGN) .....................................ON
3. Altitude / Airspeed ....... DESCEND AT 270 KCAS / 0.75 MT UNTIL
OUT OF TURBULENCE, THEN DESCEND AT VMO/MMO TO
25,000 FEET
NOTE: Use of speed brakes is not recommended. Use of the Standby
Electrical Power System (ABEX) generator is not possible with a
windmilling engine.
CAUTION: MANEUVERS SHOULD BE LIMITED TO THE MINIMUM
NECESSARY BANK AND PITCH ANGLES, SINCE HYDRAULIC
BOOST WILL BE LOST AS RPM DECAYS.
CAUTION: FOR AIRPLANES SN 1000 THROUGH 1249 WITHOUT
ASC 304: THE DUTY CYCLE 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.

CAUTION: FOR AIRPLANES SN 1250 AND SUBSEQUENT, AND
SN 1000 THROUGH 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:
1. Descent To Airstart Envelope .......................................CONTINUE
(Sea Level to 25,000 ft and 200 KCAS to 324 KCAS)
2. Airplane ..... PROCEED TO NEAREST SUITABLE LANDING SITE
3. Dual Engine Flameout Procedure (Page EC-3)............. CONSULT
Airspeed Parameters:
1. Recommended turbulence penetration airspeed is 270 KCAS /
0.75 MT, whichever is lower.
2. A minimum speed of 1.5 VS is recommended to maintain
adequate buffet margins.
3. Severe turbulence will cause large and often rapid variations in
indicated airspeed.
CAUTION: DO NOT CHASE AIRSPEED.
Attitude Parameters:
1. Maintain the desired pitch attitude and keep wings level.
2. Large and sudden control and power changes should be avoided.
Passenger Warning:
1. ST BELT and/or NO SMOK/ST BELT Switch ............................ ON
If Autopilot is 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 using 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 is 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:
WARNING: DO NOT FLY INTO AREAS OF KNOWN SEVERE
TURBULENCE WITH A FAILED YAW DAMPER.
1. The yaw damper should be engaged at all times.
2. If in turbulence with yaw damper inoperative or disengaged, avoid
chasing airplane motion with rudder. Attempt to hold rudder
pedals stationary and wings level.

Bird Ingestion AFM APP E
If both engines flame out, an immediate relight is recommended.
As engine RPM is decreasing, perform the following steps
IMMEDIATELY:
1. Power Levers............................................................................IDLE
2. Airstart Ignition (L / R AIR START IGN) .....................................ON
3. Altitude / Airspeed .................................. DESCEND AT 210 KCAS
If at low altitude and unable to achieve immediate relight, prepare for a
dual engine out landing. See Engines Index, page EC-1, for
procedures as appropriate.
NOTE: Use of speed brakes is not recommended. Use of the Standby
Electrical Power System (ABEX) generator is not possible with a
windmilling engine.
CAUTION: MANEUVERS SHOULD BE LIMITED TO THE MINIMUM
NECESSARY BANK AND PITCH ANGLES, SINCE HYDRAULIC
BOOST WILL BE LOST AS RPM DECAYS.
