ATTENUATOR UNLOCKED (LH AND/OR RH ATTENUATOR UNLOCK ADVISORY LIGHT ON)
Indicates that the respective thrust attenuator is not in the stowed (locked) position. Normal if the attenuator switch is in AUTO and throttles are at idle on the ground.
ON THE GROUND, THROTTLE NOT AT IDLE
1. Correct condition prior to flight or REFER to DISPATCH WITH ATTENUATOR STOWED procedure.
IN FLIGHT
1. Thrust Attenuator Switch - STOW.
PRIOR TO LANDING
2. Multiply the landing distance in Figure 4-40 by 1.05.
3. Reduce the maximum landing weight in Figure 4-39 by 50 pounds if landing with a tailwind and/or downhill runway gradient.
4. Seats, Seat Belts and Shoulder Harnesses - SECURE.
5. Avionics and Flight Instruments - CHECK.
6. Radar Altimeter - SET.
7. Passenger Advisory Lights - PASS SAFETY.
8. Passenger Seats - CHECK FULL UPRIGHT and OUTBOARD.
9. Flaps - TAKEOFF AND APPROACH.
10. Engine Synchronizer - OFF.
11. Fuel Transfer - OFF.
12. Ignition - ON.
13. Antiskid - CHECK ON.
14. Landing Gear - DOWN and LOCKED.
15. Flaps - LAND.
16. Landing Lights - ON.
17. Airspeed - VREF.
18. Autopilot and Yaw Damper - OFF.
19. Annunciator Panel - CHECK.
20. Pressurization - CHECK ZERO DIFFERENTIAL.
21. Speed brakes - RETRACTED PRIOR TO 50 FEET.
22. Crew Briefing - COMPLETE.
IF ATTENUATOR DOES NOT STOW
2. Use caution during approach. Thrust attenuator will deploy at low thrust settings and blow back at higher thrust.
