UPR (LWR) YAW DAMP switches
FAIL ------- OFF |
yaw damper provides turn coordination and dutch roll damping. Operates continuously except autoland, localizer track and flare, and engine out
FAIL - associate channel has failed OFF - channel selected off manually |
|
|
FLAP LIMIT System
A- function B- MANUAL light |
A - active when Speed >175 kts/ Flaps >22 deg, flaps will auto-retract. Flaps return to selected position when speed reduced
B - failure of both channels of the auto flap limit system or selector not in AUTO. manual override available with AUTO/OVRD selector. |
|
|
ELEV FEEL System
A- function B- MANUAL light C - Selector HI/LO |
A - provides simulated feel of aerodynamic loads as a function of airspeed
B - MANUAL - both channels of elev feel system failed or selector not in AUTO C - slews ELF to correspond to an airspeed on the SD config page when system in manual (PULLED) |

LSAS Functions (6)
Longitudinal Stability Augmentation System |
1- Pitch Attitude Hold and Auto Pitch Trim (<30 deg bank to -10 deg pitch) -
holds current attitude by deflecting ailerons up to 5 deg. Stab trimmed for sustained deflection. 2- Pitch Attitude Limiting - keeps pitch <30 deg NU to <10 deg ND 3- Pitch Rate Damping - reduce change of pitch overcontrol (100% avail over 20,000 ft, 30% avail below 16,500 ft 4- Pitch Att Protection and Positive Nose Lowering - PAP takeoff to help prevent tailstrike, PNL landing after spoilers 5- Speed Protection - provide stall or overspeed protection with pitch (A/P OFF, with or without ATS) 6- Stall Protection - at 75-85% of shaker activation, LSAS reduces pitch |
|
|
LSAS OFF when? (4 times)
|
1- Autopilot ON
2- Below 100' RA - except PAP and PNL 3- Bank >30 deg 4- Manual Trim |
|
|
LSAS can be overridden by...
|
> 2 lbs control wheel force - <1500 ft
10-15 lbs force - PAP or PNL active >50 lbs force - Overspeed or stall |
|
|
Parallel Rudder Operation
A- why B - conditions |
A- for thrust asymmetry
B- Autopilot ON Full rudder authority (23 deg) Rudder feedback Bank limited to 10 deg |
|
|
Auto Slat extension when?
|
Outboard slats extend at STICK SHAKER
(inhibited >280/.55M) |
|
|
What are Deflected Ailerons?
|
Ailerons automatically deflected for greater performance
Takeoff - Inboard 11.5 deg - Outboard 15 deg Other times - Inboard 0 deg - Outboard 4 deg |
|
|
The Horizontal Stab is trimmed by:
|
Autopilot
LSAS (1 motor, 1/2 speed) Control Wheel Switches (electric, both motors) Long. Trim Handles (Hydraulic) |
