|
|
On the modified rudder system, what does the STBY RUD ON light mean?
|
It indicates that the standby rudder system is commanded on to pressurize the standby rudder power control unit
|
|
What limits full rudder authority in flight after takeoff and before landing?
|
at speeds above 135kts both hydraulic system A and B pressure are reduced by 25% each
|
|
What happens if the FFM monitor detects opposing pressure?
|
FFM automatically turns on the standby hydraulic pump, opens the standby rudder shutoff valve, and illuminates the STBY RUD ON , MC, AND FLIGHT CONTROL lights
|
|
How are the elevators connected?
|
by a torque tube
|
|
Are the Capts and FOs control wheels connected?
|
yes, by a cable drive system
|
|
What happens if an aileron or spoiler becomes jammed?
|
aileron transfer mechanism allows operating controls to be separated from non operating controls
|
|
Can aileron trim be used during manual reversion?
|
yes
|
|
What condition would illuminate the YAW DAMPER light?
|
B FLT CONTROL switch off or stby rud, or SMYD Computer senses a system fault.
|
|
If hydraulic system B fails, will the yaw damper switch move to OFF automatically?
|
no
|
|
When will the yaw damper switch move to OFF automatically?
|
B FLT CONTROL switch to OFF or STBY RUD
|
|
What is the backup system for operation of the TE FLAPS if B system fails?
|
electrically through the alternate flaps standby position switch
|
|
What happens when you move the ALT FLAPS MASTER switch to arm?
|
-activates the standby pump
-arms the alt flaps position switch -closes the TE flaps bypass valve |
|
What would the illumination of the FEEL DIFF PRESSURE light mean?
|
excessive pressure differential, possibly a failure of one of the hydraulic systems, or a problem with the elevator feel pitot tubes
|
|
What does an illuminated SPEED TRIM FAIL Light mean?
|
failure of both Flight Control Computer channels
|
|
What is the purpose of the Speed trim system? When does it operate?
|
helps return the airplane to a trimmed speed.
-airspeed between 100kts and mach 0.5 -autopilot not engaged -5 seconds after release of trim switches -N1 above 60% -10 seconds after liftoff -sensing of trim requirements |
|
What is the purpose of the Elevator Feel Shift Module?
|
helps prevent further movement into a stall condition by increasing control column force to four times normal feel pressure
|
|
If mach trim system fails, what is your speed restriction?
|
280/ mach 0.82
|
|
What does the mach system trim?

|
yes
|
|
What does the SPEEDBRAKE DO NOT ARM light mean?
|
abnormal condition or test inputs to speedbrake system
|
|
When is the STAB OUT OF TRIM light armed , and what does it mean when illuminated?
|
armed : autopilot engaged
illuminated : autopilot not trimming stabilier properly |
|
What electrical power is needed for the flap position indicator?
|
AC power , transfer bus 2
|
|
What does the illumination of the LE Flaps transit light indicate? indicates more than just LE Flaps movement
|
-Any LED in transit
-Any LED NOT in programmed position -slat skew or asymmetry (inboard 3 only) -during alt flaps ext until reaching TE flaps 10 |
|

|
All LED EXTENDED. (Full ext with flaps 10-40)
|
|
What is indicated by the illumination of the SPEED BRAKES EXT light?
|
-in flight: beyond armed and TE flaps>10 or RA <800ft (undesirable condition!)
-ground: lever in down detent and ground spoilers deployed |
|
Does the speedbrake lever have to be armed to get spoilers on an RTO?
|
no
|
|
Why doesn't speedbrake lever have to be armed during RTO to get spoilers?
|
auto speedbrake system works when :wheels spin up 60kts and rev thrust is selected
|
|
When does the speedbrake system operate on landing
|
-Armed, both throttles to idle,
-flight spoilers deploy, Wheel spin up 60kts -ground spoilers deploy: right main strut compressed RA <10ft if wheel spin up not sensed, flight spoilers deploy on any gear compression. right main gets ground spoilers ) - |
