|
High lift devices power |
TE flaps, LE flaps (i/b engine), LE slats (o/b engine) - pwrd by hydraulic system B If system B fails - Alt flaps switch - TE flaps operate electrically (ext/ret) - LE devices use standby hyd system - Extend only |
|
|
Primary flight controls pwr |
Pwrd hydraulically Backup pwr - Ailerons & elevator - cable system - Rudder - standby hydraulic system |
|
|
LOW PRESSURE (overhead) |
= low pressure to primary flight controls - ext when standby rudder selected |
|
|
Aileron/Spoiler jam |
- apply force to cw to identify which system has fault - if aileron system jammed, force to FOs cw provides roll control from spoilers (capts cw inop) - if FOs cw jammed, force to capts cw provides roll control from ailerons (FOs cw inop) |
|
|
Speedbrake Auto on landing |
- both ground and flight spoilers deploy to destroy lift and inc braking efficiency Conditions - lever armed - SPEED BRAKE ARMED (green light) - RA < 6' - landing gear strut compressed - both thrust levers idle - mains spin up > 60kts |
|
|
Speedbrake lever DOWN, Auto on landing/RTO |
- reverse thrust levers to reverse thrust pos - thrust levers to IDLE - mains spin up > 60kts |
|
|
To retract spoiler panels after landing/RTO |
- advance either thrust lever OR - Speedbrake lever to DOWN |
|
|
Elevator jam |
- if 1 cc jams, both apply force against jam - will brake out 1 cc which is used for elevator control (higher force req) If jam in aft elevator control mechanism - both cc limited range - elevator jam landing assist system uses spoilers to inc/dec RoD during app/land |
|
|
FEEL DIFF PRESS (overhead) |
Elevator feel and centering unit simulates aerodynamic forces, sends to cc - bases on a/s from elevator pitot system and stab pos
Amber light = excessive differential press in computer - when either hydraulic system or elevator feel pitot system fails |
|
|
Trim |
- flaps extend = electric trim in high speed - flaps retract = electric trim in low speed STAB OUT OF TRIM (blw lights test) = A/P not trimming stab properly |
|
|
SPEED TRIM FAIL + MC (FLT CONT) |
System returns a/c to trimmed speed by commanding stab in direction opposite speed change - in man flight (TO, climb, GA) |
|
|
STBY RUD ON + MC (FLT CONT) |
standby rudder activated, system A or B input jammed or disconnect
Auto: force flight monitor detects opposing press btwn A & B actuators Man: through FLT CONTROL switch |
|
|
YAW DAMPER (overhead) |
- disengaged
If amber light + auto switch to OFF = fault in system - must select STBY RUD before switch can be reset ON
YD - Dutch roll prevention, Gust dampening, turn coordination - inputs may be overriden by pedals or trim |
|
|
LE devices |
TE 1-25 = LE to full extend, slats to extend TE > 25 = LE & slats to full extend
Panel: Amber = in transit /uncommanded pos Ext = retracted |
|
|
System protection |
FSEU - protects against excessive air loads on TE flaps (relief for pos 10-40)
Autoslat system - high AoA, slats auto full extend
PFD Green number - flap maneuvering speed
Bottom amber bar - flap limit placard speed for next normal flap setting |
|
|
Flight Control lights |
LOW PRESSURE = hydraulic press to ailerons, elevators, and rudder low SPOILERS = one or more spoiler pairs inop |
|
|
Aileron trim limitation |
Do notnuse when autopilot engaged |
|
|
Max alt with flaps extended |
20,000 feet |
|
|
Speedbrake limitations |
Flaps 40 - Do not extend beyond ARMED Do not deploy at RA 1000'or less |
