Airplane Systems Flashcards
Engine Fail Msg (less than command performance)
RED- thrust less than command and speed below 65 k and 6 k prior to V1
Caution ENG FAIL (L,R)-engine decelerates to less than Idle speed.
תעלם אם המנוע יתאושש או ב fuel control cut off
ENG THRUST
- actual thrust significantly less than command thrust,or
- actual thrust is not increasing to command thrust, and
-airspeed is V1-6 k or grater
APU Automatic Start
In flight if Both AC Transfer busses lose power
Center Hyd components
Flight cont
Leading edge
Trailing edge flaps
Landing gear
Alternate brakes
Nose gear steering
Main gear steering
RAT
*Provides hyd only to the flight control connected to center hyd sys.
* provides hyd end Elec through the flight.
Deploy automatically:
-both Engines failed and Center sys pressure is low ,or
-both AC transfer buses unpowered,or
-all 3 Hyd sys pressure are low.
**the hot battery or app battery must be powered
TAC thrust asymmetry compensation
- if thrust level on one engine differs by 10% from other engine, automatically adds rudder.- Before Liftoff TAC uses less rudder to help pilot recognize engine failure, after Liftoff fully compensate
TAC Available except:
* speed below 70 k on ground
* reverse applied, or
*loss of engine data or sys malfunction
** TAC May disengage following severe damage or surge
Wheel to rudder Cross-Tie
Provides capability to control the initial effect of Engine failure using control wheel inputs only.
It can deflect the rudder up to 8 degrees. And below 210k in normal mode
Flight Control Modes
- primary
- secondary
-Direct
Flaps Control Modes
-Primary (Hyd)
-Secondary (electric)
-Alternate (electric)
TOGA in the ground
-Below 50k activate THR REF (thrust limit page).
If not pushed below 50k- no operation of A/T until 400’
-if pushed above 80k: disarms LNAV/VNAV, & automatically show FD’s if off
TOGA in flight TAKE OFF
- removes T/O & Climb derates &assumed
-A/T in THR REF mode
-disarm LNAV/VNAV
-50’-400’sect TOGA Roll mode
-above 400’ selects TOGA roll & pitch
TOGA in flight Approach
(Flaps not up or GS capture)
-activate AT in THR mode with GA reference. Thrust adjust to provide 2000 rpm climb
-select TOGA roll & Pitch modes
-arms LNAV
-disarm AFDS modes
-inhibits during landing from 2 feet for 3 sec or more, if Landing is cancel TOGA available again above 5 feet.
Engine start procedure
(Oil pressure)
-if no oil pressure indication by EGT rise, do ABORTED START ckexklist
#oil temp must be >-40 for start and 50 c before advancing thrust to take off power
