25
Q

nombre de mode Aileron PCU

A
  • Normal
  • bypass
  • blocking/damped
26
Q

Normale mode PCU Aileron

A

en mode normale , l ACE energise

en dessous de la vitesse de croisiere

les solenoid by pass et blocking

au dessus de la vitesse de croisiere

de energise le blocking solenoid

27

28
Q

mode blocking PCU aileron

A
29
Q

au sol les pcu aileron sont calibré en mode ?

A

Blocking/damped

utiliser le manuelle by pass pour deplacer l aileron dans la direction du haut

30
Q

Flaperon PCU mode

A
  • Normal
  • by pass

au sol sasn hydraulic , on est en by pass

31
Q

by pass mode flaperon pcu

A
32
Q

quel est le mode du flaperon au roulage

A

bypass

33
Q

SARD

A

Spoiler Auxilliary retract devices

34
Q

quels sont les spoilers qui sont manoeuvrer par cable

A

4 et 11

35
Q

role Wheel damper

A

absorber les vibrations de control du volant

36
Q

role du wheel force transducer

A

le wheel force transducer mesure la force totale provenant du wheels controle du captain et du FO.le wheel force transducer envoi un signal analogique electrique aux ACE. les PFC utilise ces signaux pour la fonction protection du Bank angle protection

37
Q

role du aileron high speed droop

A

augmenter le lift de 2°

diminuer la conso carburant

38
Q

aileron lockout

A

a vitesse de croisiere , les ailerons s ajuste a la suface de l aile et se verouille

39
Q

les spoiler 4 et 11 sont limités a

A

45°

40
Q

role des insulator

A

les insulators aide a proteger l avion des courant electrique causé par la foudre

41
Q

spoiler 4 et 11

role cable jaune

role cable

A

cable jaune pour le speedbrake

cable pour le roulis

42
Q

role du sard

A

le sard retracte automatiquement les spoiler 7 et 8 quand les tobogans sortent

43
Q

role du spoiler mixing fonction

A

la fonction melange spoiler PFC combine la commande de roulis et de speedbrakeen une commande pour chaque spoiler controlé electriquement

44
Q

SARD dispo dans quel mode?

A

tous les modes

45
Q

raison lockout spoiler 5 et 10 a haute vitesse et haute altitude

A

to prevent tail buffet at cruise speed, spoilers 5 and 10 fair to the wing surface and lock out during cruise.

46
Q

differente utilisation auto speedbrake

A
  • RTO
  • Aterrissage
  • sorti au max spoiler
47
Q

auto speedbrake uniquement en mode ?

A

Normale

48
Q

combien de PCU dans la rudder

A

3 PCU pour chaque source hydraulique et donc 3 ACEs

49
Q

TAC

A

Thrust assymmetry compensationThe thrust asymmetry compensation (TAC) helps control the airplane during asymmetrical engine thrust conditions. The TAC protection function operates in the PFCS normal mode only.

50
Q

Rudder ratio

A

During flight, the rudder ratio function reduces the movement of the rudder as the airspeed increases

51
Q

different mode PCU rudder

A
  • normale
  • bypass 1 PCU fail
  • damped 2 ou 3 PCU fail
52
Q

au sol la rudder est en mode?

A

damped

53
Q

hydraulic pressure controle ( rudder PCU )

A

2 modes

full pressure ( aterrissage et decollage )

reduced pressure ( cruise )

54
Q

rudder position transducer ?

A

4

55
Q

combien de backdrive sur la rudder

A

2 backdrive

56
Q

friction brake

A

The friction brake supplies a resistive force to the movement of the rudder pedal forward controls. This resistive force is equivalent to the typical resistance of a cable-controlled system.
