25
nombre de mode Aileron PCU
* Normal * bypass * blocking/damped
26
Normale mode PCU Aileron
en mode normale , l ACE energise ## Footnote _en dessous de la vitesse de croisiere_ **_l_**es solenoid by pass et blocking _au dessus de la vitesse de croisiere_ de energise le blocking solenoid
27
mode by pass PCU aileron
28
mode blocking PCU aileron
29
au sol les pcu aileron sont calibré en mode ?
Blocking/damped utiliser le manuelle by pass pour deplacer l aileron dans la direction du haut
30
Flaperon PCU mode
* Normal * by pass au sol sasn hydraulic , on est en by pass
31
by pass mode flaperon pcu
32
quel est le mode du flaperon au roulage
bypass
33
SARD
Spoiler Auxilliary retract devices
34
quels sont les spoilers qui sont manoeuvrer par cable
4 et 11
35
role Wheel damper
absorber les vibrations de control du volant
36
role du wheel force transducer
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
role du aileron high speed droop
augmenter le lift de 2° diminuer la conso carburant
38
aileron lockout
a vitesse de croisiere , les ailerons s ajuste a la suface de l aile et se verouille
39
les spoiler 4 et 11 sont limités a
45°
40
role des insulator
les insulators aide a proteger l avion des courant electrique causé par la foudre
41
spoiler 4 et 11 role cable jaune role cable
cable jaune pour le speedbrake cable pour le roulis
42
role du sard
le sard retracte automatiquement les spoiler 7 et 8 quand les tobogans sortent
43
role du spoiler mixing fonction
la fonction melange spoiler PFC combine la commande de roulis et de speedbrakeen une commande pour chaque spoiler controlé electriquement
44
SARD dispo dans quel mode?
tous les modes
45
raison lockout spoiler 5 et 10 a haute vitesse et haute altitude
to prevent tail buffet at cruise speed, spoilers 5 and 10 fair to the wing surface and lock out during cruise.
46
differente utilisation auto speedbrake
* RTO * Aterrissage * sorti au max spoiler
47
auto speedbrake uniquement en mode ?
Normale
48
combien de PCU dans la rudder
3 PCU pour chaque source hydraulique et donc 3 ACEs
49
TAC
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
Rudder ratio
During flight, the rudder ratio function reduces the movement of the rudder as the airspeed increases
51
different mode PCU rudder
* normale * bypass 1 PCU fail * damped 2 ou 3 PCU fail
52
au sol la rudder est en mode?
damped
53
hydraulic pressure controle ( rudder PCU )
2 modes full pressure ( aterrissage et decollage ) reduced pressure ( cruise )
54
rudder position transducer ?
4
55
combien de backdrive sur la rudder
2 backdrive
56
friction brake
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.
