*Flight Controls-Flaps/Slats Flashcards
What system prevents Flap or Slat asymmetry?
WTB-Wing Tip Brakes
How many Slat/Flap Control Computers (SFCC) are installed?
What would occur if one SFCC failed?
-2
-The slats and flaps would continue to operate but at 1/2 speed.
With only the Green hyd system pressure available, will both the flaps and slats operate?
Yes, at a slower speed.
What causes the WTB to operate? (ROAM)
Runaway (move handle to 1, all go to 3)
Overspeed (flap jack screw brakes)
Asymmetry (both on one side, move farther)
Movement (Never touch the handle, ALL just move)
If the WTB activates due to FLAP asymmetry can the SLATS still operate?
Yes, ONLY flap operation is inhibited.
What would occur if one SFCC failed?
Slats and Flaps would continue to operate, but at half speed.
What flap/slat configuration correspond to position 1 on the FLAPS lever and how do they differ?
CONF 1+F is used for takeoff and provides both slats and flaps
CONF 1 is used in flight and is slats only.
When will the Automatic Retraction System (ARS) operate?
During acceleration in CONF 1+F, the FLAPS (not slats) will automatically retract to 0 at 210 kts.
What is Alpha Lock?
This function inhibits retracting the slats from 1 to 0, at a high angle of attack or low airspeed.
When the FLAP legend appears on the ECAM in blue, what is indicated?
Flaps/Slats in transit.
What happens to the ailerons when the flaps are extended?
They droop 5 degrees.
