Flaps/Slats Flashcards
With only Green hydraulic system pressure available, will both the flaps and slats operate?
Yes, at ½ speed
What system prevents flap or slat asymmetry?
Wing Tip Brakes (WTB)
What causes the WTBs to activate (ROAM)?
Runaway (Move handle to 1, all go to 3)
Overspeed (Flap jack screw breaks)
Asymmetry (Both on one side move farther)
Movement (Never touch handle, ALL just move)
If the WTB activates due to a flap asymmetry can the slats still operate?
Yes, only flap operation is inhibited
How may Slat/Flap Control Computers (SFCC) are installed?
2
What would occur if one SFCC failed?
The slats and flaps would continue to operate, but at half speed
What flap/slat configurations correspond to position 1 on the FLAPS lever and how do they differ?
CONF 1+F is used for takeoff and provides both slats (position 1) + 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 knots
What is Alpha Lock?
This function inhibits retracting slats from 1 to 0 at a high angle of attack or low airspeed
When the FLAP legend appears in cyan on the upper ECAM display what is indicated?
Flaps/slats in transit
What happens to the ailerons when the flaps are extended?
The ailerons droop 5˚
