Flashcards in FLAPS/SLATS Deck (11):
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 WTB’s to activate (ROAM)?
• Runaway (symmetrical)
• Overspeed (flap mechanism)
• Movement (un-commanded)
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?
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 flaps/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
