40. FLAPS/SLATS Flashcards
What system prevents Flap or Slat asymmetry?
Wing Tip Brakes (WTB)
How many 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?
o CONF 1+F is used for takeoff and provides both slats (position 1) + flaps.
o CONF 1 is used in‐flight and is slats only.
When will the Automatic Retraction System 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.
What happens to the ailerons when the flaps are extended?
The ailerons droop 5°
