Flaps / Slats Flashcards

1
Q

When selecting the flap lever to 1 after the flaps have been at CONF 2 or higher, what setting will the flaps and slats go to?

A

• CONF1+F
• This configuration has a maximum speed 215 knots, with automatic
retraction of flaps occurring at 210 knots.

Q

If the WTBs activate due to a flap asymmetry, how are the slats affected?

A

The slats can still operate normally - only flap operation is inhibited.

Q

What flap/slat configurations correspond to position 1 on the FLAPS lever and how do they differ?

A
  • CONF 1+F is used for takeoff and provides both slats (position 1) + flaps
  • CONF 1 is used in-flight and is slats only

Q

When will the Automatic Retraction System (ARS) operate?

A

During acceleration in CONF 1+F, the flaps (not slats) will automatically retract to 0 at 210 knots.

Q

What is ALPHA LOCK?
