Flaps/Slats-even/odd

Question 1

How are the flaps and slats affected if only GREEN hydraulic system
pressure available?

Answer 1

The flaps and slats will still operate, but at half speed

Question 2

What system prevents flap or slat asymmetry?

Answer 2

Wing Tip Brakes (WTB)

Question 3

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

Answer 3

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

Question 4

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

Answer 4

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

Question 5

When will the Automatic Retraction System (ARS) operate?

Answer 5

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

Question 6

What is ALPHA LOCK?

Answer 6

This function inhibits retracting slats from 1 to 0 at a high angle of attack and
low airspeed.

Question 7

What happens to the ailerons when the flaps are extended?

Answer 7

The ailerons droopshould
