FLAPS / SLATS

Question 1

With only Green hydraulic system pressure available, will both the flaps and slats operate?

Answer 1

Yes, at ½ speed

Question 2

What system prevents flap or slat asymmetry?

Answer 2

Wing Tip Brakes (WTB)

Question 3

What causes the WTBs to activate (ROAM)?

Answer 3

a. Runaway (Move handle to 1, all go to 3)
b. Overspeed (Flap jack screw breaks)
c. Asymmetry (Both on one side move farther)
d. Movement (Never touch handle, ALL just move)

Question 4

If the WTB activates due to a flap asymmetry can the slats still operate?

Answer 4

Yes, only flap operation is inhibited

Question 5

How may Slat/Flap Control Computers (SFCC) are installed?

Answer 5

2

Question 6

What would occur if one SFCC failed?

Answer 6

The slats and flaps would continue to operate, but at half speed

Question 7

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

Answer 7

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

Question 8

When will the Automatic Retraction System (ARS) operate?

Answer 8

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

Question 9

What is Alpha Lock?

Answer 9

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

Question 10

When the FLAP legend appears in cyan on the upper ECAM display what is indicated?

Answer 10

Flaps/slats in transit

Question 11

What happens to the ailerons when the flaps are extended?

Answer 11

The ailerons droop 5°
