Flashcards in FLAPS/SLATS Deck (11):
1

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

Yes, at ½ speed

2

What system prevents Flap or Slat asymmetry?

Wing Tip Brakes (WTB)

3

What causes the WTB’s to activate (ROAM)?

• Runaway (symmetrical)
• Overspeed (flap mechanism)
• Asymmetry
• Movement (un-commanded)

4

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

Yes, only flap operation is inhibited

5

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

2

6

What would occur if one SFCC failed?

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

7

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

8

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

9

What is Alpha Lock?

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

10

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

Flaps/slats in transit

11

What happens to the ailerons when the flaps are extended?

The ailerons droop 5°
