Flaps / Slats

Question 1

FLAPS / SLATS

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

Answer 1

Ref: (FOM VOL. III-DSC-27-30-10)​ ​

Yes,​ at​ ½ speed

Question 2

FLAPS / SLATS

Q:​ What system prevents​ flap or slat asymmetry?​ ​

Answer 2

Ref: (FOM VOL. III-DSC-27-30-10)​ ​

Wing Tip Brakes (WTB)

Question 3

FLAPS / SLATS

Q:​ What causes the​ WTBs​ to activate?

Answer 3

Ref: (FOM VOL. III-DSC-27-30-10)​ ​

• “ROAM”
• Runaway​ (Move​ handle​ to​ 1,​ all go to 3)​ ​
• Overspeed​ (Flap jack​ screw​ breaks)​ ​
• Asymmetry​ (Both​ on​ one​ side​ move​ farther) ​
• Movement (Never​ touch​ handle,​ ALL just​ move)​

Question 4

FLAPS / SLATS

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

Answer 4

Ref: (FOM VOL. III-DSC-27-30-10)​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

Yes,​ only flap operation is​ inhibited

Question 5

FLAPS / SLATS

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

Answer 5

Ref: (FOM VOL. III-DSC-27-30-10)​ ​

2​

Question 6

FLAPS / SLATS

Q:​ What would occur if​ one SFCC​ failed?​ ​

Answer 6

Ref: (FOM VOL. III-DSC-27-30-10)​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

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

Question 7

FLAPS / SLATS

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

Answer 7

Ref: (FOM VOL. III-DSC-27-30-20)​ ​

• 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 8

FLAPS / SLATS

Q:​ When will​ the​ Automatic Retraction System (ARS)​ operate?​ ​

Answer 8

Ref: (FOM VOL. III-DSC-27-30-10,​ FOM​ VOL.​ III-DSC-27-30-20)

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

Question 9

FLAPS / SLATS

Q:​ What is​ Alpha Lock? ​

Answer 9

Ref: (FOM VOL. III-DSC-27-30-10)​ ​

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

Question 10

FLAPS / SLATS

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

Answer 10

Ref: (FOM VOL. III-DSC-27-30-20)​ ​

Flaps/slats in transit​

Question 11

FLAPS / SLATS

Q:​ What happens to the​ ailerons when​ the flaps are​ extended? ​

Answer 11

Ref: (FOM VOL. III-DSC-20-10-20)​ ​

The​ ailerons​ droop​ 5˚
