Flaps / Slats Flashcards
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? **Not a MQF Question
• CONF1+F • This configuration has a maximum speed 215 knots, with automatic retraction of flaps occurring at 210 knots.
What is the normal flap setting for a go-around?
Retract one step
How are the flaps and slats affected if only GREEN hydraulic system pressure available?
The flaps and slats will still operate, but at half speed
What system prevents flap or slat asymmetry?
Wing Tip Brakes (WTB)
What causes the WTBs to activate?
• Runaway • Over speed (flaps) • Asymmetry • Movement (un-commanded)
If the WTBs activate due to a flap asymmetry, how are the slats affected?
The slats can still operate normally - only flap operation is inhibited.
How many Slat/Flap Control Computers (SFCC) are installed? **Not a MQF Question
Two
What would occur if one SFCC failed? **Not a MQF Question
The slats and flaps would continue to operate, but at half speed.
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
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.
- NOTE: The ARS ONLY retracts the Flaps. NOT the Slats.
What is ALPHA LOCK?
This function inhibits retracting SLATS from 1 to 0 at a high angle of attack and low airspeed.
When the FLAP legend appears in blue on the E/WD, what is indicated? **Not a MQF Question
Flaps/slats in transit
What happens to the ailerons when the flaps are extended?
The ailerons droop
