Flight Instruments Flashcards
In Normal Law what occurs as the aircraft slows to Alpha Protection?
- AOA Protection becomes active, and:
- A- autopilot disconnects
- S- speed brakes retract
- A- side stick behavior changes from load-factor demand to AOA proportional to side stick deflection
- P- pitch trim (nose up) inhibited
- What flight control law is represented by the indications shown on the airspeed tape?
- If the speed brakes are extended, what will occur if airspeed decreases below the speed shown by the arrow (inside the yellow and black arc)?
- Normal Law
- Speed brakes auto retract at Alpha Prot
What protection occurs at a predetermined angle if attack between Alpha Prot and Alpha Max?
Alpha Floor protection engages. Autothrust provides TOGA thrust regardless of thrust lever position provided Autothrust is available/ operable. Although Alpha Floor can engage at any airspeed, it will certainly engage between A Prot and A Max
What does Alpha Max represent?
The speed corresponding to the maximum angle of attack that the aircraft can obtain in Normal Law
If the side stick is held full aft, will Alpha Max be exceeded?
No, Alpha Max cannot be exceeded even if the side stick is pulled and held fully back
If the side stick is held full aft, will the aircraft enter a stall?
No, Alpha Max cannot be exceeded even if the side stick is pulled and held back. (Barring extraordinary circumstances, such as extreme environmental conditions).
If the side stick is held full aft, will the aircraft enter a stall?
No, Alpha Max cannot be exceeded even if the side stick is pulled and held fully back. (Barring extraordinary circumstances, such as extreme environmental conditions).
During the approach, in Normal Law, you hear the aural warning, “SPEED, SPEED, SPEED”. What does this represent?
Low Energy Warning. Thrust must be increased. Decreasing pitch alone is not enough to recover a positive flight path angle
During your base turn on approach, (in Normal Law) you hear the aural warning, “SPEED, SPEED, SPEED”. What does this represent?
Low Energy Warning. Thrust must be increased. Decreasing pitch alone is not enough to recover a positive flight path angle
What flight control law is represented by the indications shown on the airspeed tape? (Only red and black low speed tape and no yellow and black tape)
Alternate (or Direct) Law
In alternate law, what will occur as the airspeed approaches Vsw?
With low speed stability, a gentle nose-down command is initiated which attempts to keep the speed from slowing further
The aircraft is in Alternate Law.
What would occur if the Side Stick is pulled further aft?
The airplane can be stalled in alternate law
Given this indication, what will occur if the Side Stick is pulled or held aft?
With low speed stability, a gentle nose-down command is initiated which attempts to keep the speed from slowing further. This command can be overridden by the sidestick
- What is indicated by the equal “=” sign at the top of the speed tape?
- What occurs if the aircraft reaches this speed?
- The speed at which Normal Law overspeed protection becomes active. Vmo +6 knots.
- A pitch up demand is introduced, and the autopilot disconnects. When the protection is active, pilot side stick authority is reduced, and cannot overpower the automatic pitch up
What is indicated by the green “equal” sign at the top of the speed tape?
The speed at which Normal Law overspeed protection becomes active
