Q

In Normal Law what occurs as the aircraft slows to Alpha Protection ?

(273)

A

AOA Protection becomes active, and:
A–autopilotdisconnects
S–speed brakesretract
A–sidestick behavior changes from load-factor demand to AOA proportional to sidestick deflection
P–pitch trim(nose up) inhibited

Q

What flight control law is represented by the indications shown on the airspeed tape?
If the speedbrakes are extended, what will occur if airspeed decreases below the speed shown by the arrow?

(275)

A

Normal Law

Speedbrakes retract at Alpha Prot

Q

What protection occurs at a predetermined angle of attack between Alpha Prot and Alpha Max?

(277)

A

Alpha Floor protection engages. Autothrustprovides TOGA thrust regardless of thrust lever position provided Autothrustis available/operable. Although Alpha Floor can engage at any airspeed, it will certainly engage between a/Prot& a/Max

Q

If the Sidestick is held full aft, will Alpha Max be exceeded?

A

No, Alpha Max cannot be exceeded even if the side stick is pulled and held fully back

Q

If the Sidestick is held full aft, will the aircraft enter a stall?

(283)

A

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).

Q

During the approach, in Normal Law, you hear the aural warning, “SPEED, SPEED, SPEED”. What does this represent?

A

Low Energy Warning. Thrust must be increased. Decreasing pitch alone is not enough to recover a positive flight path angle

Q

During your base turn on approach, (in Normal Law)
you hear the aural warning, “SPEED, SPEED, SPEED”.
What does this represent?

(287)

A

Low Energy Warning. Thrust must be increased. Decreasing pitch alone is not enough to recover a positive flight path angle

Q

In alternate law, what will occur as the airspeed approaches Vsw?

(291)

A

With low speed stability, a gentle nose-down command is initiated which attempts to keep the speed from slowing further

Q

The aircraft is in Alternate Law.
What would occur
if the Sidestick
is pulled further aft?

(293)

Q

Given this indication, what will occur if the Sidestick is pulled or held aft?

(295)

A

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

Q

297
What is indicated by the equal “ ” sign at the top of the speed tape?

What occurs if the aircraft reaches this speed?

A

The speed at which Normal Law overspeedprotection becomes active. Vmo+6 knots.

A pitch up demand is introduced, and the autopilot disconnects. When the protection is active, pilot sidestick authority is reduced, and cannot overpower the automatic pitch up

Q

With the AP on, A/THR engaged, and the approach phase activated, reference the airspeed indications as shown here…
If you manually select 130kts, what will happen?

(303)

A

Target ‘bug” can be set to 130, but the aircraft will only slow to Vls

17
Q

Referencing this speed tape, with A/THR engaged, what speed would the aircraft fly if you selected 130 kts?

A

Target ‘bug” can be set to 130, but the aircraft will only slow to Vls
