Flight Instruments Flashcards
In Normal Law what occurs as the aircraft slows to Alpha Protection ?
(273)
AOA Protection becomes active, and:
A–autopilotdisconnects
S–speed brakesretract
A–sidestick behavior changes from load-factor demand to AOAproportional to sidestick deflection
P–pitch trim(nose up) inhibited
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)
Normal Law
Speedbrakes retract at Alpha Prot
What protection occurs at a predetermined angle of attack between Alpha Prot and Alpha Max?
(277)
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
What does Alpha Max represent?
(279)
The speed corresponding to the maximum angle of attack that the aircraft can obtain in Normal Law
If the Sidestick 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 Sidestick is held full aft, will the aircraft enter a stall?
(283)
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?
(287)
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?
(289)
Alternate (or Direct) Law
In alternate law, what will occur as the airspeed approaches Vsw?
(291)
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 Sidestick
is pulled further aft?
(293)
The airplane can be stalled in alternate law
Given this indication, what will occur if the Sidestick is pulled or held aft?
(295)
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
297
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 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
What is indicated by the green “equal” sign at the top of the speed tape?
(299)
The speed at which Normal Law overspeedprotection becomes active
With the AP on, A/THR engaged, and the approach phase activated, reference the airspeed indications as shown here…
If you “push speed,” what speed will the A/T maintain?
F Speed
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)
Target ‘bug” can be set to 130, but the aircraft will only slow to Vls
Referencing this speed tape, with A/THR engaged, what speed would the aircraft fly if you selected 130 kts?
Target ‘bug” can be set to 130, but the aircraft will only slow to Vls
