Airbus Study Guide Flashcards
What happens during ground mode as the aircraft gets airborne?
Ground mode is progressively blended out and flight mode becomes effective.
What kind of control of the flight controls in ground mode?
Direct control of elevator, ailerons and spoilers.
What does the SIDESTICK command in flight mode in the pitch axis?
A change in G.
What does the SIDESTICK command in the roll axis in flight mode?
A roll rate.
What happens at 50ft during the landing in flare mode?
The aircraft memorizes the attitude at 50 feet and then at 30 feet the system reduces the pitch attitude to -2 degrees over 8 seconds.
What are the protections in normal law?
- Load limit limitation
- Pitch attitude protection
- Bank angle protection
- High speed protection
- High angle of attack protection
- Alpha floor protection
What does the load limitation do?
It limits the load factor automatically.
What are the pitch attitude protection limitations?
+30 NU in conf0-3
(Reduced to +25 low speed)
+25 NU in conf full
(Reduced to +20 low speed)
-15 Nose down
How are the limits of the pitch attitude protection displayed on the PFD?
By green = symbols
What happens to the FD bars when the pitch attitude limit is approaching?
Will disappear and will return after flight path correction.
What happens is a pilot releases the SIDESTICK at bank angles above 33 degrees?
The bank angle automatically reduced to 33 degrees
What is the bank angle limit when angle of attack protection is active?
45 degrees
What is the maximum bank angle when the pilot holds full lateral SIDESTICK deflection?
67 degrees
How is the bank angle limit displayed in the PFD?
By a green = symbol
If high speed protection is active and the pilot maintains full lateral deflection, what is the maximum bank angle?
40 degrees.
What happens to the bank angle when high speed protection is operative and the SIDESTICK is released?
Returns to 0 degrees
What happens when the bank angle exceeds 45 degrees?
- autopilot disconnects
- Flight director bars disappear
When do the flight director bars return after they disappeared during bank angle protection.
When bank angle is reduced below 40 degrees.
What happens as speed increases above Vmo/ Mmo?
SIDESTICK nose down authority is reduced and a permanent nose up order is applied.
As high speed protection becomes active, when will the autopilot disconnect?
Vmo + 6 kts
Mmo + 0.01
How is the speed where the high speed protection starts displayed on the speed tape?
A green = symbol at Vmo+6
What does the sidestick demand between Valpha PROT and Valpha Max?
Angle of attack.
What happens if the pilot pulls the sidestick all the way back to Alpha Max and then releases it?
The speed returns to alpha PROT.
Which protection in normal law has priority over all other protections?
High angle of attack protection.
