Normal Law protections Flashcards
Which Protections are available in Alternate law without reduced protection?
Only th eload factor limitation
Load factor limits:
-1G to +2.5G clean
0 to +2G (other configurations)
Pitch attitude protection limits pitch attitude to:
-30º NU in Conf 0 to 3
-25º NU in conf FULL
-15º ND
Pitch attitude protection: FD bars disappear from PFD when pitch exceeds…
25ºNU or 13ºND
Which protection has priority over all others?
High AOA protection
When the High AOA protection is activated, the normal law demand is modified and the sidestick input is … demand, instead of a load factor demand
… an AOA demand
While on High AOA protection, what happens if the flight crew holds full sidestick?
the aircraft stabilizes at an AOA close to but less than the 1g stall.
While flying aMAX, what happens when the crew releases the sidestick?
AOA returns to aPROT and stays there
High speed protection: In a dive situation, if there is no sidestick input, the aircraft will…
slightly overshoot VMO/MMO and fly back towards the envelope
High speed protection: In a dive situation, if the sidestick is maintained full forward…
-Aircraft significantly overshoots VMO/MMO
then,
-Nose-down authority reduces to 0
The Alpha floor protection:
comands TOGA thrust
Which protections are available under Alternate law?
-Load Factor
-Low speed stability
-High speed stability
Which protections are available under Direct Law?
No protections
What protections do you have in Normal law?
-Load factor
-Pitch
-High AOA
-High speed
-Bank angle
Bank angle protection?
-Max is 67º
-positive spiral stability brings bank back to 33º
-Above 45º, AP disconnects and FD bars disappear
