NORMAL LAW Flashcards
In the NORMAL LAW GRND MODE, to what is the movement of the flight controls in proportion?
Side stick deflection
What is inhibited at > 33 degrees of Bank?
Automatic Pitch Trim
What is demanded by pitch and roll input via the side stick during flight?
Load-factor (G)
What happens to the Flight Path Angle if the stick is released to neutral during flight?
Holds the Flight Path Angle based on Load Factor demand
What are the G-load protection limits?
Clean Config: +2.5 to -1.0 G
Any other Config: +2.0 to 0.0 G
Descending through 30’ RA on the approach, what happens to the Pitch Control?
Reduces pitch to -2 degrees Nose Down Attitude over a period of 8 seconds
What are the Pitch Attitude Limits in Normal Law?
Normal SPD/CONFIG 0-3: 30 degrees NUA
Low SPD/CONFIG 0-3: 25 degrees NUA
Normal SPD/CONFIG FULL: 25 degrees NUA
Low SPD/CONFIG FULL: 20 degrees NUA
NDA limit - 15 degrees in every CONFIG
What are the Protections in Normal Law?
4 x vertical, 1 x lateral
- High Speed
- Low Speed
- High AoA (Alpha)
- Load Factor
- Bank
What is the lowest speed achievable with hands off the stick, no inputs?
V Alpha Prot
What is the lowest speed achievable with side stick full back?
V alpha Max
When system is in Alpha Prot, what does side stick movement command?
Alpha (AoA) (so not pitch!)
What happens if at Alpha Max, the side stick is released to neutral?
AoA returns to Alpha Prot & Stays there until pilot takes action
What happens to the thrust if A.FLOOR (Alpha Floor) is annunciated?
TOGA N1 is set regardless of the thrust lever position
When does HI SPD protection activate?
VMO/MMO value + 6 knots (green indication on speed tape in barber-pole)
What happens to the PITCH if HI SPD is activated?
A permanent (slow) pitch order is applied by the flight computer
Pitch trim is frozen
Bank angle set to 0 degrees
Speed brought back to just below VMO/MMO
What happens if side stick is pushed forward in HI SPD PROTECTION?
Nose goes down but with reduced side stick authority (max VMO/MMO value + 36 knot)
What is the Max Bank Angle?
67 degrees
What happens to the FD/FMA if more than 45 degrees of bank is applied?
- FD-bars disappear
- AP disconnects
What is the max bank angle for a “no hands” turn?
33 degrees
What is the max bank angle in:
HI SPD Protection?
Alpha Protection?
HI SPD: manually 40 degrees (no hands 0 roll back)
Alpha Prot: manually 45 degrees
