+/- 75º
When using the rudder pedals for steering, when does the steering angle begin to reduce?
Starts reduction at 40 knots and progressively reduces to zero degrees at 130 knots
What protection/s do you have in Normal Law?
Load Factor Limitation (Clean = +2.5 / -1.0; Dirty = +2.0 / 0)
Pitch Attitude (30˚ UP/15˚ DN)
Bank Angle (67˚)
High Speed
High Angle of Attack (AOA alpha protection)
How does the High Speed Protection operate?
If Vmo/Mmo plus a predetermined factor is exceeded, the system induces a pitch-up input to limit aircraft speed
Can the pilot override the auto pitch-up associated with High Speed Protection in Normal Law?
No
What is Alpha Max?
The maximum angle of attack allowed in Normal Law, indicated by the top of the red strip on the airspeed scale
Q: How does High Angle of Attack Protection operate?
When the angle of attack exceeds Alpha Protection, pitch trim ceases and angle of attack is now proportional to sidestick deflection, not to exceed Alpha Max even with full aft sidestick deflection
What protection do you have in Alternate Law?
Load Factor
High speed stability (Nose up command) but can be overridden
Low speed stability (Nose down command) but can be overridden
Can you override the high stability in Alternate Law?
Yes
What protections do you have in Direct Law?
None
If you are in Pitch Alternate Law, what law would Roll be?
Direct Law
When is there a direct relationship between sidestick and flight control surface deflection?
When in Normal Law, Ground Mode
When in Direct Law
When below 50 feet in Flare Mode (pitch only)
How would you get into Abnormal Attitude Law?
By exceeding approximately double the Normal Law limits
What is the purpose of Abnormal Attitude Law?
Allows the aircraft to be recovered from an unusual attitude
Does the aircraft remain in abnormal attitude law once it returns within the normal flight envelope.
No. When the aircraft returns within the normal flight envelope, the abnormal attitude law disengages.
Will Abnormal Law revert to Direct Law on landing gear extension?
No
What PFD indications indicate Normal Law?
Green = for pitch, bank, and overspeed limits
Amber/black (alpha protection) airspeed tape
What is indicated if the PFD pitch and bank limits are amber X’s?
You are not in Normal Law
What would cause you to revert to another law?
Multiple failures of redundant systems
What law are you in when you perform the flight control check on the ground?
Normal Law, Ground Mode
Can the aircraft be flown with a loss of all flight control computers?
Yes, in Mechanical Backup
How is the airplane controlled in Mechanical Backup?
Pitch – Trim wheel (horizontal stabilizer)
Yaw – Rudder pedals (rudder)
Speed – Thrust levers
What is ROPS/ROW/ROP?
ROPS: Runway Overrun Prevention System
ROPS is made up of two sub-functions, ROW and ROP. The ROW function generates alerts which incite the flight crew to perform a Go-Around whereas the ROP function generates alerts which incite the flight crew to apply available deceleration means.
ROW: Runway Overrun Warning
ROW FUNCTION: The ROW function provides enhanced flight crew awareness about the approach stabilization and the capacity to land on available landing distance.
ROP: Runway Overrun Protection
ROP FUNCTION: The ROP function provides enhanced flight crew awareness about the deceleration and capacity to stop before the end of the runway.
In aircraft equipped with ROPS, when might you get a ROW amber “RWY TOO SHORT” vs. a Red “RWY TOO SHORT” message on the PFD?
Below 400 ft, if the computation for landing distance is more than the LDA:
• The amber “RWY TOO SHORT” message is displayed on both PFDs. This message flashes for 9s and then remains steady. This message is not associated to an aural alert.
Below 200 ft, if the computation for landing distance is more than the LDA:
• The red “RWY TOO SHORT” message is displayed on both PFDs. This message flashes for 9s and then remains steady. In addition, the following repetitive aural alert triggers: “RUNWAY TOO SHORT”.
When does the ROP trigger visual and aural alerts?
On ground, the ROP function computes the braking distance for the current aircraft and runway conditions. If current braking performance is not sufficient to stop on LDA, it triggers visual and aural alerts.
What happens if an overrun situation is detected?
As soon as an overrun situation is detected “MAX BRAKING” and “MAX REVERSE” messages are displayed on both PFDs. They flash for 9 s and then remain steady.
