200 ft agl
500 ft agl
Maximum airspeed for hands–on operation in cruise following a failure:
120 kts
Maximum airspeed for hands–on operation in ILS approach following a failure:
100 kts
ILS approach limitations

In flight:
Max. OAT for AFCS continuous operation in case of loss of avionics ventilation
30º C
Below ____ IAS and with IAS mode engaged, use of the GA mode is prohibited
60kts
STICK CENTERING LIMITATION
Maximum wind
15 Kts
Second APM disengagement or failure
BOTH AUTOPILOTS LOST
1. Flying controls – Hands-on
If under SP/DPIFR operation:
2. LAND AS SOON AS PRACTICABLE
Light remains illuminated for 10s
Total loss of one cyclic axis series actuation
LOSS OF CYCLIC TRIM + ACTUATION IN EITHER PITCH OR ROLL AXIS
1. Flying controls – Hands-on
If under SPIFR operation:
- LAND AS SOON AS PRACTICABLE
Second AHRS failure
(When losing 1st AHRS = RCU to working system)
1. Flying controls – Hands-on
If under SP/DPIFR operation
2. LAND AS SOON AS POSSIBLE
AHRS failure
1. Flying controls – Hands-on
2. Artificial horizon on PFD and stby AI – Compare
3. RCU – Reconfigure to valid AHRS
If under SP/DPIFR operation
- LAND AS SOON AS PRACTICABLE
Localized AHRS discrepancy
1. Flying controls – Hands-on
2. Artificial horizon on PFD and stby AI – Compare
3. RCU – Reconfigure to valid AHRS
If under SP/DPIFR operation
4. LAND AS SOON AS PRACTICABLE
WARNING: Carefully determine valid AHRS. Keep hand on cyclic stick during AHRS configuration. Monitor a/c respond while carefulli releasing cyclic stick after reconfiguration.
System will be in DSAS (Level 3) until reconfiguration.
Cyclic and yaw (double) trim failure
1. Flying controls – Hands-on
If under SP/DPIFR operation
- LAND AS SOON AS PRACTICABLE
Cyclic trim failure
1. Flying controls – Fly attentive
– Recenter P R if necessary
– Confirm upper modes in turbulence
If under SPIFR operation
- LAND AS SOON AS PRACTICABLE
Roll mode (HDG, LOC, VOR, VOR.A) decoupling: HDG discrepancy
In IFR or if reengagement of previously engaged or new roll mode (HDG, LOC, VOR, VOR.A) is intended:
- Flying controls – Hands–on
- ND compass rose – Compare with standby compass
3. RCU – Reconfigure to the AHRS that gene– rates the same heading as standby compass
- APMS – Arm/engage roll mode
If aircraft is out of a previously effective LOC/ VOR/ VOR.A capture condition:
- Flying controls – Bring aircraft back to capture condition
- Mode performance – Monitor
If flight shall be continued with an other mode (different from HDG, LOC, VOR, VOR.A):
- APMS – Select other mode or keep autotrim
Roll mode (HDG, LOC, VOR, VOR.A) degradation: HDG discrepancy
In IFR or if roll mode shall be kept:
- Flying controls – Hands–on
- ND compass rose – Compare with standby compass
3. RCU – Reconfigure to the AHRS that generates the same heading as standby compass
- Mode performance – Monitor
If flight shall be continued with another mode (different from HDG, LOC, VOR, VOR.A):
- APMS – Select desired mode
Roll mode (HDG, LOC, VOR, VOR.A) degradation: HDG sensor failure
In IFR or if roll mode shall be kept:
- Flying controls – Hands–on
2. RCU – Reconfigure to the AHRS of alternate side
- Mode performance – Monitor
If flight shall be continued with another mode (different from HDG, LOC, VOR, VOR.A):
- APMS – Select desired mode
