FCTM BUSS Flashcards
When the BUSS is active:
‐ The AP/FD and A/THR must be disconnected,
‐ The F/CTL Laws are in Alternate law,
‐ The STALL warning remains operative,
‐ Cabin pressure must be controlled manually,
‐ Depending on the ADIRS standard, the FPV can be available on one or both PFDs as soon as the flight crew switch off all ADRs,.
‐ CAUTION When flying with the BUSS, do not use the speed brakes.
CAUTION When flying with the BUSS, do not use the speed brakes.
Flying with speed brakes extended affects the relationship between the speed and AOA, and therefore the BUSS may provide erroneous data.
The flight crew adjusts the pitch and thrust to fly the:
green area of the speed scale.
The BUSS is directly based on the current:
Angle-Of-Attack (AOA). Any longitudinal input on the stick will induce an AOA change, and therefore will cause the BUSS to move. If not, the flight crew must disregard the BUSS and use pitch and thrust tables.
When the flight crew turns off all ADRs, the
NAV ADR 1+2+3 FAULT ECAM alert triggers. The flight crew apply the associated procedure then, as requested by the ECAM, apply the “ALL ADR OFF” QRH procedure.
This QRH procedure provides guidance to:
‐ Manually control the cabin pressure,
‐ Prepare the approach and landing.
For approach, the flight crew should perform a
stabilized approach. The flight crew should change the aircraft configuration with level wings.
To retract or to extend flaps, apply the following technique:
‐ Before retracting the next flaps configuration, fly the upper part of the green band,
‐ Before extending the next flaps configuration, fly the lower part of the green band.
This technique limits the excursion in the amber zones when changing the flaps configuration.
