Prior Company, LCC all-Airbus operator (USA). Training department was basically "Airbus factory curriculum"
"Cleared for approach" (APPR is green/active in MCDU by now)
Push APPR pushbutton, arm the approach
Set "bottom altitude" FAF/FAP altitude in altitude window FCU
PUSH altitude knob
Set missed approach at FINAL APP
Current Company, mix of Boeing and Airbus
"Cleared for the approach"
Push APPR pushbutton, arm the approach
Do nothing else
Set missed approach altitude at FINAL APP
Both "work" but....
Thanks
Neither is correct.
if your aircraft has xLS, the arming conditions for the approach are the same as an iLS, and the missed approach altitude is set like an ILS with F-G/S * & F-LOC*. Procedural descents according to the chart are performed the same as a procedural ILS.
Without xLS, flying the bricks. Approach is armed when the TO waypoint in the FM shows the start of the coded descent, eg shows the start of the 3 degree descent after the waypoint. Should see a descent arrow at this waypoint. Pressing approach prior to this waypoint can result in altitude constraints not being followed.
Missed approach altitude set at FINAL APP.
Prior to pressing APPR, the lowest altitude on the procedure can be placed in the FCU, and DES used, this will ensure constraints are complied with.
