The primary goal of the Sierra Pattern is to build and evaluate . In an advanced fly-by-wire aircraft like the Airbus A320, it serves several specific purposes:
After the go-around, the A320 will capture the missed approach altitude in (ALTitude capture) mode. If you don't verify that the FCU altitude has been set to a higher initial level, the aircraft will level off dangerously low. sierra pattern a320
This guide applies to FMS standard 1A/2A (Thales) and 1A/2A (Honeywell) found on A320ceo (2000-2010s) and A320neo (2016+). On very old FMS (pre-1995), Sierra patterns were not computed automatically—pilots had to fly them manually using selected altitude. The primary goal of the Sierra Pattern is
