The altitude alert activates as follows:
If more than 0.12g required to capture FCP window altitude - steady amber PFD altitude box
Deviation of 150 feet or more from FCP window altitude - flashing amber PFD altitude box and
1,000 feet from the FCP window altitude - PFD altitude box turns steady amber.
and tone. Active only on first approach to the FCP window altitude and is inhibited when
aircraft is within 150 feet. If more than 0.12g is required to capture the FCP window altitude
and that altitude is more than 1000 feet from the current baro-altitude, the PFD altitude box
will be flashing amber. This condition is typically the reason why one may hear two successive
altitude tones while approaching an altitude.
The altitude alert system is inhibited if the AFS is in glideslope capture mode or
flap setting is more than 31.5 degrees (landing).
The tone consists of a C-chord.
