2.4.2 Altitude Alerting
The Altitude Alerting function provides the pilot with visual and aural
alerts (if interfaced to an audio panel) when approaching the Selected Altitude.
Whenever the Selected Altitude is changed, the Altitude Alerter is reset.
NOTE : The Altitude Alerter function may be disabled in some installations.
When the Altitude Alerter is disabled, pressing the ALT key will result in
an “ALT KEY INOP” message.
The following occur when approaching the Selected Altitude:
• Upon passing through 1000 feet of the Selected Altitude, the Selected
Altitude (shown above the Altimeter) changes to black text on a light blue
background, and flashes for five seconds. An audio alert may be generated,
if configured.
• When the aircraft passes within 200 feet of the Selected Altitude, the Selected
Altitude changes to light blue text on a black background and flashes for
five seconds and an aural tone may be generated, if configured.
• After reaching the Selected Altitude, if the pilot flies outside the deviation
band (beyond ±200 feet of the Selected Altitude), the Selected Altitude
changes to yellow text on a black background, flashes for five seconds, and
an aural tone is generated.

NOTE : The aural tone when approaching the selected altitude may be
configured at installation for either 200 feet or 1000 feet. The tone when
deviating from the selected altitude always occurs at 200 feet.
2.4.3 Changing Barometric Setting
The Barometric Setting affects the altitude values shown on the PFD.
Barometric pressure units may be displayed as either inches (in) or hectopascals
(hpa). See
System Display Units
in Section 3 for more detail.

BARO
key to activate Baro mode.
