Foreword System Sec 1 PFD Sec 2 MFD Sec 3 Features Avoidance Hazard Sec 4 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. The Altitude Alerter is independent of any autopilot installed in the aircraft. 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, flashes for five seconds. • 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 is generated. • 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. Within 1000 ft Within 200 ft Deviation of ±200 ft Figure 2-18 Altitude Alerting Visual Annunciations 2.4.3 Changing Barometric Setting The Barometric Setting affects the altitude values shown on the unit.
