Mark VII enhanced ground proximity warning system (EGPWS) accepts a variety of aircraft parameters as inputs, applying proprietary alerting algorithms and providing the flight crew with aural alert messages, visual annunciations and a display of terrain. Mark VII interfaces with our optional bi-axial accelerometer if inertial reference system (IRS) or attitude heading reference systems (AHRS) inputs are not available.

Key system details are:

• Reactive wind shear alerting provides visual and aural warnings of impending wind shear via algorithms that can detect increases or decreases in aircraft performance
• Geometric altitude algorithm overcomes barometric altimetry limitations, like cold weather operations
• Peaks display depicting the highest and lowest elevation terrain within the display range at any altitude
• Runway field clearance floor (RFCF) protects against inadvertent landings below airport runway thresholds at airports that are much higher than surrounding terrain
• Reduced nuisance alarms to increase pilot confidence
• Radar autotilt® allows the EGPWS to provide terrain elevation data to compatible radars for controlling the tilt of the radar antenna during its scan
• SmartRunway® and SmartLanding® protect against runway incursions and excursions
• Auto pop-up change from radar to terrain display in the event of a terrain alert, reducing pilot workload during
• Altitude callouts of height above terrain or field elevation during final approach
• Optional 8-channel or dual 12-channel internal global positioning system (GPS) card
