Mark VII EGPWS

The Mark VII enhanced ground proximity warning system (EGPWS) is Class A terrain awareness and warning system (TAWS) ideal for fixed-wing aircraft with analog avionics or aircraft with military missions, providing protection against controlled flight into terrain (CFIT) and wind shear.

Overview

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
