FEATURES
Class A certified TAWS
Enhanced Ground Proximity Warning System (EGPWS)
Is a rack mount GPWS and terrain awareness/warning computer
Terrain Awareness System (TAWS) that performs the functions of a standard Ground Proximity Warning System (GPWS) as well as performing the enhanced functions of terrain display & warning
Exceeds FAA TSO-C151b Class A requirements
Optimized for turboprop aircraft and provides protection against controlled flight into terrain (CFIT)
Uses aircraft inputs such as position, attitude, air speed and glideslope, which along with internal terrain, obstacles and airport databases predict a potential conflict between the aircraft's flight path and terrain or obstacle
CFIT warnings include: Rate of descent, terrain closure rate, excessive altitude loss after descent, terrain closure rate, excessive altitude loss after takeoff or missed approach procedures, insufficient terrain clearance, descent below glideslope, and excessive bank angle
Callouts at various radio altitudes & DH minimums during approach
Provides audio caution or warning alerts (visual alerts when coupled w/display)
When coupled with a display, the surrounding terrain can be viewed relative to the aircraft's position, providing strategic terrain information up to 30 mins before a potential terrain conflict
Basic ground proximity warning modes 1-5
Mode 6 altitude callouts and bank angle alert
Terrain clearance floor
Terrain and Obstacle Awareness alert and display
Terrain map w/runways >= 2000' in length
Internal GPS card
Front loading updateable database
External Configuration Module
Internal heated blanket for operation outside of the heated area of the aircaft
Fixed Gear operation
Type of supported displays is limited and does not typically include EFIS display
Terrain database included with the computer is regional having three separtely defined databases for the Americas, Atlantic, and Pacific
MK VI computer uses a Configuration Module, GPS Antenna, OAT Sensor, and Smart Cable (PCMCIA interface)
