    EGPWS. The information in this document is intended as a general expla- nation of the Honeywell MK VI & MK VIII EGPWS. It contains a general description of system performance assuming identified options are active, and highlights deviations in system perfor- mance resulting when a feature is disabled.
  • Page 5 Note: This feature is not available in the initial release (-001) for the MK VI and MK VIII. • A Terrain Clearance Floor (TCF) function adds an addi- tional element of protection by alerting the pilot of possible premature descent.
  • Page 6 For specific effectivity, refer to an applicable Airplane Flight Manual (AFM) or EGPWS Airplane Flight Manual Supple- ment (AFMS). The MK VI/MK VIII EGPWS is packaged in a non-ARINC rack Physical mounted enclosure weighing less than 4 lbs. No special vibration Description isolation or forced air-cooling is required.
