The configuration module configuration logic selects a pre-defined set of Mode 6 Callouts. These callouts include altitude
awareness and minimums type callouts. The selected menu will annunciate during the cockpit initiated long self-test
sequence. Selection of menus which are not defined will set Mode 6 INOP to activate system monitor(s). The following table
identifies all of the Mode 6 Callouts that are available.

6.4.1 Minimums Type Callouts
For this callout type, only the basic “Minimums-Minimums” callout is available from the MKVI/MKVIII EGPWS.
The minimums type callouts are given when transitioning the minimums setting with the landing gear down. The minimums
call-out is triggered via a DH input that switches to ground. The DH input may be discrete or, available on the MKVIII
EGPWS only, ARINC 429 for turbofan aircraft. The computer will only respond to the first transition encountered until a
reset term is satisfied.
