ALERT/WARNING AREA
FIGURE 6.2.1-2A: MODE 1 OUTER CURVE (TURBOFAN)
The Mode 1 outer alert boundary is biased to the right as a function of glideslope deviation above (fly down) the beam in
order to prevent unwanted alerts while re-positioning from above the beam.
This bias is applied to the outer envelope, which effectively moves the envelope to the right with increasing deviation above
the glideslope beam. This term is weighted to provide "0 FPM" of bias when the aircraft is centered on the beam and "300
FPM" of bias when the aircraft is two dots above the beam. The term is also modified close to the ground by the value of
radio altitude, varying from zero bias at zero feet altitude up to 100% bias above 100 feet radio altitude. These functions vary
linearly between these two limiting values. The bias is not applied to the inner envelope.
A bias is applied to both the outer and inner envelopes in the event that the pilot selects flap override. For turboprop aircraft
(MKVI or MKVIII EGPWS), flap override biasing can be enabled by the pilot anywhere above 50 feet terrain clearance, and
will be automatically disabled at or below 50 feet during landing. For turbofan aircraft (MKVIII EGPWS only), the same
applies, except that the flap override bias will be disabled at 10 feet. If the flap override biasing is in effect, then the envelope
modulation biasing and the glideslope deviation biasing shall be disabled. The bias will be 300 FPM to the right.
