DESCRIPTION
Differential analog input connected to the GS
receiver valid output. A 'YES' implies the glideslope
valid signal is greater than a 140mV threshold and
therefore the receiver is valid.
implies the signal is less than this threshold and the
receiver is invalid.NAV Valid
Differential analog input connected to the NAV
receiver valid output. A 'YES' implies the navigation
valid signal is greater than a 140mV threshold and
therefore the receiver is valid.
implies the signal is less than this threshold and the
receiver is invalid.
Open/Ground discrete input connected to the
directional gyro valid output. A 'YES' implies the
input is grounded and therefore the gyro is valid.
Otherwise, 'NO' implies input is open and gyro is
invalid.
Open/Ground discrete input used during production
bench test only. It enables the use of internal control
signals for evaluation purposes, normally disabled
after completion of preflight test. A 'YES' implies the
input is grounded and the function is enabled. A 'NO'
implies the input is open and the function is disabled.
This function should be always be disabled in the
aircraft.
Internal hard--wired strap used on certain versions of
software to identify internal functional differences in
hardware. A 'YES' implies --5201 FCC and a 'NO'
implies all other flavors.
Otherwise, 'NO'
Otherwise, 'NO'
