Primary Flight Display
If the destination airport is lost (e.g., the pilot clears the flight plan on the navigator):
•
Temperature compensation is unavailable
•
Minimums altitude source type switches from TEMP COMP to BARO
To resume temperature compensation, reselect TEMP COMP after loading a new
destination airport into the navigator.
2.7.4 MDA/DH Alerting
MDA and DH alerts are based on barometric altitude or optional radar altitude.
Alerting is inhibited while the aircraft is on the ground. The radar altimeter option is
only available in aircraft with a compatible radar altimeter interfaced to the
TXi system.
Both radar altitude and barometric minimums settings are lost following a unit
power cycle. Controls for setting MDA and DH alerting behavior reside in the
Minimums menu.
As the aircraft descends, the bug changes color to reflect the current altitude above
minimums. Alerting is armed once the aircraft is >150 ft above min altitude.
•
White at 50 ft above min
•
Cyan at 150 ft above min
CONDITION ALERT INDICATION
Initial MDA/DH
When the MDA/DH is initially set:
•
Cyan altitude value with bracket pointer displays at the
bottom of the altimeter tape
•
BARO or RAD ALT minimums remain boxed until the
MDA/DH altitude is visible on the altimeter tape
•
Minimums display “RA” when using RAD ALT settings
Once MDA/DH altitude is within altitude tape display
range, the boxed value is removed and the cyan minimums
bug begins tracking with the altimeter tape.
Within 100 ft of
MDA/DH
•
Bug turns white
Reaching MDA/DH
•
Bug turns yellow
•
Aural alert: “Minimums, minimums”
Both TEMP COMP and BARO share the minimums altitude
function. Switching between these two source types does not
alter the specified altitude value.
