DETAILED OPERATION
Screen will be displayed with the following changes.
1. Key 5 will now read VNAV OFF and there is a new VNAV message box.
12. If the DESCEND IN counter is greater than 00:00, the new message box will show
DESCEND IN with the counter value.
13. When the DESCEND IN counter reaches 00:00, the alarm will sound and a
message will be displayed across the Screen saying START DESCENT NOW. Key
5 will change to ALARM OFF then back to VNAV OFF. Once Key 5 is hit or the
alarm times out, the START DESCENT message will disappear and the VNAV
message box will now show ADVISORY ALT: XXXXX ft and count down. The
descent angle will be fixed at this point to prevent changes in ground speed from
altering the descent profile.
When the advisory altitude is within 500 feet of the TO altitude, the alarm will sound again
and a message will be displayed across the Screen saying FINAL ALT IMMINENT. Key 5
will change to ALARM OFF then back to VNAV OFF. Once Key 5 is hit or the alarm times
out, the advisory altitude will continue to count down until it reaches the TO altitude.
VNAV mode will then cancel automatically.
If you wish to perform a DIRECT TO or select a new flight plan the VNAV Mode will need
to be cancelled.
VNAV can be used for climbing as well as descending. If the FROM altitude is set to a
lower value than the TO altitude then everywhere the words DESCENT and DESCEND
appear, the word CLIMB will be used instead.
