Estimated Time En-Route Data Field
The estimated time en-route data window displays the
calculated time en route as the distance to the destination waypoint,
divided by the ground speed. If the ETE is greater then 10 minutes
then the format is HH:MM. If HH is less than 10 then no leading
zeroes are displayed. Otherwise the format is MM:SS, with leading
zeroes displayed. If the ETE is invalid or greater than 24 hours then
"--:--" will be displayed.
Examples are shown in the following table:
Flight Time Data Field
The flight time data window displays the current flight
duration in HH:MM format. The flight timer displays the current time
in flight or, if the flight has ended, the duration of the flight just ended.
The flight timer begins counting when the ground speed exceeds 20
knots. The flight timer continues until the unit shuts down, or until
the ground speed has been below 3 knots for 5 minutes. If the
ground speed exceeds 20 knots after the flight time had previously
stopped then the flight time continues from the previous flight time.
Groundspeed Data Field
The ground speed data window displays the current
aircraft ground speed in the configured units.
