Bendix/King KN 63 DME Receiver
The KN 63 is a complete 100 watt, 200 channel remote DME system. Distances
up to 389 NM, groundspeeds up to 999 kts. and time-to-station up to 99
minutes are computed digitally and displayed simultaneously.
Distance lock-on is virtually instantaneous with accurate groundspeed and
time-to-station readouts following in less than one minute.
Moving the source selector switch away from the OFF position turns on the
unit. DME channelling is dependent on selection of N1 or N2 (NAV 1 or NAV
2).
NOTE
For the purpose of this simulation, the DME HOLD function has been replaced
with a GPS option for lateral navigation of a GPS flight plan.
Once the unit has locked on to the selected station, DME distance will be
displayed in 0.1 NM increments up to 99.9 NM; then in increments of 1 NM to
389 NM.
Distance is calculated by electronically converting the elapsed time for
signals to travel to and from the ground station. Groundspeed calculations
are based on the rate of change of DME distance.
Time-to-station is calculated by dividing the DME distance by the computed
groundspeed. Therefore, accurate groundspeed and time-to-station
readouts are only available when the aircraft is tracking directly to or from a
beacon.
When the function switch is set to N1 the DME channel is controlled by the
frequency on NAV 1. Similarly, selection of N2 will enable NAV 2 to control the
DME frequency.
If the unit is set to GPS, the flight plan loaded into the DGPS will display the
DME data.
The DME facility may be identified by selecting DME on the audio control
system.
