SYSTEM DESCRIPTION
5.1
System Description
The KN 63 DME measures slant-range distance (aircraft to ground station). It is a remote
mounted, 200 channel DME, employing a solid-state transmitter and large scale integrated circuit
(LSI) technology. All tuning is done electronically using a single crystal, digital, frequency
synthesizer. Slant range is measured digitally using two LSI's. Another LSI is employed in the
digital frequency synthesizer.
The KN 63 DME outputs a minimum of 50 watts peak pulsed power and a nominal 100 watts
through CI 105-6 DME antenna.
The KN 63 DME is interfaced with the G1000H for tuning and display. The PFD will display the
DME information in the DME Information Window, which shows the DME tuning mode, frequency,
and distance. The KN 63 DME audio is used to identify the DME ground stations being received.
The KN 63 is powered by the avionics bus and is protected by a 3 amp circuit breaker
DME
(CB36) located on the left side of the circuit breaker panel (Figure 16). Power to the KN 63 may
also be controlled by a remote
DME
ON/OFF switch located at the bottom of the circuit breaker
panel (Figure 16).
Refer to Figure 34
for the KN 63 unit location. Refer to 28-AC-075 Rotorcraft Flight Manual
Supplement for KN 63 operation.
