Mode data to all DME ground stations within the DME range
(LOS).
FREQ Frequency
Frequency (1) Function in 860E-5 (-005/-006) to allow tuning 2-
Agile by-5 inputs from on-board FMCS/PNCS systems.
Channeling may be as often as every 5 seconds. The
6-wire output data is modified for input to an FMCS
or PNCS.
(2) The ability of a receiver-transmitter to rapidly and
continually shift operating frequency.
