For navigation radios (excluding ATC) the following applies:
The CMA-9000 FMS provides alert mechanisms to inform the pilot of radio failures. Warnings appear if radios
fail or they are not responding to the tuning request.
NOTE: Refer to the specific radio horizontal page description for details.
The CMA-9000 FMS displays all tuned active frequencies in large white font. During the tuning process the
active frequencies are displayed in large inverse white font. If the tuning operation is not successful they are
displayed in small amber font as a warning to the pilot.
The CMA-9000 FMS can be configured to allow burst tuning; either by CMA-9000 Display Panel entry or by a
dedicated radio control head.
The operating frequencies for the Navigation radios are defined in each respective radio section. The CMA-9000
FMS does not accept values out of range. An error message will appear in the scratchpad, if invalid entries are
made by the user.
In some installation, the tuning can be achieved either from the FMS or from a backup controller. If the radio
tuning is disabled from the FMS, entries made to the NAV or ADF radio(s) will generate an entry advisory
message (!RADIO TUNING DISABLED) to inform the pilot that he may no longer tune these radios from the
CMA-9000 FMS.
For communication radios the following applies:
A frequency or channel can be selected by entering the desired value in the scratchpad and pressing the
associated line select key. These radios do not provide tuning validation.
The CMA-9000 FMS does not require trailing/leading zeros for frequency entry.
In some installations, radio tuning can be achieved either from the FMS or from a backup controller. If the radio
tuning is disabled from the FMS, entries made to the COM radio(s) will generate an entry advisory message
(!RADIO TUNING DISABLED) to inform the pilot that he may no longer tune these radios from the CMA-9000
FMS.
For the V/UHF radio, the following applies:
The user interface for the VUHF radio is the same as that of the regular communication radios as described
above but with the following additional features/differences:
In some installations, radio tuning can be achieved either from the FMS or from a backup controller. If the radio
tuning is disabled from the FMS, entries made to the V/UHF radio(s) will inhibit V/UHF page access as well as
generating a data entry error message (!FMS NOT IN CONTROL) in order to inform the pilot that he may no
longer tune these radios from the CMA-9000 FMS.
For frequency in the VHF band, CMA-9000 FMS sets the modulation mode depending on the frequency band.
For frequency in the UHF band, the modulation mode is selectable by the user. The modulation mode and the
frequency ranges to be used are given in the following table.
