RADIO 1/4 or 2/4 page (General considerations)
For all radio types, the following applies:
Two frequencies/channels are displayed for each radio. When a new frequency/channel is entered, it is placed
to the right of the active frequency, in the stand-by position. The associated line select key toggles the stand-
by/active frequency/channel and vice-versa (when the scratchpad is empty).
The FMS allows the user to select a frequency by entering one of the following elements in the scratchpad and
pressing the associated line select key:
• a preset number
• the identifier (for VOR radio: from the navigation database as 1st priority and from the radio library as 2nd
priority; for all other radios from the radio library as 1st priority)
• the frequency/channel value
If a valid preset number is entered, the corresponding frequency/channel (from the library) is displayed. Preset
or ident entries have priority over the frequency/channel when entered simultaneously according to the slash
rule (e.g. 01//122.5). In this case the frequency entered will be that of the corresponding preset or ident from the
library.
The FMS allows the user to select the previous/next preset from the library by entering '+' or '-' in the scratchpad
and pressing the associated softkey.
The FMS provides frequency/channel validation by verifying the user requested frequency/channel matches the
radio feedback frequency/channel.
For navigation radios (excluding ATC) the following applies:
The 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 operating frequencies for the Navigation radios are defined in each respective radio section. The FMS does
not accept values out of range. An error message will appear in the scratchpad, if invalid entries are made by
the user.
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 FMS does not require trailing/leading zeros for frequency entry.
