9.10.5 Radio operation
Often you will have to call one or more radio stations during the flight. You must
study the equipment in the aircraft thoroughly before use.
9.10.5.1 Radio frequencies
Check that you have the necessary frequencies on the chart where you will use
them. The communication radio operates in the VHF frequency range 118.0 to
136.995 MHz. New radios have a channel spacing of 8.33 KHz, so the number of
channels is 2280 today.
Most aircraft are equipped with a VOR receiver and ADF. These are used to
locate VOR stations and radio beacons (NDB, locator). The frequency of these is
on the ICAO chart and in the VFG. Remember to check the range in the VFG, or
on the backside of the ICAO map.
9.10.5.2 Controlled airspace
Also consider how you should behave if you enter controlled / regulated
airspace. Have some procedures ready so that you can act quickly if necessary.
In particular, you should know:
Who to call - On what frequency
It would also be a good idea to think about where you are when you call, as you
must provide information about this when calling.
9.10.5.3 Radio calls
In controlled airspace, very specific rules apply to radio calls and radio
correspondence in general. These rules are learned on various radio courses, so
only the most general rules will be briefly mentioned here.
