Department regulations concerning operati on requirements BCL-D- 1.22, Airborne Radio
Equipment (2 pages, in Swedish)
6. Description of content:   It will be required that receivers for aids of navigation
ILS (Instrument landing system) and VOR (VHF Omnidirectional Radio Range) shall beimmune against interference from FM Radio Broadcasting transmitters.  The requirements
related to the equipment has been developed by the International Civil Aviation
Organisation (ICAO), and they are defined in ICAO Annex 10 (Aeronautical
Telecommunications). The requirements shall be complied with during flight in accordance
with the Instrument Flight Rules (IFR) within Swedish Flight Information Region (FIR),
and by Swedish operators and holders of Swedish pilot licences when flying in accordance
with IFR outside Swedish FIR.
7. Objective and rationale, including the na ture of urgent problems where applicable:
The aids for navigation, ILS and VOR, use the VHF-band within the frequency range
108-118 MHz. FM-radio stations broadcasting on close frequencies may under certain
conditions interfere with airborne ILS- and VOR-receivers.  The interference may cause
inadequate or false information to the pilot, without him/her being aware of the disturbance.
In order to eliminate this, the receiver has to be immune against interference from radio
stations broadcasting on the FM-band.  A receiver complying with the provisions inICAO Annex 10 will be able to demonstrate such immunity.  The proposal has been
developed as a result of an agreement between ICAO and the International Tele Union
(ITU).  This means that the relevant European  Authorities in the future will allow radio
stations to use frequencies closer to the frequencies used for aviation purposes, and with
higher effect.G/TBT/N/SWE/2
