SELECTIVE CALLING (SELCAL) INTRODUCTION Selective Calling (SELCAL) is an International Civil Aviation Organization (ICAO) managed communications method used to notify aircraft that a ound radio station wishes to communicate. The current rules for SELCAL code assignment, with sixteen available letters, limit the number of possible allowable codes w

Nov 24, 2021 · ICAO Selcal (also known as AVCALL, ANNEX 10, or just SELCAL) is a HF / VHF aviation selective calling system used by ground stations to initiate radio communications with aircraft.

1.1 The Selective Calling (SELCAL) is a signalling method transmitted over HF or VHF which relieves the flight crew from maintaining a listening watch on assigned frequencies.

There is a concern that the continued duplication of SELCAL codes may lead to operational errors potentially impacting aviation safety. ASRI is seeking support and ICAO guidance for SELCAL code pool expansion to further reduce the probability of an operational error.

Apr 2, 2018 · RINC managements agreed to work together without a formalized agreement. ARINC was responsible for accepting all applications from outside organizations interested in obtaining SELCAL assignments and for issuing SELCAL codes. ARINC would periodically coordinate with ICAO on the number of actual code assignme

SELCAL is a signaling method which can alert an individual aircraft that a ground station wishes to communicate with it. SELCAL signals can be transmitted over either HF or VHF RTF.

Selcal, or Selective Calling as it is more correctly known, is an automatic recognition system that is operated by a two-tone signal. Two letters are grouped together as a pair so that only two tones are required for one call, for example "AB "+"CD".

With the ICAO Communications Panel approving the global implementation of SELCAL 32 for the 30 Nov 2022, ANSPs and aircraft operators should now be considering the necessary steps to be compatible with the ICAO SARPs amendment. The below …

In international aviation, SELCAL or SelCal is a selective-calling radio system that can alert an aircraft's crew that a ground radio station wishes to communicate with the aircraft.

Here are two program solutions to encode/generate/simulate aeronautical selcals: The SELCAL consists of 2x 2 tones, according to the following specification: 4.8.1 Recommendation. - Where a SELCAL system is installed, the following system characteristics should be applied. a) Transmitted code.
