    CAP 413 Radiotelephony Manual Military Aircraft Callsigns 1.9.1 Aircraft Callsigns Military aircraft use callsigns derived from 2 systems. Front line aircraft, in the main, use operational callsigns consisting of a 3 character prefix of numbers and letters (trigraph) suffixed by a 2 number (dinome) mission identifier. Callsigns for Flying Training Units (FTUs) and Search and Rescue (SAR) aircraft use fixed ICAO allocated 3 letter designators with figure suffixes as pilot number callsigns.
