Radio Telephony General Operating Procedures and Phraseology
Core concepts
Radio telephony (RT) is a disciplined, standardised language. For Brunei DCA CPL(A) VFR, you must know the standard words and phrases, the phonetic alphabet, and the correct call structure. Key concepts: use of the phonetic alphabet for letters, standard pronunciation of numbers (e.g., 'three' not 'tree', 'fife' for five, 'niner' for nine), and transmission techniques (speak clearly, not too fast, use standard phraseology). You must know the order of a call: station called, your callsign, message. Readback requirements are covered in domain 5, but here focus on general phraseology: 'roger', 'wilco', 'affirm', 'negative', 'say again', 'standby', 'disregard', 'correction', 'request', 'cleared', 'approved', 'maintain', 'report'. Understand the use of 'over' and 'out' (though 'out' is rarely used on VHF). Know the distress and urgency prefixes (MAYDAY, PAN PAN) but they are detailed in domain 6. Traps: confusing 'roger' (I received your transmission) with 'wilco' (I will comply); using 'repeat' instead of 'say again'; mispronouncing numbers; forgetting to use the phonetic alphabet for registration letters; using non-standard phrases like 'OK' or 'copy'. Also, know that 'standby' means wait, not an approval. Worked example: To request taxi, you call: 'Brunei Ground, Cessna Five Six Alpha Bravo, request taxi from stand three to runway two zero, VFR to the training area.' Note the structure: station, callsign, request with position and intention. Rule of thumb: always use the standard phrase; if unsure, ask 'say again' or 'confirm'.
