Communications (VFR Radiotelephony and Phraseology)
Scope
Communications tests VFR radiotelephony, standard phraseology, callsigns, readback, distress and urgency, and Philippine ATC frequencies. Clear, brief transmissions reduce misunderstanding.
Core rules
- Use the aircraft callsign consistently; include type and position on initial contact.
- Read back runway, hold-short, altitude, heading, and frequency instructions.
- Standard words: affirm, negative, roger, wilco, standby, say again, correction.
- Distress: MAYDAY three times; urgency: PAN-PAN three times. Use the phonetic alphabet for letters.
- At a controlled field, request joining instructions and report positions as required.
Worked example
Initial call: 'Manila Tower, Cessna 172 RP-C1234, 10 miles south, inbound for landing, request joining instructions.' Tower: 'RP-C1234, join left downwind runway 24, report downwind.' Readback: 'Join left downwind runway 24, report downwind, RP-C1234.' Reasoning: the call gives who, where, what, and request; the readback confirms the clearance and runway. Do not read back only roger when a clearance requires confirmation.
Traps
Using roger as a readback for a runway clearance. Omitting the callsign or using a shortened form before ATC does. Transmitting long stories on a busy frequency. Confusing MAYDAY with PAN-PAN. Failing to read back a hold-short instruction.
