Communications (VFR)
VFR communications questions test standard phraseology, readback discipline and correct use of frequencies. Learn the structure of a radio call: station addressed, your call sign, position and altitude, intentions, and any request. Know the phonetic alphabet, standard words (ROGER, WILCO, AFFIRM, NEGATIVE, STANDBY, SAY AGAIN, CORRECTION), and the meaning of a clearance limit. Understand distress (MAYDAY) versus urgency (PAN PAN) and when each is appropriate, and know the emergency frequency 121.5 MHz.
Traps: reading back items that are not required while omitting those that are; using "ROGER" as if it meant "yes"; confusing Q-codes; and failing to include your position and altitude in a position report. Remember that a clearance must be read back in full when it contains a route, altitude, heading or frequency change. If you miss part of a transmission, say "SAY AGAIN" rather than guessing.
Worked example: ATC says "ABC, cleared to enter controlled airspace, maintain 2,500 ft, squawk 4271." Your readback must include the clearance, the altitude and the squawk: "Cleared to enter controlled airspace, maintaining 2,500 ft, squawk 4271, ABC." Rule of thumb: if the transmission contains a number that affects your flight path or identification, read it back. Keep transmissions brief, use standard phraseology, and never transmit on a frequency without first listening to establish it is clear.
