Worked example questions
Independently authored revision questions in the same multiple-choice format as the exam. Try each one before opening the answer.
Worked example: what the standard reply means
Not quite. The correct answer is B.
Correct answer: B
- A. This is the meaning of WILCO, not ROGER. Roger does not promise any action.
- B. Correct. Roger confirms receipt only. It answers no question and commits to no action.
- C. This is the meaning of AFFIRM. Roger is not a yes or no answer, even when it is used in reply to a question.
- D. This confuses roger with a request such as SAY AGAIN. Roger signals that the message was understood, the opposite of needing it repeated.
Step by step
- Recall the one meaning of roger: the last transmission was received and understood.
- Rule out the neighbouring words: affirm means yes, negative means no, and wilco means understood and will comply.
- None of those meanings attach to roger, so a bare 'roger' after an instruction confirms receipt only, nothing more.
Worked example: reading a level and heading aloud
Not quite. The correct answer is B.
Correct answer: B
- A. This reads the level and heading as whole numbers. Both are transmitted digit by digit, not as rounded quantities.
- B. Correct. Each digit is pronounced separately, and the digit nine always carries its standard pronunciation, niner.
- C. The digit grouping is right, but the digit nine is read as plain 'nine' instead of the standard 'niner', the pronunciation that avoids confusion with similar-sounding digits.
- D. This pads a two-digit flight level and a three-digit heading with an extra leading zero that does not belong to either figure.
Step by step
- Levels and headings are transmitted by pronouncing each digit separately, never as a whole number.
- The digit nine is always spoken as niner, in every context, to prevent it being misheard.
- FL90 is two digits, niner and zero, so it is read as flight level niner zero.
- A heading of 300 degrees is three digits, read as three zero zero, the same convention whether climbing, descending, or turning.
What this subject asks of you
Phraseology is predictable once you revise it as standard patterns instead of isolated sentences.
What the paper tests
Phraseology and procedural recallWhy it matters
The exam tests your understanding of clear, standard radio exchanges and the situations in which different calls or terms are required.Best next step
Use timed practice and spaced recall together so weak areas come back before they decay.

How to study it
- Practise phraseology out loud so the patterns become natural.
- Group calls by stage of flight so the context stays clear.
- Review emergency and urgency language separately because those mistakes are often avoidable.
Where VFR Communications candidates lose marks
Common traps
- Knowing the general meaning but missing the exact phrase order.
- Mixing VFR phraseology with IFR expectations.
- Ignoring standard readback requirements.
The hardest VFR Communications exam areas
Where candidates actually lose marks in 091, and why.
Classifying a scenario as distress or urgency
Exam stems describe symptoms rather than use the word MAYDAY or PAN PAN outright, so marks are lost by reacting to how dramatic a scenario sounds instead of checking it against the two precise definitions.The exact meaning of ROGER, WILCO, and AFFIRM
The three words look interchangeable in everyday English, but the exam treats them as three separate commitments (received, will comply, and yes), and the standard distractors are built by swapping one for another.Building a complete call from a described scenario
A complete call needs four fixed elements in a fixed order, and most dropped marks come from a plausible-sounding transmission that is missing exactly one of them, most often the level or the station being addressed.
