Quick answer

ROC-A candidates should use ISED RIC-21 for official exam scope and NAV CANADA phraseology material to understand practical Canadian communication examples.

Transport Canada has highlighted NAV CANADA’s phraseology guides and explains that standard phraseology improves efficiency and safety by reducing misunderstanding and frequency congestion.

What ROC-A candidates should learn first

Start with these areas:

1. Phonetic alphabet
2. Numbers and decimals
3. Standard words and phrases
4. Aircraft identification
5. General radio communication structure
6. Hearback/readback concept
7. Calls to different ATS units
8. Uncontrolled aerodrome-style awareness calls

How this connects to ROC-A

RIC-21 covers the official ROC-A study scope, including speech transmission techniques, time and date, phonetic alphabet, transmission of numbers, procedural words, call signs, calling procedures, distress communications, and urgency communications.

The best study approach is to learn RIC-21 first, then use NAV CANADA examples to understand how radio communication looks in real aviation scenarios.

Practical example structure

A useful radio call structure often answers:

• Who are you calling?
• Who are you?
• Where are you?
• What do you want or intend to do?
• What information must be confirmed?

This structure helps candidates avoid rambling and makes communication predictable.

Common candidate mistakes

• Speaking too quickly.
• Using too many filler words.
• Memorizing without understanding.
• Ignoring readbacks.
• Not practising out loud.
• Treating phraseology like casual conversation.

How to practise

Use this routine:

1. Pick one phraseology topic.
2. Read the example.
3. Rewrite the call in plain English.
4. Say the radio call out loud.
5. Remove unnecessary words.
6. Repeat until the call sounds clear and organized.
