Crew Resource Management and Aviation Communications
What the exam tests
CRM and communications questions test closed-loop communication, standard phraseology, assertiveness, leadership, briefings, and coordination among dispatcher, crew, ATC, and ground staff. The exam focuses on preventing misunderstanding under workload.
Core concepts
- Closed-loop communication: sender transmits, receiver reads back or paraphrases, sender confirms.
- Standard ICAO phraseology reduces ambiguity. Avoid slang, guessed values, and partial readbacks.
- Assertiveness means raising a concern clearly and persistently until resolved. Hierarchy should not silence a valid safety query.
- Effective briefings set expectations for threats, weather, runway, fuel, and alternates.
- Language proficiency and plain-language clarification are required when standard phraseology is insufficient.
Worked example
ATC clears: "Climb FL290, squawk 4271." The crew reads back: "Climb FL290, squawk 4271." The controller confirms. Later, a revised clearance gives "descend FL190" but the readback says "FL290." The controller corrects it. The dispatcher, hearing a mismatch in a relayed report, asks the crew to verify the clearance rather than assuming the first value is correct.
Traps
Assuming a readback is correct because it was fast; accepting an ambiguous clearance; failing to challenge a senior person; and mixing company language with ATC phraseology. A good challenge is specific: state the concern, the evidence, and the desired action.
