When are EMER codes used?

• A. Hijacking
• B. Hijacking, suspected flight crew incapacitated, when phone communication is not possible
• C. Suspected flight crew incapacitated
• D. When phone communication is not possible

Answer: (B)

EMER codes are specialized in-flight signals used to fast-track urgent situations when normal voice communication may be compromised. They’re designed for scenarios that demand immediate ATC awareness and action, such as hijacking or suspected flight crew incapacitation, and also when phone communication is not possible. The option that includes hijacking, suspected flight crew incapacitated, and when phone communication isn’t possible best matches how EMER codes function, because it covers the full range of emergencies these codes are meant to signal. The other choices only describe individual situations and don’t reflect the complete purpose of EMER codes.
