What phraseology is used for warning about wake turbulence from a heavy aircraft?

• A. CAUTION WAKE TURBLENCE, LANDING AIRCRAFT
• B. CAUTION WAKE TURBLENCE, HEAVY AIRBUS THREE FORTY
• C. WARNING WAKE TURBLENCE, HEAVY PLAINS
• D. CAUTION WAKE TURBLENCE, LARGE JET ON FINAL

Answer: (B)

The correct phraseology for warning about wake turbulence specifically from a heavy aircraft is crucial for maintaining safety in aviation operations. The phrase used must clearly identify the aircraft type and provide caution to other pilots in the vicinity about potential wake turbulence.

In this case, the phrase "CAUTION WAKE TURBULENCE, HEAVY AIRBUS THREE FORTY" accurately conveys the necessary warning. It designates "heavy" to indicate the classification of the aircraft, which is important as larger aircraft generate more significant wake turbulence. Furthermore, identifying the specific type of aircraft (Airbus 340) allows pilots to recognize the potential risk associated with that particular aircraft and its characteristics.

Using proper and precise phraseology is fundamental in air traffic communication to ensure that all parties are aware of the situation and can take appropriate action when necessary. This helps prevent accidents caused by encounters with wake turbulence, which can be particularly hazardous during takeoff, approach, and landing phases of flight.
