What phraseology is used when issuing wake turbulence advisories for aircraft landing behind Category B or D aircraft?

The correct phraseology for issuing wake turbulence advisories when an aircraft is landing behind Category B (Small) or Category D (Heavy) aircraft is "CAUTION WAKE TURBULENCE, HEAVY AIRBUS THREE FORTY, TWO MILE FINAL." This phrase clearly identifies the situation and provides the necessary details for the following aircraft.

In this context, the term "CAUTION WAKE TURBULENCE" serves as an important alert, warning pilots of the potential hazards associated with wake turbulence from larger aircraft. The phrase specifies the aircraft type and its proximity to the landing aircraft, which is crucial for ensuring safe operations. Including "HEAVY" indicates that the Airbus A340 is a large aircraft, which is significant because it generates more wake turbulence than smaller aircraft.

The mention of "TWO MILE FINAL" provides additional situational awareness, informing the pilot of the distance to the runway threshold and allowing them to adjust their approach and be prepared for any potential turbulence effects.

Other options do not accurately describe a wake turbulence advisory for landing aircraft following Category B or D aircraft. They either refer to aircraft that are departing or do not properly incorporate the necessary information about the proximity or type of aircraft, making them less appropriate for the
