What is the standard phraseology used when an aircraft must hold due to wake turbulence?

• A. STAND BY FOR TAKEOFF
• B. HOLD AT HOLDING POINT DUE WAKE TURBULENCE
• C. HOLD SHORT OF RUNWAY DUE WAKE TURBULENCE
• D. HOLD SHORT RUNWAY DUE TO WAKE TURBULENCE

Answer: (C)

When an aircraft must hold due to wake turbulence, the standard phraseology is to instruct the aircraft to "hold short of runway due wake turbulence." This terminology clearly communicates the specific action required—namely, that the aircraft should remain positioned short of the active runway rather than proceeding onto it.

This phraseology is essential for maintaining safety in the vicinity of an active runway where another aircraft's wake may pose a hazard. Using the term "hold short" indicates that the aircraft must stop before entering the runway, thus preventing any potential encounters with the turbulence generated by preceding aircraft.

Other choices may lack the clarity or specificity required in aviation communication, which is vital for effective air traffic control and safety. Proper phraseology is critical in aviation to avoid misunderstandings that could compromise safety.
