When should wake turbulence cautionary advisories be issued to aircraft?

• A. When aircraft are landing
• B. For VFR aircraft being radar vectored behind larger aircraft
• C. For aircraft departing
• D. Whenever turbulence is likely

Answer: (B)

The issuance of wake turbulence cautionary advisories is particularly important for VFR (Visual Flight Rules) aircraft being radar vectored behind larger aircraft. This is because larger aircraft, especially those classified as heavy or large, generate significant wake turbulence that can pose a hazard to smaller following aircraft.

By providing advisories to VFR aircraft in this scenario, air traffic controllers help ensure that pilots are aware of the potential for wake turbulence and can maintain an appropriate distance or alter their flight path as necessary. This proactive measure is crucial for maintaining safety in busy airspace where different sizes of aircraft are operating in close proximity to each other.

Other situations, such as when aircraft are landing or departing, might involve considerations for wake turbulence, but the specific cautionary advisories should be targeted at those aircraft that are immediately at risk, such as the VFR aircraft following larger ones. This targeted approach helps minimize confusion and enhances overall safety.
