WHY do pilots say HEAVY? Wake Turbulence EXPLAINED BY CAPTAIN JOE
Captain Joe・2 minutes read
Wake turbulence is a critical safety concern for aircraft, influenced by weight, airspeed, and angle of attack, with specific separation distances required based on weight categories. Pilots must be vigilant, with ATC regulations mandating increased separation between aircraft categories to prevent potential turbulence encounters and ensure safe takeoff and landing.
Insights
- Wake turbulence, caused by wingtip vortices from lift generation, is a significant safety concern for aircraft, with strength affected by weight, airspeed, and angle of attack.
- Pilots of heavy aircraft must use the term "heavy" in their call sign to indicate their weight category, ensuring proper separation to prevent wake turbulence encounters, with specific distances mandated by ICAO based on aircraft weight.

Recent questions
What causes wake turbulence in aircraft?
Wake turbulence in aircraft is primarily caused by wingtip vortices generated during lift production. These vortices are influenced by factors such as weight, airspeed, and angle of attack.
How does aircraft weight affect wake turbulence?
Aircraft weight plays a crucial role in wake turbulence, as heavier aircraft produce stronger wingtip vortices. This necessitates specific separation distances to prevent turbulence encounters.
Why do pilots of heavy aircraft use "heavy" in their call sign?
Pilots of heavy aircraft use "heavy" in their call sign to alert others of their weight category. This ensures appropriate separation to avoid encountering wake turbulence.
What is the significance of minimum separation between aircraft?
Minimum separation between aircraft is vital to prevent wake turbulence encounters. Specific distances are required based on weight categories to maintain safety in the airspace.
When is increased separation mandated by ATC regulations?
ATC regulations mandate increased separation when a medium aircraft follows a heavy one. Distances between 5 to 8 nautical miles are required, depending on the weight difference, to prevent turbulence encounters.
