How many minutes should you separate a Category I aircraft conducting a touch-and-go from a preceding Category H aircraft departure?

• A. 1 minute
• B. 2 minutes
• C. 3 minutes
• D. 5 minutes

Answer: (C)

The correct answer pertains to the specific separation requirements established for different aircraft categories in air traffic control operations. In this scenario, a Category I aircraft, which is typically a smaller aircraft, is conducting a touch-and-go operation that involves frequent landings and takeoffs on the same runway.

When separating a Category I aircraft from a preceding Category H aircraft departure, the standard separation time is established as 3 minutes. This time frame ensures that any potential wake turbulence generated by the larger Category H aircraft, known for its significant size and weight, dissipates sufficiently before the Category I aircraft begins its approach or takeoff.

This separation is crucial in maintaining safety in aviation, particularly when considering the impact of wake turbulence, which can affect smaller aircraft significantly more than larger ones. Therefore, the 3-minute separation allows for adequate time for the smaller aircraft to operate safely after the larger one has departed, ensuring a smooth flow of air traffic while minimizing risks associated with wake turbulence effects.
