Separate a Category I aircraft conducting a touch-and-go on the same runway as a preceding Category H aircraft departure by ___ minutes from the time the Category H aircraft ___.

Explanation:
The key idea is wake turbulence separation when operations share the same runway. A heavier aircraft creates wake vortices that can affect following airplanes, so a time-based separation is used after the lead departure lifts off or rotates to give those vortices time to dissipate. In this scenario, the correct rule is to wait three minutes from the moment the preceding heavy aircraft rotates or takes off before the Category I aircraft can perform its touch-and-go on the same runway. This timing reflects the need for sufficient wake dissipation for safe subsequent operations, and the reference point is the moment the heavy aircraft rotates or lifts off, which marks when its wake begins affecting the runway environment. Shorter intervals would not reliably allow wake vortices to dissipate, increasing risk during the touch-and-go. A longer interval isn’t required here for safety, given the specified configuration and categories. By using three minutes and the rotation/takeoff moment as the reference, the spacing aligns with established wake turbulence separation practices for this case.
