In a fifteen-second interval takeoff, when does the wingman release the brakes?

The correct timing for the wingman to release the brakes is after the 15-second interval, rather than during the initial actions taken by the flight lead or at any earlier point during the takeoff sequence.

In a fifteen-second interval takeoff procedure, coordination between the lead and wingman is critical. The wingman must maintain proper timing relative to the lead aircraft’s actions. The timing ensures that both aircraft takeoff in a coordinated manner, thereby optimizing safety and performance during the transition from ground to flight.

The phrase "immediately after lead releases the brakes" suggests that the wingman would react to the lead's actions, which does not accommodate the structured timing of the fifteen-second procedure. Similarly, the lead’s advancement of power or calling readiness does not dictate the precise moment for the wingman’s brake release. This coordination practice is designed to enforce discipline and maintain separation throughout the takeoff.

Therefore, understanding that the wingman specifically needs to wait until the designated fifteen seconds elapse before releasing their brakes demonstrates the importance of adhering to established timing protocols in multi-aircraft operations.
