At what point in the flight sequence does number 2 release his brakes during an interval takeoff?

In an interval takeoff, precise timing is crucial for ensuring a safe and efficient departure sequence. The number 2 aircraft in the formation is trained to release their brakes at a specific interval after the number 1 aircraft begins its takeoff roll. Releasing brakes too early or too late can lead to safety concerns or a breakdown in formation.

The correct timing for number 2 to release their brakes is typically set at 6 seconds after number 1 initiates takeoff. This interval allows enough time for the number 1 aircraft to gain sufficient separation and speed before the second aircraft starts its own takeoff sequence. It ensures that both aircraft can achieve their desired flight profiles without interfering with one another, maintaining the integrity of the formation.

In summary, the 6-second delay is a standard practice rooted in safety protocols for interval takeoff, making this option the most appropriate choice.
