What is the weather requirement for an interval takeoff?

The appropriate weather requirement for an interval takeoff is set at 1,500 feet of ceiling and 3 miles of visibility. This ensures that pilots have sufficient visual reference and situational awareness to safely manage the interval between departing aircraft. The spacing allows for the safe operation of multiple aircraft while maintaining a safe distance.

In this scenario, the altitude and visibility standards are particularly designed to minimize the risk of collisions and ensure that pilots can see the aircraft in front of them and make necessary adjustments in their performance. By adhering to these requirements, pilots can effectively manage their separation during takeoff, thereby supporting safe flight operations in formation.
