What power setting is used by number 2 during an interval takeoff?

During an interval takeoff, number 2's power setting should be at maximum throttle, which allows for optimal performance and ensures a sufficient takeoff speed while maintaining proper separation from number 1. The use of maximum power is crucial because it helps number 2 achieve the necessary climb gradient and airspeed, particularly in formation flight where maintaining spacing and coordination with the lead aircraft is essential.

Using maximum power during this phase of the takeoff ensures that number 2 can quickly follow number 1 with the ability to react to any changes in the lead aircraft's altitude or speed. This is particularly important in formation flying, where precise timing and spacing are crucial for safety and efficiency. Other power settings such as 90%, 75%, or 85% throttle might not provide the adequate performance needed in the initial stages of takeoff, where both performance and safety are paramount.
