When conducting a touch and go landing, when should throttles be advanced for takeoff?

Advancing the throttles for takeoff during a touch and go landing should occur not until the flaps are at ½. This procedure is essential for ensuring proper aircraft control and performance during the transition from landing to takeoff.

When flaps are set to the appropriate position for takeoff, it optimizes lift and control, allowing for a safer and more effective acceleration. Advancing throttles prematurely, such as immediately upon touchdown, could lead to an unstable situation since the aircraft is still in contact with the runway and not configured for a clean takeoff. Similarly, waiting until the engines have spooled down may not provide the necessary thrust promptly, which could extend the landing phase unnecessarily. Advancing the throttles based on the airspeed being below 80 knots doesn’t take into account the aircraft configuration and control aspects relevant to this phase of flight.

Configuring the flaps properly before advancing the throttles is a critical part of ensuring the aircraft reaches the desired performance metrics for a safe and efficient takeoff following a touch and go landing.
