What should be done once a positive rate of climb is confirmed during a touch and go?

Once a positive rate of climb is confirmed during a touch and go, the appropriate action is to raise the flaps and retract the gear. This procedure is essential in the climb phase of flight, as it ensures the aircraft is configured for optimal performance while ascending.

Raising the flaps reduces drag and allows the aircraft to gain altitude more effectively. The gear retraction at this stage also minimizes drag, enhancing climb performance. These actions are crucial for maintaining a safe ascent and preparing the aircraft for the subsequent phases of flight.

In a touch-and-go scenario, confirming a positive climb rate is critical before making any changes to the configuration of the aircraft, which is why retraction of the gear and flaps is prioritized after this confirmation. The other options don't align with the best practices for this stage of flight; for instance, immediately turning to downwind or reducing thrust to idle would potentially compromise safety and performance during the climb.
