Final answer:
In a short obstacle landing, power should generally go to idle at the start of the flare to allow for a controlled reduction of speed for a short landing.
Step-by-step explanation:
In a short obstacle landing, power should generally go to idle at the start of the flare to allow for a controlled reduction of speed for a short landing.For a short obstacle landing, the correct moment to bring the power to idle is typically at the B) Start of the flare. This action allows the aircraft to bleed off excess speed and energy to achieve a slow touchdown speed, which is essential for stopping within a short distance after landing. It's crucial to manage the aircraft's energy properly to ensure a safe landing. Going to idle power too early or too late can affect the landing performance adversely and may lead to an overshoot or a hard touchdown.
