What should be maintained until your aircraft is completely stopped after landing?

The correct answer is that anti-collision lights should be maintained until the aircraft is completely stopped after landing. This is crucial for safety reasons. Keeping the anti-collision lights on alerts ground personnel and other aircraft that your aircraft is still in operation, even as it rolls out after landing. This visibility is essential for maintaining situational awareness on the runway or taxiways, particularly in busy airfield environments where multiple operations may be occurring simultaneously.

In contrast, while landing gear is a critical component to ensure a safe landing, it is not something that needs to be specifically 'maintained' after landing, as it must already be in the down position before touchdown. Flaps may be retracted post-landing to ensure better aerodynamic performance during taxi, and fuel cut-off procedures typically take place once the aircraft is at a complete stop and secured, not while it's still moving on the runway. Thus, maintaining the anti-collision lights until the aircraft has fully stopped serves a significant operational and safety function.
