What is a necessary precaution when transitioning between fuel tanks on an aircraft?

When transitioning between fuel tanks on an aircraft, it is vital to ensure that the fuel supply in one tank does not become exhausted. This precaution is crucial because running a tank dry can lead to engine power loss or even engine failure, especially in aircraft with multiple fuel tanks and engines that rely on a steady fuel supply.

Maintaining an adequate fuel supply in each tank ensures that the engine receives a continuous flow of fuel during operation. This is particularly important in multi-engine planes, where the loss of power from one engine can severely affect the aircraft's control and safety.

Switching tanks at regular intervals or maintaining constant fuel pressure can be part of good practice, but the primary focus should be on ensuring that you do not run out of fuel in any one tank during operation. Using a fuel booster pump may be necessary under certain conditions, but it is not universally required for safe fuel tank transitions. By prioritizing the prevention of fuel exhaustion, pilots can significantly enhance safety during flight transitions between tanks.
