FAA AMT (Aviation Maintenance Technician) Airframe Practice Exam

In some aircraft with several fuel tanks, the possible danger of allowing the fuel supply in one tank to become exhausted before the selector valve is switched to another tank is prevented by the installation of

1. a fuel pressure warning signal system

2. an automatic tank switching system

3. a manual override system

4. an emergency fuel distributor

The correct answer is: a fuel pressure warning signal system

In some aircraft with several fuel tanks, the possible danger of allowing the fuel supply in one tank to become exhausted before the selector valve is switched to another tank is prevented by the installation of a fuel pressure warning signal system. This system helps alert the pilot or the maintenance crew when the fuel supply in one tank is running low, prompting them to switch to another tank to ensure a continuous supply of fuel to the engine. Option B, an automatic tank switching system, might seem like a viable solution, but such a system could potentially malfunction or lead to unintended consequences. Option C, a manual override system, would rely on human intervention without providing an early warning mechanism like the fuel pressure warning signal system does. Option D, an emergency fuel distributor, is not a commonly used or recognized component for preventing fuel exhaustion in aircraft with multiple fuel tanks.
