In case of fire, what should be turned off?

Landing lights
Oxygen supply
Navigation systems
Hydraulic pumps

The correct answer is: Oxygen supply

In the event of a fire, turning off the oxygen supply is critical due to the role oxygen plays in fueling a fire. Oxygen supports combustion, so minimizing its availability can help to reduce the fire's intensity or spread. When a fire is present, ventilating areas with oxygen or allowing an oxygen-rich environment can exacerbate the situation, making it more challenging to control the fire or eliminate it. While it's important to manage the other systems mentioned, the direct impact of oxygen on fire dynamics makes shutting off the oxygen supply an immediate priority. The other systems like landing lights, navigation systems, and hydraulic pumps may not pose the same immediate risk to fire spread and can often remain operational to aid in safe evacuation or emergency procedures until deemed otherwise.
