What is the MLG tire pressure when the aircraft is afloat?

The correct tire pressure for the Main Landing Gear (MLG) when the F/A-18 E/F aircraft is afloat is indeed 350 +/- 5 PSI. Maintaining the correct tire pressure is crucial for the safety and performance of the aircraft, especially during critical phases such as landing and takeoff.

When the aircraft is afloat, it is important to ensure that the tire pressure is set at this specified level to accommodate various factors including the weight of the aircraft, the buoyancy in water, and the dynamics of landing on a carrier deck. The specified pressure helps in providing the right amount of support and stability to the aircraft while it's being serviced or prepared for launch.

Higher or lower tire pressures than specified can lead to potential risks such as uneven load distribution or a higher likelihood of tire blowouts, both of which could compromise the safety and operability of the aircraft. Proper tire maintenance, including regular checks of tire pressure, is essential for the overall performance and safety of the F/A-18 E/F.
