How can you verify the amount of LOX in the aircraft?

To determine the correct method for verifying the amount of Liquid Oxygen (LOX) in the aircraft, checking the LOX gauge located on the left-hand side rear of the seat is the most reliable approach. This gauge provides a real-time reading of the LOX levels, allowing personnel to assess whether there's a sufficient supply for operational needs. This information is crucial for mission safety and effectiveness, particularly in environments where oxygen supply may be limited.

While inspecting the LOX tank visually from the front may give some indication of the tank's condition, it does not provide an accurate measurement of the liquid oxygen levels. Similarly, consulting the aircraft manual may offer guidance on how to monitor LOX levels in general but does not provide a direct current status. Asking the maintenance crew for the latest reading can be helpful, but it relies on others rather than using the available instrumentation designed specifically for this purpose. Using the gauge is the most immediate and precise method to ensure safe and effective operations.
