What is the minimum amount of LOX liters required for a daily on a legacy aircraft?

The minimum amount of liquid oxygen (LOX) required for a daily on a legacy aircraft is 8 liters. This requirement stems from the operational needs of the aircraft, which utilize LOX for in-flight respiration systems. This amount ensures that the crew has an adequate supply of oxygen for a day of training or flight operations.

The specifications for LOX are based on factors such as the duration and type of flights, as well as the number of crew members that need to be supported. Ensuring that there are 8 liters of LOX available minimizes the risk of oxygen depletion during missions and maintains a safe environment for pilots and crew.

This standardization across legacy aircraft is crucial for operational readiness and safety, which is why it is an established requirement. Other quantities might not meet the full operational needs, leading to potential issues with oxygen supply during flight operations.
