How many seals does the canopy of the aircraft have?

The canopy of the T-6A aircraft has two types of seals: a non-inflatable weather seal and an inflatable pressure seal. The non-inflatable weather seal functions to prevent moisture and air from entering the cockpit, ensuring a comfortable and safe environment for the pilots during flight. The inflatable pressure seal, on the other hand, is designed to create an effective barrier under varying atmospheric pressures, particularly important during certain phases of flight, such as when the aircraft is at high altitudes.

Having both seals enhances the aircraft's ability to maintain a secure and pressurized cockpit, which is crucial for the safety of the crew. This design feature is integral to the aircraft's operational capabilities and has been specifically engineered to meet the demands of flight training and performance.
