How is the cabin pressurized in the Beechcraft Travel Air BE‑95?

The Beechcraft Travel Air BE-95 is designed without a pressurized cabin. Instead, it operates as a light aircraft that does not utilize a cabin pressurization system. This design means that the aircraft relies on atmospheric pressure during flight, making it suitable for operations at lower altitudes where pressurization is not a necessity. The lack of a pressurized cabin limits operational altitude but also simplifies the design and maintenance of the aircraft.

The other options suggest features like a fully pressurized cabin or pressurization through an air conditioning system, neither of which applies to this aircraft. Additionally, using supplemental oxygen is not a primary method of cabin pressurization; rather, it can be used as a safety measure for higher altitudes in unpressurized aircraft, while still not addressing the absence of a pressurization system in this specific model.
