An airplane comprising:
- a vapor cycle air conditioning system that provides air pressurization and supply to a chamber of the airplane;
- a bleed system with at least one port;
- and
- an electric cabin air supply fan,
- wherein the vapor cycle air conditioning system utilizes forced air to provide the air pressurization and supply when the airplane is on ground, the forced air being outside air that is pushed or pulled into the vapor cycle air conditioning system by the electric cabin air supply fan, and
- wherein the vapor cycle air conditioning system utilizes bleed air sourced from the at least one port to provide the air pressurization and supply when the airplane is at cruise, the cabin air supply fan boosting a pressure of the bleed air while the airplane is at cruise.
