Aircraft pressurization test apparatus and method of using same

摘要

A method of using an aircraft pressurization test apparatus to perform diagnostic tests on an aircraft while the aircraft is at a first region of a ground site, such as an aircraft hanger. The method comprises: positioning the aircraft at the first region of the ground site, using a first delivery line in a manner to enable fluid communication between a shop air aperture of the aircraft pressurization test apparatus and an air coupler of a shop air system at the ground site; using a second delivery line in a manner to enable fluid communication between an aircraft cabin pressurization inlet opening of the aircraft and a delivery air aperture of the aircraft pressurization test apparatus; delivering air from a compressor of the shop air system through the aircraft cabin pressurization inlet opening and into the aircraft cabin via the shop air aperture and the delivery air aperture of the aircraft pressurization test apparatus; and regulating the delivery of air from the compressor of the shop air system through the aircraft cabin pressurization inlet opening by changing characteristics of the flow path between the shop air aperture and the delivery air aperture.
