Photogrammetry Measurements of Passenger Entry Doors

Abstract

All airplanes must be pressurized when altitudes exceed 12,500 ft. (3,800 m). The typical cruising altitude of commercial airliners is generally between 29,000 ft. and 40,000 ft. (from 8,800 m to 12,200 m). At this altitude, interior cabins are pressurized both for safety as well as passenger comfort. INITIAL TESTING ON NEW AIRCRAFT MODELS Pressure testing is performed on every line number (aircraft) as part of the U.S. Federal Aviation Administration (FAA) 22 THE JOURNAL OF THE CMSC/AUTUMN 2015
