e/Airstair

Information
has gloss	eng: An airstair is a passenger staircase that is built in to an airliner — often, though not always, on the inside of a clamshell-style door. The stairs can be raised or lowered while the aircraft is on the ground, allowing passengers and ground personnel to board or depart the aircraft without the need for a mobile staircase or a jetway. Some piston-era airliners were equipped with airstairs, including the Martin 2-0-2, Martin 4-0-4, and versions of the Douglas DC-3 specially modified in the 1940s by Southwest Airways. Airstairs have become less common because of increasing airport infrastructure, but they are still popular on small regional airliners and aircraft which operate into less-well equipped airports.
lexicalization	eng: airstair
instance of	(noun) a flight of stairs or a flight of steps stairs, steps
