In large [[transport category]] (airliner) aircraft, pilots land the aircraft by "flying the airplane on to the runway."{{citation needed|date=February 2023}} The airspeed and attitude (pitch angle)<!-- The correct term is "attitude" here, not altitude, please do not change this without discussion on the talk page first --> of the plane are adjusted for landing. Thrust and pitch must be adjusted together,<ref name="Roy">{{cite journal |last1=Jeffrey A. |first1=Roy |title=The Stabilized Approach |journal=FAA Aviation News |date=May–June 1990 |page=4 |url=https://books.google.com/books?id=bIgsnbWISb8C&pg=RA8-PA4 |access-date=28 February 2023 |publisher=Flight Standards' Accident Prevention Program Branch, Federal Aviation Administration, Department of Transportation |language=en}}</ref> however the technique is reversed compared to light aircraft.<ref name="NASA Technical Paper">{{cite book |title=NASA Technical Paper |date=1981 |publisher=National Aeronautics and Space Administration, Scientific and Technical Information Office |page=6 |url=https://books.google.com/books?id=vAMDAAAAIAAJ |access-date=28 February 2023 |language=en}}</ref> In large aircraft, thrust is used to control airspeed and pitch is used to control rate of descent.<ref name="NTSB">{{cite book |title=Aircraft Accident Report, United Airlines Flight 232, 19 July 1989 |publisher=National Transportation Safety Board |location=Appendix D |page=123 |url=https://books.google.com/books?id=2QU6AQAAMAAJ |language=en}}</ref> The airspeed is kept well above stall speed and at a constant rate of descent. A [[Landing flare|flare]] is performed just before landing, and the descent rate is significantly reduced, causing a light touch down. Upon touchdown, [[lift dumper|spoiler]]s (sometimes called "lift dumpers") are deployed to dramatically reduce the lift and transfer the aircraft's weight to its wheels, where mechanical [[braking]], such as an [[autobrake]] system, can take effect. [[Reverse thrust]] is used by many [[jet aircraft]] to help slow down just after touch-down, redirecting engine exhaust forward instead of back. Some [[Propeller (aircraft)|propeller]]-driven airplanes also have this feature, where the blades of the propeller are re-angled to push air forward instead of back using the 'beta range'.
