Editing Landing (section)

=== Environmental factors ===
Factors such as [[crosswind]] where the pilot will use a [[crab landing]] or a [[slip landing]] will cause pilots to land slightly faster and sometimes with different aircraft attitude to ensure a safe landing.

Other factors affecting a particular landing might include: the plane size, [[wind]], [[weight]], runway length, obstacles, [[ground effect in aircraft|ground effects]], [[weather]], runway altitude, [[air temperature]], [[atmospheric pressure|air pressure]], [[air traffic control]], [[visibility]], [[avionics]] and the overall situation.

For example, landing a multi-engine [[turboprop]] military such as a [[C-130 Hercules]], under fire in a grass field in a war zone, requires different skills and precautions than landing a single engine plane such as a [[Cessna 150]] on a paved runway in uncontrolled airspace, which is different from landing an airliner such as an [[Airbus A380]] at a major airport with [[air traffic control]].

[[Required Navigation Performance]] (RNP) is being used more and more. Rather than using radio beacons, the airplane uses GPS-navigation for landing using this technique. This translates into a much more fluid ascent, which results in decreased noise, and decreased fuel consumption.<ref>{{cite web |url=http://www.geaviation.com/systems/products-and-services/performance-based-navigation/learning-rnp.html |title=Required Navigation Performance &#124; GE Aviation Systems |publisher=GE Aviation |access-date=2012-07-16 |url-status=dead |archive-url=https://web.archive.org/web/20120729132651/http://www.geaviation.com/systems/products-and-services/performance-based-navigation/learning-rnp.html |archive-date=2012-07-29 }}</ref>
