KLMKLM Royal Dutch Airlines, legally Koninklijke Luchtvaart Maatschappij N.V. (ˈkoːnɪŋklɪkə ˈlʏxtvaːrt ˈmaːtsxɑpɛi̯ ˌɛnˈveː, Royal Aviation Company Plc.), is the flag carrier of the Netherlands. KLM is headquartered in Amstelveen, with its hub at nearby Amsterdam Airport Schiphol. It is a subsidiary of the Air France–KLM group and a member of the SkyTeam airline alliance. Founded in 1919, KLM is the oldest operating airline in the world, and has 35,488 employees with a fleet of 110 (excluding subsidiaries) .
Iberia (airline)Iberia (iˈβeɾja), legally incorporated as Iberia Líneas Aéreas de España, S.A. Operadora, Sociedad Unipersonal, is the flag carrier of Spain. Founded in 1927 and based in Madrid, it operates an international network of services from its main base of Madrid–Barajas Airport. Iberia, with Iberia Regional (operated by an independent carrier Air Nostrum) and with Iberia Express, is a part of International Airlines Group. In addition to transporting passengers and freight, Iberia Group carries out related activities, such as aircraft maintenance, handling in airports, IT systems and in-flight catering.
Maiden flightThe maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot.
Flight engineerA flight engineer (FE), also sometimes called an air engineer, is the member of an aircraft's flight crew who monitors and operates its complex aircraft systems. In the early era of aviation, the position was sometimes referred to as the "air mechanic". Flight engineers can still be found on some larger fixed-wing airplanes and helicopters. A similar crew position exists on some spacecraft. In most modern aircraft, their complex systems are both monitored and adjusted by electronic microprocessors and computers, resulting in the elimination of the flight engineer's position.
Supercritical airfoilA supercritical aerofoil (supercritical airfoil in American English) is an airfoil designed primarily to delay the onset of wave drag in the transonic speed range. Supercritical airfoils are characterized by their flattened upper surface, highly cambered ("downward-curved") aft section, and larger leading-edge radius compared with NACA 6-series laminar airfoil shapes. Standard wing shapes are designed to create lower pressure over the top of the wing.
Pilot errorPilot error generally refers to an accident in which an action or decision made by the pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention defines the term "accident" as "an occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...
Fleet commonalityIn aviation, fleet commonality is the economic and logistic benefits of operating a standardized fleet of aircraft that share common parts, training requirements, or other characteristics. Commonality policies may be defined in a variety of ways, depending on the operator: for civilian aircraft: By model, same generation (e.g. Boeing "Next Generation" 737-700, 737-800, and 737-900) By model, different generations (e.g. Boeing's "Next Generation" 737-700 and 737 MAX-7) By family (e.g. Boeing 737) Between families (e.
Thrust reversalThrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing distances. Such devices affect the aircraft significantly and are considered important for safe operations by airlines. There have been accidents involving thrust reversal systems, including fatal ones.
Double-deck aircraftA double-deck aircraft has two decks for passengers; the second deck may be only a partial deck, and may be above or below the main deck. Most commercial aircraft have one passenger deck and one cargo deck for luggage and ULD containers, but a few have two decks for passengers, typically above or below a third deck for cargo. Many early flying boat airliners, such as the Boeing 314 Clipper and Short Sandringham, had two decks. Following World War II the Stratocruiser, a partially double-decked derivative of the B-29 Superfortress, became popular with airlines around the world.
