The F-18 by McDonnell Douglas is a twin-engine multi-role combat aircraft. It was developed in the 1970s and since 1983 it is in use. The F-18C of the Swiss Army is single-seated, as F-18D it exists also as two seated version. The two turbines give enormous performance of the machine. Thus, climbs of up to 50000 ft/min and a maximum speed at optimum altitude of Mach 1.8 are possible. The machine is controlled electronically by a fly by wire system. In order to increase the maneuverability, the machine was designed in a way that a control without this electronic support is not possible.
