MonoplaneA monoplane is an aircraft with one main wing or pair of main wings, in contrast to a biplane or triplane.
The main distinction in types of monoplane is how the wings attach to the fuselage:
- low-wing, wing lower surface level with bottom of fuselage;
- mid-wing, wing mounted mid-way up fuselage;
- shoulder-wing, wing mounted above fuselage middle (rare);
- high-wing, wing upper surface level with top of fuselage;
- parasol, wing mounted above fuselage (now rare).
Although they are now the norm, the popularity of monoplanes has varied through the history of flight.
