Low-wing aircraft
As a low-wing aircraft are aircraft with the underside of the hull arranged wing designated (structural). The underside of the structure usually ends roughly with the underside of the fuselage. Particularly in the case of smaller aircraft with a small fuselage cross-section, the structure is more and more often passed under the fuselage so as not to lose any space. Typical aircraft are the Robin DR 400 Remorqueur light aircraft and the twin- engine passenger aircraft Airbus A320 .
When flying a low- wing aircraft close to the ground, the ground effect is more noticeable than with a shoulder - wing or high- wing aircraft of a comparable span, because the wing is closer to the ground. By the ground effect an airplane when can landing very long flatten out , what with short runways can be undesirable.
One advantage of low-wing planes is the better overview of the wings, e.g. B. during pre-flight checks and aircraft de-icing . In the case of engines mounted on the wings, their easier accessibility for maintenance and repairs is also cheaper, which starts with checking the oil level.
The construction of low-wing planes is easier because on the ground the weight of the wings presses directly on the landing gear and not additionally on the fuselage. This allows for lighter constructions and has resulted in the low-wing aircraft gaining acceptance in commercial aviation, with the exception of applications where landing on short runways is essential.
