Why wings of Propeller or turboprop aircraft are located on the upper side of the fuselage?

Answer 1

It's not true that all the propeller driven aircrafts are high wing (i. e. with wings above the fuselage). There are well known examples of propeller aircrafts which were low wing (i.e. with wings below the fuselage), like DC-3 Dakota, Super Constellation, etc.

Answer 2

One reason, is so that the pilot is able to see more of what is under the craft than if the wing were attached to the underside of the fuselage, as is the case with most WWII combat fighters.

Another is that with the fuselage hanging from the wings instead of pushing down upon the wings, even if the craft is improperly balanced from nose to tail, the craft can still maintain an upright flying position when the controls are completely released, whereas WWII fighter pilots almost ALWAYS had to keep a hand on their controls to keep from pitching into a dive or to keep from pitching up, losing airspeed, and stalling, into a dive.

So, I guess both of my reasons could be summed up as being for safety.

Answer 3

One reason for this very simple - it prevents the propellors hitting the ground in a hard landing. It may also assist in take-off - reducing turbulence under the aircraft.

Answer 4

not necessarily, their are "low wing" and "High Wing" aircraft, if you mean "Why is it forward toward the nose of the aircraft", it is because, the smaller wing in the rear balances the science of "Flight".
