Q

Why does RJ have high wings?

A
  1. The uninterrupted high wing produced 4% more lift.
  2. It keeps the engines clear of the ground reducing the chance of the engine ingesting debris or sand
    etc.
  3. The high wing allows the flaps the fit snugly with the fuselage so lift efficiency it improved.
  4. Finally because the engines are suspended from pylons it keeps the engines efflux clear of the flaps.
