To delay the stall to a higher lift coefficient, many airplanes are equipped with flaps (on the wing trailing edge), and a few designs use slats (on the wing leading edge) to further lower the stall speed. The following diagram illustrates the use of flaps and leading-edge slats to incre...
Coverts or Covert Feathers:Sets of feathers covering other feathers. For example, thewing-covertsare the feathers right above the wing feathers. They cover the base of the flight feathers to provide a smoother surface for the air to flow over. Undertail Coverts:Feathers around the vent Head ...

A triangular structure (ethmoidal notch) is located between the orbital plates, containing the crista galli of the ethmoid bone. The frontal bone articulates with the greater wing of the sphenoid posteriorly, which in turn articulates with the parietal bones. The most posterior bone is the ...

Flaps reduce the stalling speed of a wing at a given weight. The leading edge of the wings faces the front of the plane. Likewise, the trailing edge of the wing can be defined as the back edge that includes the aileron and trim tab. Some wings are fixed high on the plane above the...
