Wing Plan: The shape of the wing or wings of an aeroplane as seen from directly above or below.
Wing Tip: The outboard end of a wing. The shape of wing tips is important aerodynamically and in aircraft recognition.
[edit] Wing planform
The wing planform is the silhouette of the wing when viewed from above.

Rotary Wing Planform
Common terms used to describe the helicopter rotor system are shown here. Although there is some variation in systems between different aircraft, the terms shown are generally accepted by most manufacturers.
PA-28 Cherokees have stubby, constant-chord wing planforms similar in shape to another product with roots in Pennsylvania - the Hershey chocolate bar.
Full flaps with high-wing planes. Retractables, gear up. Low-wing with flaps up. Avoid the absolute full stall landing. Wings parallel to swell surface. Windshield may collapse; aircraft may skip or flip. Remain in crash position until motion stops.
ROGALLO WING - A flexible, delta-wing plan in which three rigid members are shaped in the form of an arrowhead and joined by a flexible fabric, which inflates upward under flight loads.
Others are wing planform (rectangular, tapered, etc.), wing tips, wing twist (we will discuss this topic, as it seems to be one that is frequently misunderstood or underestimated), wing aspect ratio, or span loading (which seems to be overestimated).
Curtis says a set of his original wing plans left his shop in a worker's lunch pail and shortly thereafter there were several other makes of Pitts wings available. The most commonly seen are from Sparcraft.
A stall should develop from the wing root to the tips so that if a wing drops, it will be relatively benign and the ailerons will be effective enough to help counter it (combined with coordinated rudder). Most General Aviation wing planforms are ...
The main planes of subsequent machines were strengthened, their span was reduced and blunter tips were fitted. A few of the early production aircraft, however, retained the wing plan of the first two prototypes.
