Cessna flaps v's Piper PA-28
W2k The flaps on the Cessna 152 are totally different to those on the PA-28. The Cessna uses a Fowler type slotted flap in that they initially move more 'aft' than 'down' on initial movement to 10 degrees, which effectively increases the wing area, and then move progressively more 'down' than 'aft' as the profile of the flap tracks dictate to 30 degrees. The PA-28 on the other hand is a hinged slotted type flap which simply moves from a flap up to flap down position with no aft movement, thus no increase in wing area.
