Piper PA28R-201-Arrow III. at Halfpennygreen Airfield Bobbington, West Midlands. England. SCO 8879
For the Cherokee family, Piper used their traditional flight control configuration. The horizontal tail is a stabilator with an antiservo tab (sometimes termed an antibalance tab). The antiservo tab moves in the same direction of the stabilator movement, making pitch control "heavier" as the stabilator moves out of the trimmed position. Flaps can extend up to 40°, but are considerably smaller, and arguably less effective, than the flaps on a Cessna 172. Normally, 25° flaps are used for a short- or soft-field takeoff. The ailerons, flaps, stabilator, and stabilator trim are all controlled using cables and pulleys. In the cockpit, all Cherokees use control yokes rather than sticks, together with rudder pedals. The pilot operates the flaps manually using a Johnson bar located between the front seats: for zero degrees the lever is flat against the floor and is pulled up to select the detent positions of 10°, 25° and 40° All Cherokees have a brake lever under the pilot side of the instrument panel. Differential toe brakes on the rudder pedals were an optional add-on for earlier Cherokees, and became standard with later models. Cherokees normally include a rudder trim knob, which actually controls a set of springs acting on the rudder pedals rather than an external trim tab on the rudder — in other words, the surface is trimmed by control tension rather than aerodynamically.
