150 Plain flaps are the simplest type of flap. It is simply control surface that pivots down, producing some extra lift and bit of drag.
151 Slotted flaps are a more effective type of flap. A 'slot' (or gap) between the flap and the wing SPEEDS THE AIR UP AS IT PASSES OVER THE FLAP, producing more lift. The wing pitches down more, though.
152 Slotted Fowler flaps move BACK AND DOWN when deployed. A 'slot' along the flap SPEEDS THE AIR UP OVER THE TOP OF THE FLAP, and keeps it from stalling as well, producing lots of extra lift.
153 Slotted Double-Fowler flaps moves BACK AND DOWN when deployed. Multiple 'slots' along the flap SPEED THE AIR UP OVER THE TOP OF THE FLAP, and keep it from stalling as well, producing lots of extra lift.
154 Slotted Triple-Fowler flaps moves BACK AND DOWN when deployed. Multiple 'slots' along the flap SPEED THE AIR UP OVER THE TOP OF THE FLAP, and keep it from stalling as well, producing lots of extra lift.
155 Split flaps lower the bottom surface of the wing, but the top surface of the wing remains stationary! This produces a high-drag 'wedge'. You get lots of lift, but tons of drag!
305 A Krueger flap extends out of the LEADING EDGE of the wing to manage the airflow to delay the onset of a stall, allowing slower flight at higher angles of attack without stalling.
306 A slat extends forwards out of the LEADING EDGE of the wing to manage the airflow and form a slot to allow hi-energy air to flow through it to delay the onset of a stall, allowing slower flight at higher angles of attack without stalling.
156 flap root chord ratio| { This is the fraction of the total wing CHORD (from leading-edge to trailing-edge) taken up by the flap. THIS IS THE CHORD RATIO AT THE ROOT EDGE OF THE CONTROL.
536 flap tip chord ratio| { This is the fraction of the total wing CHORD (from leading-edge to trailing-edge) taken up by the flap. THIS IS THE CHORD RATIO AT THE TIP EDGE OF THE CONTROL.
157 flap Cl| { This is the flap's increment of coefficient of lift at max flap deflection FOR THE INFINITE-WING CASE, Finite-wing effects will be applied.
158 flap Cd| { This is the flap's increment of coefficient of PARASITE drag at max flap deflection FOR THE INFINITE-WING CASE, Finite-wing effects will be applied.
159 flap Cm| { This is the flap's increment of coefficient of moment at max flap deflection FOR THE INFINITE-WING CASE, Finite-wing effects will be applied.
165 flap detents| { This is the number of detents (stop-points) in the flap deflection cycle.
160 flap def time|(sec) { This is the time required (in seconds) to go from retracted to full flaps.
161 min flap to engage flap blowing|(rat) { This is the minimum flap deflection (in ratio to full) at which engine air will be blown over the part of the wing that has flaps. Blowing will be DIS-engaged at smaller flap deflections, and progressively ENGAGE at higher flap deflections until full engagement at full flaps.
162 thrust diversion|(part) { This is the part reduction in the effective engine throttle when the flaps are lowered, caused by bleeding air off the engine to blow over the flaps.
163 flap speed increase|(kt) { This is the speed added to the entire part of the wing that has flaps or other controls when the flaps are deployed and the engine is at full throttle. This speed ramps up directly with throttle, and phases in with flap deflection. This number is ZERO unless you have blown flaps, which blow engine bleed-air over the flaps. Remember that propwash is already simulated by X-Plane, and need not be added here!
328 Blow ALL flight controls, not just the flaps.|Do this for low-speed control. { Once you get too slow, the flight controls are not effective enough to fly... so duct air over them too!
164 increase in stall angle from L.E.D. deployment|(deg) { Slats allow the wing to go to a higher angle of attack without stalling (running out of lift). Slats may allow the wing to gain an additional 8 degrees of angle of attack without stalling.

168 |-le train dirige { This indicates whether a streamlined wheel fairing is over the gear, which will signifigantly reduce the drag of the landing gear. This will have some impact on the pitch-down moment from having drag below the centerline, a well as the overall drag on the craft.
