Flaps

Aviation  Flaperon  Flare

Flaps are hinged surfaces that are usually located on the trailing edge of the wings on fixed-wing aircraft and are used for various purposes. Flaps that are located on the leading edge of the wings are known as slats and/or Krueger flaps.


Split flaps are more useful for landing, but the partially deflected hinge flaps have the advantage in takeoff. The split flap has significant drag at small deflections, whereas the hinge flap does not because airflow remains 'attached' to the flap.

Flaps and landing gear
Extending the flaps will decrease the climb performance as L/D ratio is less and the power required increased. The best rate-of-climb and angle-of-climb is always reached with flaps up.

COWL FLAPS & ENGINE COOLING
PURPOSE OF THIS MANUAL
The purpose of this manual is to advise simulator pilots of some of the ways cowl flaps and other devices are used to cool piston-powered aircraft engines.

Landing Flaps
Technology / Aviation / Landing Flaps: a secondary control surface built into the wing by which the overall wing area, or lift-drag ratio, can be increased. The increased wing area permits a slower landing speed.

Flaps
Hinged surfaces attached to the trailing edge of a wing, either to increase manoeuvrability (as on a control line aerobatic model) or to increase lift at the expense of drag (as on most full size aircraft and some radio control aeroplanes).

Flaps Parts of the wings that can be extended to help slow the plane for landing and increase lift at low speeds. Full flaps are typically used for landing, and partial flaps may also be used for takeoff.

Flaps
Each half of wing is equipped with the split flap that takes about two thirds of half span of wing. The rectangular flap consists of ribs and skin, creating cavity. The flap is hinged on the wing by means of swivel throughout its length.

Flaps Hinged control surface located at the trailing edge of the wing inboard of the ailerons. The flaps are lowered to produce more aerodynamic lift from the wing, allowing a slower takeoff and landing speed.

FLAPS Hinged surfaces on the inboard rear of wings, deployed to increase wing curvature (and thus, lift), primarily used to control angle of descent and to decrease landing touchdown speeds.

Flaps
Control surfaces installed on the trailing edge of a wing and used to increase the amount of lift generated by the wing at slower speeds. Flaps also have the effect of slowing an aircraft during its landing approach.

F
flaps
Hinged portions of the wing that act together to increase the lift characteristics of the wing. Most often used to allow slower landings, and shorter takeoffs. Not present in most aerobatic aircraft.

* Flaps for Normal Takeoff
Extending the flaps for takeoff will improve your ability to see over the nose. This is because it increases the incidence; therefore the airplane will fly at a lower pitch attitude (for any given angle of attack).

Use flaps to help control glide slope
Configuration changes don't require power to control glide slope. Stay a little high and let the flaps bring you down.

Flaps up, power-on stalls were hardly more dramatic. The J230 got wobbly sooner without flaps, at around 58 knots indicated, and the nose angle was higher.

Flaps are airfoils on the trailing edge of the wing. In normal flight they are at 0, and act simply as part of the wing.

Flaps (often confused with any of the other moveable surfaces) are used on wings to increase lift and/or increase drag as an aircraft flies progressively slower.

Flaps, Ailerons, and Flaperons
Full span ailerons, which also act as full span flaps, are thus used (called flaperons).

BLOWN FLAPS - Aerodynamic surface over which bleed air is discharged at high speed to prevent breakaway of the normal airflow.

BOUNDARY LAYER - Thin stratum of air nearest to an aircraft's external surface structure.

Split flaps, although quite effective, have fallen out of fashion and will not be discussed further [though I have re-introduced them with the ZENITH CH 2000].

April 2 - Northwest Orient Airlines Flight 2, a Boeing Stratocruiser, ditched into Puget Sound after takeoff from Seattle-Tacoma International Airport after the cowl flaps were incorrectly set for takeoff.

VSO: stalling speed at MTWA, in landing configuration with flaps and landing gear down, at sea level, ISA conditions (bottom of white arc on ASI).
VX: best angle of climb speed on all engines.
VXSE: best engine-out angle of climb speed.

Designer Itokawa turned to a sophisticated flight control technology in the form of "butterfly shaped (actually paddle shaped) air combat maneuvering flaps" that were deployed from Bowden levers atop the control stick (like the brake on a Nanchang) ...

Takeoffs normally are done with flaps retracted. To reduce takeoff distances for short- and soft-field departures, Piper recommends that the flaps be set at 25 degrees and the nose lifted at a lower airspeed.

When one blade flaps up, the other flaps down. The entire mechanical arrangement works like a child's see-saw (teeter-totter) toy.

The description optionally includes leading-edge slats, flaps on inboard trailing-edges and trim tabs, all of which are mentioned separately, if installed.

One way to cut the speed reduction somewhat is to land without flaps or with partial flaps. Recalling that the best approach speed is 1.3 times Vso, raising Vso means you can land faster and still be within acceptable parameters.
