What should be the deflection of the flaps during takeoff?

The amount of flap used on takeoff is specific to each type of aircraft, and the manufacturer will suggest limits and may indicate the reduction in climb rate to be expected. The Cessna 172S Pilot Operating Handbook generally recommends 10° of flaps on takeoff, especially when the ground is rough or soft.

How do flaps affect angle of climb?

The flap setting also affects the climb gradient. Increasing the flap angle increases the drag, and so reduces the climb gradient for a given aircraft mass.

Do flaps increase angle of climb?

Angle of climb is essentially a matter of how slowly you can fly, other things being equal; and so a flap setting that lowers stalling speed without disproportionately increasing drag will allow an airplane to climb at a steeper angle. Flaps do increase drag, and the more you deflect them the more drag you get.

When the trailing edge flaps are lowered?

Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift. In addition, the large aft-projected area of the flap increases the drag of the aircraft. This helps the airplane slow down for landing.

Why do trailing edge flaps increase the critical angle of attack?

So from my understanding, trailing edge (TE) flaps increase wing area + camber, effectively increasing the coefficient of lift for a fixed AOA which leads to higher lift at a fixed airspeed and AOA. This allows an airplane to fly at lower speeds + lower AOA to maintain lift.

What is the bending angle of a flap?

The trailing edge of the flap bends flexibly starting at 50%. Here, δangle is the bending angle of the flap, cflap is its chord length, and O/L is the overlap between the main wing and the flap; gap refers to the width of seam, and δ is the deflection angle of the flap. Fig. 1.

Is there a trailing edge flap on an airplane?

There are many variations of trailing edge flap in use on modern aircraft today. Plain or simple flaps merely deflect the trailing edge region downward to increase camber.

Why is the trailing edge of a wing hinged?

[Figure 1-63A] The airflow over the wing continues over the upper and lower surfaces of the flap, making the trailing edge of the flap essentially the trailing edge of the wing. The plain flap is hinged so that the trailing edge can be lowered. This increases wing camber and provides greater lift.
