Angle of attack
The angle of attack is the angle between the chord line of an airfoil and the direction in which the aircraft is moving (relative wind).

The is defined as the angle between the plane of the wing (airfoil
chord) and the direction of motion (free stream velocity).

is a very important and useful concept. Most of the airplane's critical performance numbers are more closely related to than to anything else. Let's explore what this means.
Angle of Attack, (AOA)
Definition: The angle of attack is the angle between the chord of the airfoil (determined by wing form) and the incoming relative wind.

The Effect of Roll on the Angle of Attack
It is a widely accepted that the angle of attack increases when a wing drops while the angle of attack decreases when a wing rises, but this is rarely explained.

Angle of Attack The amount of pitch at which an airfoil is flying. By adjusting the angle of attack, the efficiency of the wing/blade is effected. More precisely, the angle between the chord of an airfoil and the wind.

ANGLE OF ATTACK - Angle at which the air-stream meets an aerofoil surface.

The angle that the wing penetrates the air. As the increases so does lift, up to a point (and drag).
The angle of attack of the tail rotor is controlled by the pilot's anti-torque pedals (they're not "rudder pedals" in a helicopter). The pedals are typically connected to the pitch change mechanism by either push pull tubes, or by cables.
When is increased:
upper surface lift increases relative to the lower surface force. Since the two vectors are not located at the same point along the chord line, a twisting force is exerted about the center of pressure.

When the is less than the stalling angle, any increase in causes an increase in lift coefficient that causes the wing to rise.
So, what angle of attack do we hold and how do we measure it? The answers are, we don’t know what angle of attack is needed and we have no accurate way of measuring it.
On the Trim panel you can select to have the program compute the trimmed or your can input your own flight by using the drop menu at the upper right.
Because the angle of attack is relatively high, the airspeed is relatively slow, and the power setting is high, the airplane will have a tendency to roll and yaw to the left due to turning tendencies created by the rotating propeller.
During this training, the flight instructor should emphasize that the direct cause of every stall is an excessive .

To achieve this high angle of attack, the fuselage geometry must allow ground clearance at take off and on landing (see figure 2).
