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

Angle of attack is a very important and useful concept. Most of the airplane's critical performance numbers are more closely related to angle of attack 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 acute angle formed between the chord line of an airfoil and the direction of the air striking the airfoil.
Anti-ice. Preventing the accumulation of ice on an aircraft structure via a system designed for that purpose.
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
The angle that the wing penetrates the air. As the angle of attack 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 angle of attack 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 angle of attack is less than the stalling angle, any increase in angle of attack 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 angle of attack or your can input your own flight angle of attack 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 angle of attack.
They observed an interesting maneuver employed by a pigeon which seemed to secure its lateral balance in exactly the way they wanted; this bird was seen to give its two wings each a different angle of attack -~ whereat one wing would lift more ...
Leading edge slats prevent the stall up to approximately 30 degrees incidence (angle of attack) by picking up a lot of air from below, where the slot is large (Figure 3), ...
To achieve this high angle of attack, the fuselage geometry must allow ground clearance at take off and on landing (see figure 2).
The elevators control the angle of attack of the wings. When back pressure is applied on the control wheel, the tail lowers and the nose raises, increasing the angle of attack.
The elevator! Controller of so many things: angle of attack, airspeed, G-load, stalling, turning and whether or not we end up breaking the airplane, too. So fundamental, yet so often omitted during normal flight training.
Results when a wing exceeds its angle of attack (angle between airfoil and relative flow of wind), the airflow is disrupted, and the wing no longer produces lift, with sudden drop and possible loss of control.
That oscillation is called a phugoid. Angle of attack stays near-constant, but pitch varies because the airspeed and altitude are constantly interchanging until balance is regained.

Angle of sideslip ...
Small, aerodynamic surfaces on the leading edge of the wings of fixed aircraft which, when deployed, allow the wing to operate at a higher angle of attack.
Occurs when lift-producing airflow over the wings is disrupted or lost because angle of wings to airflow (angle of attack) is too high. Most commonly occurs when a pilot doesn't maintain sufficient airspeed in a climb or turn.
A tail surface that acts as both stabilizer and control surface. The moveable surface can minimize the local angle of attack, so this form of tail surface is considered to be less susceptible to tail stall than a standard horizontal stabilizer.
A measure of the degree to which an aircraft's nose tilts up or down. Also a measure of the angle of attack of a propeller.

The tail fin determines the directional stability.
If a gust of wind strikes the aircraft from the right it will be in a slip and the fin
will get an angle of attack causing the aircraft to yaw until the slip is eliminated.
In this scenario you are well behind the Ontario glider (second of the oversize drones), and overtaking it. In this con-figuration it offers you the minimum target surface, so you may want to change your angle of attack.
Stall - A loss of lift when the angle of attack increases to a point where the flow of air breaks away from a wing or airfoil, causing the wing to drop.
