These are terms that aerospace engineers use to define the flight characteristics that is more associated with the Wing and not the airplane. The shape of a wing will produce different lift and drag for various flight conditions. One parameter is the Angle of Attack. This is the angle that the wing makes with the approaching air flow. A zero(0) Angle of Attack is when the nose of the wing is flying directly into the air flow. As the wing is turns the Nose up, this is a positive angle of attack and this generally results in an increase in Lift. Turning the wing in a nose DOWN is a negative angle of attack and reduces Lift or creates a negative Lift. If the Angle of Attack of the wing gets too large, the wing will stall. Stall occurs with the air flow over the wing is disrupted and does not flow smoothly over the wing. This reduces the Lift drastically. When an airplane pitches its nose up too much, the wing stalls and losses its lift and the airplane will begin to descend. Some airplanes will stall and one wing will drop over and the aircraft will go into a Spin. Modern airplanes, small ones and large passenger airplanes, are designed so that they easily stall into a spin.

What is the landing angle of an aircraft?
Most aircraft have different landing angels dependent on weight, wing shape and stalling speed.
What is a sudden and potentially dangerous loss of lift in an aircraft?
A sudden and potentially dangerous loss of lift in an aircraft is known as a stall. This occurs when the angle of attack is too high, causing the airflow over the wings to become disrupted and the aircraft to lose its ability to generate lift. It can lead to a loss of control and potential stalling of the aircraft.
What is the difference between the Angle of Attack and th Angle of Incidence?
Hi!The angle of incidence is built into the aircraft, and cannot be changed. This angle is the angle that the wing makes with a level surface (such as if the ground if the aircraft were parked).The angle of attack (commonly abbreviated AoA), is the angle that the chordline of the airfoil makes with the relative wind. So if you were in straight and level flight, maintaining altitude, the angle of attack would be zero degrees.When an aircraft exceeds a critical angle of attack (which is determined by the design of the airplane), the airflow will peel off of the wing, causing the wing to stop producing lift. The aircraft is, in this scenario, stalled.Hope this helps.Source(s):PPL ASEL 6/17/08
What is the angle between the airplanes wing and the direction of airflow called?
The angle between the airplane's wing and the direction of airflow is called the angle of attack. This angle is important for generating lift and controlling the aircraft's flight.
What is the angle of attack on an airplane?
The angle of attack is an aerodynamic term which refers to the angle between the mean wing chord of the airfoil and the direction of airflow. This is different from the pitch angle of the aircraft in that the pitch angle refers to the aircrafts position in relation to the horizon, whereas angle of attack refers to the aircrafts angle in relation to airflow.
What is the difference between angle of attack and positive angle of attack?
Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow. If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.
Relation between aspect ratio and stalling speed?
wings with smaller aspect ratio stall at higher angle of attack .. and wings with larger aspect ratio stall at a lower angle of attack ... stall can take place at any air speed but only a specific angle of attack.. my view says aspect ratio has no relation to stall speed.
What is the function of slats in aircraft?
Slats are used to reconfigure the wing in a high speed, or high angle-of-attack maneuover. When the units of angle of attack increase, the wing chord decreases. Slats compensate for this occurance.
What is the best angle of attack for a kite?
The best angle of attack for a kite typically ranges from 5 to 15 degrees, depending on the kite's design and the wind conditions. This angle allows the kite to generate lift while maintaining stability and control. In lighter winds, a slightly higher angle may be beneficial, while stronger winds may require a lower angle to prevent stalling. Adjusting the angle of attack can help optimize performance and maneuverability.
The upward angle of the wing is called the?
The upward angle of the wing of an aircraft is the dihedral angle. It is vital because it keeps the plane from unexpectedly rolling while in flight.
What is the difference between angle of incidence and angle if attack?
The angle of incidence is the angle between a reference line, usually the chord line of a wing, and the oncoming airflow or relative wind. In contrast, the angle of attack is the angle between the chord line of a wing and the direction of the resultant lift vector. While the angle of incidence is a fixed design feature of the aircraft, the angle of attack can vary during flight and is crucial for determining lift and stall conditions.
