What is Angle of attack and stalling in aircraft?
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 can immediately rob an aircraft of all forward airspeed and lift resulting in uncontrolled descents?
That would be a wing stall, or just, 'stall'. This kind of stall has nothing to do with the aircraft's engine, if it has one.
What causes the separation of air over the wing during a stall?
The angle between the chord of the wing and the longitudinal axis of the airplance is too great.

What is stall of an aircraft?
Answer 1As an airplane's wing moves through the air, the faster moving air on the top of the wing creates a low pressure zone or "lift" which keeps the airplane up and flying. If anything happens to deflect or destroy that proper airflow (smooth flow of air around the wing) the wing loses lift, and is said to stall.This could be from loss of speed or too much angle of attack (pulling back to hard)In many cases the actual stall is preceded by a buffet (shaking) In Many cases you can avoid the stall by lowering the nose of the aircraft.A spin is an aggravated stallYes that is true but another reason an aircraft could stall is because the service celing of the aircraft has been reached the aircraft can no longer produce enough thrust to keep it in the air because the air is too thin or the engines aren't strong enough
What causes an aircraft to stall?
The stalling of an aircraft wing is caused by the disruption of the airflow on the upper and lower surfaces of the wing, An airflow is travelling fast enough over a wing. A low pressure area develops on the underside of the wing and a very high pressure on the upper surface of the wing ......This is what causes lift- the force that allows the aircraft to fly. If this airflow is Broken or reaches a speed too slow to maintain the low pressure required to create the lift. The wing will stall
What is the disadvantage of swept back wing?
The surface area of the wing is slightly reduced, resulting in a reduced ability to generate lift. The effective aspect ratio is reduced, helping to increase wing tip vortices. Also, it is harder to recover from a stall with a swept wing aircraft, as the rear of the wing tends to stall first. This produces a greater nose up pitch on stalling, which is far harder to recover from than with a straight-winged aircraft.
What will the angle of attack at which an airplane wing stalls at is do to what?
The plane stall remain the same regardless of gross weight.
What is compressor stall about wing?
Compressor stall and a wing stall are different and unrelated. Compressor stall refers to the compressor section of a jet engine. The compressor section is comprised of several spinning round discs attached to a shaft that runs through the engine. Blades attached to each disc compress the intake air, which is later mixed with fuel and burned in the combustion chamber. If the intake flow of air is disrupted, compressor stall can occur, allowing high pressure gasses to move forward through the engine, making a loud banging noise. Compressor stalls are usually momentary and do not cause any damage or significant reduction in power. A wing stalls when the angle between the chord of the wing and the relative wind becomes excessive and the airflow over the top of the wing is disrupted. The disruption results in a sudden loss of lift and the aircraft will descend and may become uncontrollable.
The similarity of the characteristics of sheep and reindeer is due tohen their having a common ancestor This sort of phenomenon is called?
Homologous characteristics (as opposed to analogous characteristics, eg a bats wing and a birds wing). So I guess its called homology?
How manufacturer selects the wing on aircraft?
It is based on the aerodynamics of the wing. The engineers will select the best wing that fits the main mission of the aircraft they are building in order to take full advantage of the wing. Some wings are more efficient when flying slow and some are better when flying fast. Wings that help you go fast tend to stall sooner when flying slow than wings that help you go slow for example.
How fast can a jet plane travel per hour at slow speed?
It depends on weight, wing span stall speed
