A STALL, where the wing exceeds it's maximum angle of attack for the conditions (speed, g-force, etc>) under which the airplane is flying. Air separation over the top of the wing increases as angle of attack (angle of the wing compared to the airflow) increases, until the separation causes a decrease in lift. When under these conditions the amount of lift is less than the weight of the aircraft, the wing is stalled, and the aircraft descends. Since most aircraft don't seem to have an angle of attack meter, the airspeed indicator is usually marked with stall speeds experienced under various specific circumstances.

What causes loss of lift for airplanes?
There are a lot of factors that can cause the loss of lift in an aircraft, such as changing the shape of the airfoil, changing the speed, a change in air temperature which causes a change in air density, etc.
What is a loss of lift?
When a wing loses lift it "stalls".
What is a sudden and potentially dangerous loss of lift in an aircraft?
probably a stall, but they are not that dangerous, if you are trained to get out of them
What gives an airplane most of its lift?
if you mean, how does an airplane fly, then its because of the angle and shape of the wings. they have a certain tip upwards that keeps them in the air. The primary lifting force is generated aerodynamically by the airfoil of the wing. Some aircraft also have a fuselage which is designed to act as an airfoil. For example the Piaggio Avanti gets approximately 20% of its lift from the body of the aircraft, allowing it to have a shorter wingspan & higher top speed. In some rare cases the thrust of the engine exhaust may be vectored slightly to provide additional lift, the Mistubishi MU-2 uses its twin turbine engines in this way to achieve higher airspeeds at lower fuel costs. However, this method also makes the aircraft very difficult to handle in the event of an engine loss.
Why do elbows cause more friction loss in ductwork?
Elbows cause more friction loss in ductwork because elbows create resistance in the natural flow pattern of the air stream
What is a loss of lift that can cause an arcraft to crash?
If an airplane exceeds it's maximum angle of attack, or drops below a certain velocity aerodynamic STALL is what occurs. It is characterized by separation of the flow over the top surface of the wing. This phenomenon reduces lift which, if designed right, will cause the aircraft to nose dive. That being said, stall for most airplanes is really only dangerous during take off and landing since there's not much vertical space to recover from the sudden loss of lift.
Why do hot air balloons crash?
Any number of reasons: Loss of lift, weather, a rip in the balloon, wind, mountain's, powerpoles, general navigation mistakes, all can cause an accident.
What are the dangers of driving with a broken strut?
A broken strut can cause the tire to crash into the wheel well. This can cause loss of control of the vehicle and it can cause the axle to break.

What do you do to avoid a sudden loss of lift and settling of the airplane?
Do not exceed the critical angle of attack, basically the angle the wings make with the oncoming air as the plane moves forward.
What is a loss of lift?
When a wing loses lift it "stalls".
Why did the civilization crash before the renaissance?
Loss of the Roman empire
Why is wind shear dangerous to aircraft?
Wind shear, sometimes referred to as windshear or wind gradient, is a difference in wind speed and direction over a relatively short distance in the atmosphere. If the direction is downward, it can cause an abrupt drop in altitude for a plane before the pilot can compensate. Any sudden significant change in wind direction can cause a loss of control for an airplane, potentially causing it to crash. Some wind shear can be strong enough to cause structural damage to the aircraft.
Did speculation cause the Wall Street crash?
It was the main factor that made it happen, but there was many other reasons. Such as overproduction, unequal distribution of income, loss of export market ect.
Does nifedipin cause hair loss?
No nifedipine does not cause hair loss.
Can Syphillis cause hearing loss?
No, chlamydia does not cause hearing loss.
What diesies can an airplane cause?
It causes no diseases, but in the case of loss of cabin pressure you can get a cold or sinus infection. You have a small chance of getting vertigo. If anyone on the plane is sick, you can obviously catch their disease.
