Stalls occur when a wing's angle of attack is too large, surpassing some critical 'stall angle'. At this point, flow separates and the pressure differential on the bottom and top surfaces fails. Lift goes with it.
For a given weight (plane and cargo), the wings can provide sufficient lift through infinite combinations of angle of attack and velocity. As one goes down, the other must go up to compensate.
Since 'stall angle' goes down with velocity, however, there is a problem. There is some minimum velocity at which the angle of attack must be greater than 'stall angle' in order to produce lift, but being past this angle, it stalls and lift fails anyway. This velocity is called 'stall speed'.
Thus 'stall speed' is the absolute minimum speed a plane can fly at.

What is the stall speed of a 777?
The stall speed of an aircraft depends on its altitude, weight, configuration, and lateral and vertical acceleration. The stall speed for a 777 is dependent on these real-time factors.
What is groundspeed of the aircraft?
Ground speed is the speed the aircraft has compared to the ground. This is usually different from air speed, which is the aircraft's speed compared to the surrounding air. Thus an aircraft with 400 kph air speed and 50 kph headwind has a ground speed of 350 kph. For fun: with light aircraft with very low stall speeds it's possible to fly backwards (compared to the ground) if they fly into a headwind that's stronger than their lowest stall speed. I.e. their ground speed is negative.
Is 2.32 km in 10 mins good?
No, at that speed your combat aircraft will stall and come crashing down to the ground.
What is the stall speed of B777?
This varies with the weight of the aircraft, flap positions, weather conditions etc., but the stall speed of your average Boeing 777-200ER with a normal loading of passengers (about 300) on final approach would be around about 140mph.
What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
Why is landing speed of an aircraft high?
Beacuse if we cme with lower speed we can stall just at 50 ft,which is more than a danger..we come with speed so tht we can land with full control on aircraft coz more airflow more effective controls.
Can a four engine aeroplane be motionless mid air while all its engines are running?
In general, no. IF an aircraft had a headwind that was faster than the stall speed, it could in theory be motionless in regard to the ground- but the stall speed for most 4 engined aircraft is about 150 knots- that would be a VERY strong headwind. Flying into a hurricane might do it.
Is helicopter or aeroplane is having more speed?
An airplane has more speed due to the fact that helicopters airfoils (or blades) stall on one side once the aircraft's speed reaches the same speed of the rotor rpm.
What is the minimum speed of a Boeing 767?
The minimum speed of a Boeing 767 to remain in flight is about 160 miles per hour. Anything below that will cause the aircraft to begin to stall.
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.
Why does the aircraft stalls at a higher speed when the center of gravity is forward?
The plane stall because as much of the weight is on the nose, the nose moves downwards and you crash.
What are the best safe speds on maths in motion?
Assuming the question is about speeds, there is no simple answer. For example, a speed that is safe for a car on a winding road in wet weather would not be safe for an aircraft - the aircraft would probably stall!
