Extra weight (for example, carrying more cargo) increases the stalling speed, and a lower weight (e.g. minimum fuel) reduces it.
Depends on the airplane. A small Cessna might have a minimum speed of 40 mph, while a large passenger aircraft might have a minimum speed of 150mph or more. The actual speed for a given airplane will vary based on weight and flap configuration.
It increases.
Wing plays an important role in the speed of an airplane. A headwind reduces the speed of the aircraft. A tailwind increases the speed of the aircraft.
Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!
Assuming it as passenger aircraft and take-off speed = lift off speedwe have minimum runway length required as 80*35 = 2.8kmIf it is a military aircraft the length will reduce further to minimum unstick speed
By adding thrust to the engine or pitching downwards
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.
Aircraft speed and altitude cannot alter air pressure and how it complies with Bernoulli's principle. Aircraft speed decreases the pressure on the wings of the aircraft but this does not alter air pressure.
Unfortunately, this is much too general to answer. It completely depends on the type, manufacturer, and model of the aircraft.
Most aircraft have different landing angels dependent on weight, wing shape and stalling speed.
The lift off speed is dependant upon the weight of the aircraft. The heavier the aircraft the higher the speed. At maximum take off weight of 875,000 lbs (396,890 kgs) Vr (rotation speed) will be about 175 knots and V2 about 185 knots.
