The US spy plane, Lockheed U-2, has a top speed of 500 mph.
800mph
The fastest commercial airplane is the airbus a380. The airbus a380 has a top speed of 634mph or 1020kph.
Maximum speed of piston engine plane is about 500 km per hour.
The Concord's speed was 1,176. Faster than the speed of sound
You can have a top speed and you can have an average speed, but you can't have a top average. Top average is like saying exactly approximately. Leaving that it's very much dependent on the type of aeroplane. The first planes weren't faster than scooters, while today fighter aircraft will easily do twice the speed of sound. Pick a plane type and vintage first, then you can find out how fast it can go.
It is a really fast fighter plane and can go to speeds up to 3 times the speed of sound! It will travel around 1000 meters per second at it's top speed.
The speediest plane I have ever witnessed was the Boeing X-51 WaveRider which can run at up to Mach 5, which is 5 times the speed of sound.
It depends what plane but it can reach approximately 900 KM/H
It depends what plane but it can reach approximately 900 KM/H
This question really depends on what type of plane you mean, I will answer Commercial planes for everyday peopleThe speed of light is approximately 186,000 miles a second or 669600000 mph / 299,792,458 meters per second.A commercial plane like a 747 passenger plane that you might use to go on holiday travels at around 800mph. (top speed)669600000mph (speed of light) - 800mph (average plane speed) = 669599200.The speed light is roughly 669599200MPH faster.According to relativity, the speed of light is precisely the speed of light faster than a plane, to the observers in the plane. The above answer is only correct for an outside observer in a particular reference frame.
.... about 400 km/h if it is ejected from a transport plane at 6000 feet.... Top speed of a "Smart" is officially 145 km/h www.smart.com
