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.
The US spy plane, Lockheed U-2, has a top speed of 500 mph.
800mph
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
It depends what plane but it can reach approximately 900 KM/H

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.
The fastest commercial airplane is the airbus a380. The airbus a380 has a top speed of 634mph or 1020kph.
Cirrus SR22 flies with top speed of 405 kph.
From what i remember from my time doing some maintenance on these machines, the top speed was around 1,8 mach (times the speed of the sound) at an altitude (12km). But that was only with a sleek plane not carrying weapons.
The plane with the slowest max speed that was ever flown during WWI was the Bleriot XI, manufactured in france, and used primarly for Reconnaissance. It had a top speed of only 47 mph. The slowest American plane was the Aeromarine 40 Flying Boat Trainer Aircraft, with a top speed of 71 mph. The slowest aircraft actually used in battle was the Caproni Ca.1 Heavy Day Bomber, used in Italy, with a top speed of 75 mph. In America it was the Martin MB-1 / Glenn Martin Bomber Reconnaissance / Bomber Aircraft, with a top speed of 104 mph.
The top speed of an airplane can vary by the model of the plane. The highest speed ever reached was 2,193 miles per hour by an SR-71 Blackbird in 1976.
