This is known as the "never exceed" speed or VNE and is represented by a red line on the airspeed indicator.
It is 583 miles per hour!
That is it's maximum speed. Different for every aircraft.
Unfortunately, this is much too general to answer. It completely depends on the type, manufacturer, and model of the aircraft.
The maximum speed a airplane can go is a factor of it drag and trust. All planes have a Vne speed witch is the never exceed speed, which is were the amount of drag becomes so great that it will start to damage the aircraft. Many factors have play on this number, such as the camber of the wing, form drag, induced drag, and how strong the frame is. A C-173 Vne is 169, and a SR-22 can go muck 3 or 4. Maximum speed of a airplane is around 1000 km per hour
Every aircraft has a different height, and there are so many it is impossible to say an average speed. Most airliners cruise around 580-640 mph.
The Cirrus SR 22 has a max speed of 183 knots. That's pretty good for a small private aircraft.
Augmented maximum mechanism or in simple term after burner is incorporated to high speeds.
The E1 series high-speed train type had a maximum rated speed of 240 kph (~150 mph). They were operated by East Japan Railway Company (JR East) from July 1994 until September 2012.
Possibly around 90 mph on a flat smooth road.
Airflow ans lift over the airframe is affected by the airplane's speed.
The E1 series high-speed train type had a maximum rated speed of 240 kph (~150 mph). They were operated by East Japan Railway Company (JR East) from July 1994 until September 2012.
The British Aerospace Sea Harrier FA2 variant can reach a maximum speed of 735mph; other variants are slightly slower.
