What is the maximum speed an airplane can go?
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
