The speed of sound measured at sea level is 661.47 knots.
The speed of light is about 900,000 times as fast as the speed of sound in air.
At the speed of sound
10mph wind speed is equal to 8.69 knots, or 16.1 km/h
If accelerating to the speed of sound, the subsonic.
Fast
4 knots top speed was 8 knots
Usual cruising speed was around 4 or 5 knots. Top speed was about 8. Remember that the speed varies according to the wind.
High Speed Cruise: 446 knots
Assume you want V2 speed. Set flaps 10. This should give you V1 of about 120 knots. Rotate at 140 knots and climb out at 148 knots.
Knots or Mach for very fast ones
About 20.5 knots, which is roughly equivalent to 23mph. Her maximum speed was 23 knots, about 27mph.
The speed of light is about 900,000 times as fast as the speed of sound in air.
At the speed of sound
It is slower than half the speed of sound.
160 knots or 185 miles per hour (max or "never exceed speed") this aircraft is not capable of this speed in level flight. The maximum speed in level flight is around 125 knots.
180 knots, below about 15,000 feet. 180 knots is the stalling speed for the F-16. It depends on your payload, and wind conditions to determine how fast you can go.
Captain Smith was going full speed , 24 knots
