The preliminary report says the small plane was too heavy for conditions that cause icing at the speed and altitude it was ...

The pilot handbook also indicates an air speed of 95 knots must be maintained ... the pilot was told to descend to 4,000 feet (1,219 meters) at his discretion, the autopilot disengaged at 99 ...

To give a better idea, the helicopter was on the ramp while we were walking around the static S-97 in the hangar, about 50 meters away ... forward to increase airspeed, using the main rotors ...

At 14:12:01, the CRJ900 descended through 500 feet (152.4 meters) above ground level (AGL) with an indicated airspeed of 150 kn and a ground speed of 121 kn. The engine thrust was at around 64% N1 ...

So, answering the main question here, the “airspeed velocity” of an unladen swallow (European) is something like 20.1 miles per hour (32.4 kph) or 29.5 feet per second (9 meters per second).

Although it achieved the first ascent of a vertical-flight aircraft with a pilot, it only reached a height of 0.6 meters ... to control altitude and airspeed; gyroscopes controlled yaw and ...
