0 An aircraft's ground speed is its speed when measured against the ground rather than the air through which it moves.
The planned ground speed was 120 knots and the estimated ground speed at impact was 150 knots.
The aircraft crashed at a height of 812 feet at a ground speed of 151 knots, or 174 mph.
The aircraft then flared to an attitude of 30 degrees nose up, and finally impacted with a ground speed of 147 kts.
That works out at an average ground speed of 214 miles per hour.
The aircraft crashed at a height of 812 feet at a ground speed of 151 knots.
The aircraft crashed at a height of 812 ft, at a ground speed of 151 knots, or 174 mph.
It produced the wrong rotor speed, and it produced a ground speed during the final manoeuvre that was 11 knots higher than that measured by the ground-speed indicator.
In addition, grain damage can actually increase as the forward speed, or ground speed, of the machine is decreased.
