The target speeds were set at 225 mph.
The national speed limit is not a target speed.
This combination places the true target speed at 1,400MPH (2x6+2 or 2x5+4).
Radar and sonar systems use the same phenomenon to detect target speed.
By late 1939, when the project was finished, the target speed was a much higher 750 km/h (465 mph).
The boat accelerates at a moderate pace until the target speed is reached, somewhere between 9 to 12 miles per hour.
In the cab, the driver has a consolidated display which displays the train's target speed and other useful operating information.
In some cases, such as with submarines, the target speed could be estimated using sonar data.
The permitted speed range covering these target speeds is 25 to 85 km/h.
International targets are also thrown a longer distance from similar heights (over 70 yards), resulting in a faster target speed.
