Speed in a straight line with pre-stage


Speed in a straight line measures an object's ( aeroplane,helicopter, car or boat) speed over a specified distance in both directions. Normally you can do 2 runs in each direction to get the best speed in each direction, to get the average speed. The average speed is then published on this website. The difference from normal speed in a straight line is that you have to fly level for a specified distance (normally 100 meters) , before speed measurement starts. The difference in height from the first entry gate to the last camera may not be more that 15% or 4.5 meters over the 300 meter distance.
Speed measurement is done by camera, and the gate or area that you have to fly pass the camera to be registered is set to be a bottom distance 5 meters from the ground and the top distance 35 meters from the ground. The entry height and exit height should not be more than 4.5 meters in difference to make it a valid run.

Tips for gettting better speed with a flying object

Get maximum height (not exceeding your area's ceiling limit), before diving down and then enter the speed zone. While in the speed measuring zone, do not fiddle with the object because every movement translates to speed loss.

Error conditions

1. Missing the entry gate will cause the starting camera not to trigger. 2. Having an entry - exit height of more than 15% will invalidate the run.
