Good luck.

Aircraft Detected
How does it work?
Aircraft detected speeding violations work by clocking the time it takes a vehicle to travel between two fixed points on the ground. Two marks are placed on the highway. One at the beginning and one at the end of a marked and measured area. A vehicle is observed first, to be travelling at a rate of speed higher than the surrounding traffic. Once the vehicle crosses the “beginning” mark, a stopwatch like device is triggered to measure time. When the vehicle crosses the “end” point, the time is switched off. Basically, the amount of time it takes to pass between the marks is calculated and an exact speed is immediately available.

Can it be inaccurate?
There are a few disadvantages to airplane speed detection, which can work to your benefit in court. Usually, the officer uses the airplane to pace the vehicle on the ground to obtain their speed. You can point out to the court that airplane speeds are measured in air speed, which is relative to the surrounding air. If the airplane is traveling into the wind, the speed is slower than if the aircraft was producing the same amount of power with a tailwind. It may be difficult to determine whether it was actually your vehicle that was spotted from the air, since many cars look alike from such a great distance.

Another problem is that this system relies on two different officers. Both officers need to be present in court for a conviction. If both officers show up at your hearing, you can request that one of them be removed so that each may be questioned individually. If their testimony contradicts one another, this may show cause for reasonable doubt.
