The maximum detection range and the maximum recognition range air-to-ground and ground-to-air were determined. A Leopard tank, a radio truck, and a special test board were oberved from a Bell UH-1D helicopter and a Do 27 airplane. The maximum detection range ground-to-air was between 6 and 12 km larger than the maximum detection range air-to-ground. For the maximum detection range ground-to-air values between 9 and 16 km and for the maximum detection range air-to-ground values between 2 and 4 km were obtained. The maximum recognition range air-to-ground was up to 2 km smaller than the maximum detection range. At observation of the special test board the maximum detection range was smaller than the observation of the radio truck. The tests took place at horizontal standard visibilities between 36 and 57 km.
