How often do AWACS planes dump kerosene over the Schinveld woodlands?

Never. AWACS aircraft do not dump any kerosene over the Schinveld woodlands and have never done so. Kerosene discharge is an emergency procedure used by either civil or military aircraft in extreme situations when they have to land immediately and are still too heavy to be able to do this safely. In such cases, after obtaining permission from the air traffic control authority, the pilot can lighten the airplane by discharging kerosene at high altitude and within a designated zone of the airspace. This exceptional measure is not used recklessly in either military or civil aviation, and certainly not during the landing itself.
