If possible one drop run should be made using two message drop containers. Two targets may be utilized; one located near the approach end of the runway and the other near the departure end. The total distance from the drop container to the target will be measured in feet. The lowest total distance for the two containers will determine the winner. No mechanical or electronic devices may be used for dropping the containers or for calibrating the time of release. Power shall be reduced on the downwind leg and the turn onto final approach shall be completed above 300 feet AGL. The drop run shall be made generally into the wind at normal cruising speed. Flaps and landing gear (if applicable) must be fully retracted. Proper spacing in the pattern shall be maintained by each aircraft. If proper spacing cannot be maintained, the overtaking airplane shall make a go-around. The drop run over each target shall be counted whether the container is dropped or not.
