'slit t :.king any calculAtions, Messrs could not say whether the radar system old be used 4nd still newt the weight and size require ttsss of the aircraft and ground equipments, They were sure, however1 that the - radar awe would it give the required range, of 15 miles, but agreed to determine the get the repaired range of 15 mile,, the Arc system would have to be used against a radio transmitter on ground, This would allow the aircraft to approach the DZ area,then the radar system would give accurate (within less than one foot) range and azimuth the final approach. The coWlwto beacon system ,rout then consist of two independent systems, (1) :~ ground trans- sitter the sircraft'ss and (2) a corner reflector on the cround and the miniature s device in the aircraft. 4.
