When the FAA approved Ransom's plan, the DHC-7 was able to conduct Day and Night VFR "STUB" operations by landing on one of the crossing runways, proving to the FAA that the airplane was capable of landing and holding short of the active runway. The DHC-7 was also able to demonstrate that it was capable of making a VFR approach to the stub runway, losing one engine and then turning sharply away and exiting the area with only 3 engines operating, and never violating the active runway's protected airspace.
