Used as a directional indicator the compass rose guides pilots flying test and experimental aircraft like the Pilatus PC-12 in the vast airspace over NASA’s Armstrong Flight Research Center in Edwards, California. This Pilatus PC-12 based out of NASA’s Glenn Research Center in Cleveland is being flown for a series of familiarization flights for NASA’s Armstrong pilots and crew. These familiarization flights supported communication, navigation and surveillance evaluations for Advanced Air Mobility research.
