This study assessed pilot-vehicle performance and workload associated with flying the Comanche Contact Analog, world-referenced primary flight symbology when compared with a conventional, screen-fixed, Compressed symbology. Previous investigation had revealed benefits when utilizing Compressed symbology in constrained flight maneuvers. The current evaluation further evaluated the effects of symbology by testing pilots in a high-fidelity simulator, executing more operational tasks. Flight performance and subjective ratings from six experimental test pilots were collected. Results replicated previous findings, and no performance differences were found in operational tasks. Pilot comments revealed significant preference for Compressed symbology, while some aspects of Contact Analog symbology raised objections. Performance, preference, and safety of flight issues perceived by test pilots merit a review of Contact Analog symbology design.
