Flight Technical Error for Category B Non-Precision Approaches and MissedApproaches Using Non-Differential GPS for Course Guidance

摘要

Twelve general aviation pilots flew a Beechcraft Baron an 93 non-precisioninstrument approaches using a non-differential GPS receiver modified to satisfy selected functional requirements specified in TSO-C129. The purposes of the effort were to determine if the CDI sensitivity levels specified in the TSO were flyable by GA pilots and if flight technical error could be contained within trapezoids defined by TERPS criteria specified for approaches using off-site VORs. Pilots rated the sensitivity levels flyable, and flight technical error was well within VOR TERPS limits. Pilot performance during missed approaches, and the use of GPS in the terminal area during IFR and VFR operations were identified as areas requiring additional research.
