| Abstract | This report documents the flight test results of the optical infrared (IR) Pilot Warning Instrument (PWI) system conducted by the Transportation Systems Center as part of an FAA/NASA PWI development program. The test program is described and the flight test data presented. The data is analyzed and used to calibrate a model that is developed to characterize the system performance. The cumulative probability of detection versus range for a given system threshold is calculated and compared with the PWI performance specification defined by the Collision Prevention Advisory Group (COPAG). The comparison indicates that the Optical IR PWI system tested met the COPAG specifications for a detection likelihood of 95% for a 1 nmi range for an appreciable fraction of the testing time. Even under the worst testing conditions encountered, the range at which this detection likelihood occured was sufficiently large to demonstrate feasibility and to recommend a continuation of the development effort for this approach. A series of recommendations for improving system performance and obtaining additional information needed to characterize that performance are included. |
