Final Phase Runway Visual Range Rvr Automated Surface Observing System Asos Interface Operational Test And Evaluation Ot E Report

This report summarizes results of Operational Test and Evaluation (OT & E) performed on the Final Phase Runway Visual Range (RVR) Automated Surface Observing System (ASOS) Interface. Testing was conducted from June 23 through 27, 1997, at Memphis International Airport (MEM). This test effort follows two OT & E sessions for the Interim Phase RVR/ASOS Interface at MEM during October 1996, and January 1997. Refer to document DOT/FAA/CT-TN97/14 for results of OT & E on the Interim RVR/ASOS Interface. The purpose of OT & E was to verify adherence to requirements as stated in Interface Control Document (ICD) 50-SANW-1-0050 and determine the operational effectiveness and suitability of the interface within the National Airspace System (NAS). OT & E activities resulted in the observance of 20 problems documented as Test Trouble Reports (TTR). Of the identified problems, 3 related to New Generation RVR system operation, 7 related to ASOS performance, and 10 were associated with RVR installation and instruction documentation. Initial analysis indicates problems relating to RVR system operation will have a minimal, if any, impact on New Generation RVR/ASOS Interface performance. OT & E resulted in no problems directly relating to New Generation RVR/ASOS Interface operation. As a result, ACT-320 recommends deployment of the interface after the successful completion and passing of remote maintenance monitoring tests.
