Runway Visual Range (RVR) Automated Surface Observing System (ASOS) Functional Test Report
Abstract
Runway Visual Range (RVR) Automated Surface Observing System (ASOS) functions were evaluated during tests conducted at Memphis International Airport (MEM) from April 14 through 16, 1998. Representatives from the Federal Aviation Administration (FAA) William J. Hughes Technical Center Weather Communication Branch performed the testing. Testing was initiated in response to ASOS software modifications which contained corrections to problems existing on earlier versions. The primary intent of testing was to verify that RVR ASOS functions operated in accordance with requirements and to determine if problems could be expected during operation with the Interim and Final Phase New Generation RVR/ASOS Interface. Five performance issues were encountered during testing. Four issues concerned ASOS performance and one related to operation of the HP Palmtop PC, i.e., Interim RVR/ASOS Interface. Since all of these issues currently have "work-arounds" or established methods to avoid/correct the problem, they are not expected to adversely affect Long-Line RVR service. As a result, ACT-320 recommends use of ASOS software version 2.53 at sites designated for Long-Line RVR reporting with the Interim or Final Phase RVR/ASOS Interface.
