• Abstract:
  The Descent Advisor (DA) automation tool has undergone a series of field tests
  
  at the Denver Air Route Traffic Control Center to study the feasibility of
  
  DA-based clearances and procedures. The latest evaluation, conducted in the
  
  fall of 1995, expanded the operational nature of DA testing to include a wider
  
  variety of test conditions. A total of 197 commercial flights from three
  
  airlines participated in the study over twenty-three days of testing. Aircraft
  
  included large and heavy jet transports, both conventional- and
  
  flight-management-system-equipped, and turboprop commuter types. The primary
  
  objective was to measure DA trajectory prediction accuracy for use in
  
  validating DA metering advisories and developing conflict-probe error models.
  
  Previous evaluations, involving large jet types only, demonstrated an arrival
  
  time prediction accuracy within 20 sec. The 1995 test results indicate a mean
  
  error of 0.5 sec late with a standard deviation of 14.3 sec. The least
  
  variation was found for flight-management-system-equipped jets with a standard
  
  deviation of 11.9 sec compared to 15.2 and 15.4 sec for conventional-equipped
  
  jets and turboprop types respectively. This paper describes the test and
  
  presents an analysis of the descent trajectory prediction accuracy in terms of
  
  errors in the horizontal profile, altitude profile, and arrival time. 13p.
