Current NEXRAD Cannot Reliably Enable Safe Flight Around Heavy Weather

Autor: William R. Knecht

Publikováno v: The International Journal of Aviation Psychology. 26:46-61

Objective: We wished to assess whether current-generation in-cockpit looping Next-Generation Radar (NEXRAD) can reliably enable safe flight around severe (“heavy”) convective weather.Background: Numerous studies suggest that estimating the closes

The 'killing zone' revisited: Serial nonlinearities predict general aviation accident rates from pilot total flight hours

Autor: William R. Knecht

Publikováno v: Accident Analysis & Prevention. 60:50-56

Background Is there a “killing zone” ( Craig, 2001 )—a range of pilot flight time over which general aviation (GA) pilots are at greatest risk? More broadly, can we predict accident rates, given a pilot's total flight hours (TFH)? These questio

Current looping NEXRAD is inadequate for hazardous-weather flight

Autor: William R. Knecht

Next-Generation Radar (NEXRAD) is an important decision-support tool for air traffic control (ATC). It is currently being introduced into aircraft cockpits, and will be equally important for remote piloting of unmanned aerial systems (UAS). Unfortuna

Effects of Video Weather Training Products, Web-Based Weather Briefing, and Local versus Non-Local Pilots on GA Pilot Weather Knowledge and Flight Behavior

Autor: Jerry D. Ball, Michael Lenz, William R. Knecht

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 54:60-64

This study explores 1) whether video weather training products significantly affect general aviation (GA) pilot weather knowledge and weather-related flight behavior, 2) use of modern Web-based weather preflight briefing products, and 3) whether loca

Testing a Multidimensional Nonveridical Aircraft Collision Avoidance System

Autor: William R. Knecht

Publikováno v: Human Factors: The Journal of the Human Factors and Ergonomics Society. 50:565-575

Objective: This study explores operators' ability to use a multidimensional, nonveridical control display. Background: Veridical displays represent realistic scenes. State space displays represent nonveridical n-dimensional information based on infor

General Aviation Pilot Takeoff into Adverse Weather: The 'Go/No-Go' Equation

Autor: William R. Knecht, Scott A. Shappell, Howard Harris

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 48:340-344

This exploratory study assessed pilot takeoff behavior into adverse weather. Sixty general aviation pilots were presented with three levels of simulated ground visibility (1, 3, 5 sm), two levels of cloud ceiling (1000′, 2000′), and two levels of

Modeling the Big Sky Theory

Autor: William R. Knecht

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 45:87-91

This work examines the mathematical assumptions underlying the so-called “Big Sky Theory” (BST). Given stated assumptions about airspace geometry, the number of aircraft, and the flight parameters of each, Monte Carlo simulations are used to para

Separation Maintenance in High-Stress free Flight using a Time-to-Contact-Based Cockpit Display of Traffic Information

Autor: Peter A. Hancock, William R. Knecht

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 43:16-20

We evaluated the navigational performance of commercial airline pilots in simulated free flight conditions using two cockpit displays of traffic information (CDTI). One display presented minimal essential navigation information. The other added color
