Crisp And Fuzzy Signal Detection Theory And Pilot Weather Judgment: Implications For Vfr Flights Into Imc, Joseph T. Coyne
Crisp And Fuzzy Signal Detection Theory And Pilot Weather Judgment: Implications For Vfr Flights Into Imc, Joseph T. Coyne
Psychology Theses & Dissertations
Weather represents one of the greatest hazards to general aviation (GA), accounting for 15% of the GA accident fatalities. Of the fatal weather accidents 90% are attributed to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) and IMC. An alternative hypothesis is that pilots recognize conditions have deteriorated but are motivated by some other factor, such as pressure from passengers. The present study uses Jensen's Pilot Judgment Model and Signal Detection Theory to explain …
