VFR Flight Into IMC: Reducing the Hazard

Abstract

Aircraft accidents resulting from initiating or continuing visual flight rules (VFR) flight into instrument meteorological conditions (IMC) continue to be one of the leading causes of fatal aircraft accidents. This paper outlines the nature and scope of this hazard and reviews past and present initiatives designed to reduce it. It also suggests future interventions that may be effective in reducing the threat of this aviation hazard.
