For many years, pilots have used approach speeds referenced to Vmin speeds which they have assumed were 1g stall speeds. See VminAndStallSpeed.pdf for facts about how the Vmin speeds were not 1g stall speeds, relevant consequences, new regulations to require 1g stall speed determination, and adjustment of the indexing factor for reference approach speeds.
Powered flight has been with us for slightly more than one century and within that span of time fantastic advances in every aspect have occurred. Issues of safety have always been prominent.
With regard to matters of the airworthiness and performance of aircraft, my career has provided me the opportunity to both contribute to the body of knowledge and to participate in many aspects directly relating to safety. In doing so, I have had the privilege of representing pilots in national and international forums.
It is my hope that this website will increase access to this body of work so that aviation can increasingly be practiced from a position of strong foundational understanding.
