A Proposal for a New Variometer System

Herbert Pirker


The concept of an electronic variometer system has been developed that should be able to measure, in addition to the already known functions of a variometer system, the slope of the glide path (glide ratio) and the cross-country performance during flight. Due to the fact that it is not possible to define a cross-country speed for all flying situations, the cross-country performance will be characterized by the time bonus (or time loss) the pilot gains (or has to spend) per flown distance. By using this quantity for the cross-country performance the pilot is able to find out by trial and error (feedback) optimum flying techniques regardless of the immediate situation (dolphin flying, thermaling, etc. ).
