Concept
The VL-1.0 is a very compact, electronic cross-country flight documentation system, which was developed according to the guidelines and requirements of the International Gliding Commission (IGC). The VL-1.0 has the capability of continuously recording the actual positions and corresponding altitudes during the complete flight. An 12-Channel Garmin GPS-Receiver supplies the required Position Coordinates, an integral pressure transducer measures the ambient air pressure and the Microprocessor converts this value into usable altitude information.
The VL-1.0 enables a complete electronic cross-country flight documentation, which limits the effort required for the evaluation to a minimum. It simultaneously replaces the camera and the barograph. Due to its compact shape the logger is easily mounted on the camera bracket, without further complicating air space observation through
restriction of the field of vision.  Power is supplied by the on-board battery system of the sailplane. With a current consumption of only about 120 mA the instrument does not add excessively to the load on the battery.
