Concept of Volkslogger VL 1. The VL-1.0 has the capability of continuously recording the actual positions and corresponding altitudes during the complete flight. 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. The pilot can read the direction and distance to the turn-point. Additionally, the display shows speed and course over ground. Other display pages give information about the instrument status, GPS-status, remaining memory and time of day. This sensible arrangement leads to the avoidance of incorrect rounding procedures, which often result in the loss of points.
