Abstract

An electronic variometer is designed and constructed to calculate glider's climb or descend rate. A PIC based micro-controller, absolute and differential pressure sensors and temperature sensor are interfaced to serve this purpose. Quantitative and qualitative outputs of the variometer are passed to the user by means of Liquid crystal display, LCD screen and a speaker respectively. A menu interface routine complete with push buttons facilitates the communication between the user and the instrument. Noise reduction starategies are implemented throughtout the design and construction phase of the instrument. The constructed variometer is able to perform NETTO compensation technique and calculating the air mass climb rate outside the glider. Based on the calculated air mass climb rate, the optimised speed of the flight is also displayed. Finally, the variometer is tested to validate the climb rate reading with the specification.
