Abstract

Based on two years flight experience with the first battery powered glider, the advantages and limitations of electric drive units as well as the practice of electric flying is discussed. Electric launch systems can offer a single quiet launch plus a reserve for cross-country flying before the battery has to be recharged. Using NiCd batteries, rapid charge allows several starts per day, at moderate costs and a very high reliability. Simple in handling and almost maintenance free, the electric unit is highly comfortable and a very suitable system for gliders. Due to its limited capacity, it does not offer retrieval from extended crosscountry flights.
