Abstract
In recent years, electric airplanes have become a topic of great interest for the aeronautical community. From small unmanned aerial vehicles to manned light sporting aircraft, this emerging segment is quickly gaining space in the aviation market. However, the study of electric aircraft performance is still being established. Since the propulsion system is different from internal combustion engines, performance characteristics and operational issues can differ significantly from that of regular aircraft. These particular aspects must be taken into account when preparing the operation. In this paper, procedures for obtaining estimates of electrical energy consumption for mission and flight planning are presented. These estimates are critical to assess mission feasibility, safety margins, costs, etc. The method is based on approximate, analytical solutions, allowing quick calculations, which is convenient for the task, and can also be employed during the conceptual design phase.
