Abstract
The present disclosure relates to flight control of electric aircraft and other aerial vehicles. A computer-implemented method for estimating available range of an aerial vehicle in flight is disclosed, comprising: receiving electrical information of one or more batteries measured using a first sensor; estimating aerial vehicle level energy based on the electrical information of the one or more batteries; receiving one or more of an altitude of the aerial vehicle or a current airspeed of the aerial vehicle measured using a second sensor; estimating steady state force based on the one or more of the altitude of the aerial vehicle or the current airspeed of the aerial vehicle; estimating one or more of a vertical landing range or a horizontal landing range based on one or more of the estimated aerial vehicle level energy or the estimated steady state force; and displaying the one or more of the estimated vertical landing range or the estimated horizontal landing range on a display.
