We consider the problem of a vertical climb that minimises battery power consumption. We obtained equations for the velocities of optimum and quasi-optimum ascent along with an equation for computing aircraft thrust-to-weight ratio that ensures optimum ascent. We studied the effect that varying the electric motor energy conversion efficiency had on optimum ascent computations. We derived an equation for estimating the electric motor energy conversion efficiency in aircraft hover mode. The article presents propeller aerodynamic parameters required for determining the optimum ascent.
