Simulation of Unmanned Aircraft Vehicle Flight Precision

open access: yesTransportation Research Procedia, 2020
Abstract This paper deals with the Unmanned Aircraft Vehicle (UAV) flight phases dynamics simulation. It predicts the accuracy of the UAV flight using the output graphs. The monitoring of the main flight phases (take-off, en-route, landing) is carried out using instruments, UAV standard procedures and rules established by the applicable aviation ...
