As already mentioned under ground and air risk analysis, it is also necessary to specify the ground risk buffer when defining the flight characteristics. Calculating this can take some time with a manual approach – but wingman can help here too. With wingman you can automatically calculate the required value in 3 different ways. The simplest but in most cases least advantageous method is the 1:1 rule, which uses the sum of maximum flight altitude and contingency area. The ballistic method, which also takes into account the flight speed and the behavior in the event of a crash, usually produces more accurate and better results. Simply select “Calculate automatically” with the ballistic method and follow the instructions. Alternatively, there is also the option of calculating the buffer for a drone with a parachute.
