I have a question to the experienced pilots with waypoints missions. Suppose I start a way point mission at the top of a mountain 1000ft above sea level (frame reference) Phantom shows 0ft altitude at start of the mission . I instruct the phantom to do the following : Elevate to 150ft at Waypoint 1 to clear any obstacle Descent to waypoint 2 which is 60ft above sea level. Head to waypoint 3 which is at 40ft above sea level Elevate back to 150ft at way point 4 then return home through way point 5. In order for the phantom to travel back to the home location , will it know that it has to keep on climbing back ? Obviously, the same question would be asked from waypoint 1 to 2 . Will it proceed with a nose dive or a vertical decent ? I'm told that the average battery consumption of the phantom vision + on a mission is 15% of battery for every mile travel forward. I would guesstimate vertical climbs to be in the 25% of battery per mile. ..
