What height does DJI Go4 app measure? What every drone flyer needs to know.
What height does DJI Go4 app measure? What every drone flyer needs to know. DJI make ground breaking consumer drones whose popularity has exploded over the past three years.
New drone pilots have never had it easier to fly these amazing tools thanks to the user-friend DJI Go 4 app.
The DJI Go4 app is the heart of the system, enabling the pilot to control camera controls, autonomous flight programs & receive important flight information.
That information is crucial when a pilot is trying to fly with in the rules and law. Never has this been more important than from the 30th July 2018 when changes to the air navigation order mean all drones over 250 grams need to fly below 400ft.
When 400ft isn’t 400ft.
Knowing how high you are flying is essential information when complying with the drone law. The DJI Go4 app gives pilots vertical speed, distance from take-off point and how high the drone is flying…. or does it?
When you delve into the detail, you’ll find the height recorded on the DJI Go4 app is not how high the craft is flying. The height is in relation to the take-off point.
Not a problem if flying in a flat terrain, but could a major problem if not. Here is why.
The changes to the ANO that come in to force on the 30th July 2018, states that the 400ft is from the surface. If the DJI drone takes off from an elevated position, say the side of a hill that sits at a height of 200ft The DJI UAVclimbs to 400ft then flies out horizontally over the valley with-in visual line of sight.
The DJI uav is telling the remote pilot they are flying at 400ft, so the remote pilot thinks they are complying with the law.
An aircraft flying the valley at 500ft sees DJI uav flying above their position, and reports the occurrence.
The situation is :
- Remote pilot thinks UAV is at 400ft.
- DJI UAV is really at 700ft.
- Aircraft pilot at 500ft.
Whose right, whose wrong?
The remote pilot has no way to comply with 400ft using the current DJI Go4 app. like wise authorities will have a hard time to prove that the remote pilot was higher than 400ft as the primary evidence would be the confiscated drone equipment.
Drone equipment that would be giving the same information as read by the remote pilot.. 400ft. It’s a potential stalemate situation, waiting for a test case to happen.
Commendable as the changes to the UK ANO are, one has to think solving a potential problem, has spawned another?
