What my manuals? There's nothing like that in the MA manual. OK, found it in the safety guidelines. If it is not a contradiction then this is a mistake because when I first started my MA the DJI GO 4 didn't ask me to calibrate the compass although it hadn't flown for over a month and came from far away.
It’s disclaimer and safety manual, so it has great importance to all users, every user of dji aircraft have to sign this when activating their aircraft so it is prudent to read it.
Although manuals have changed and compass instructions have changed, for instance in P4Pro inspire2 the manual clearly tells you not to calibrate compass until prompted, with Mavic Pro they have changed to calibrate every 10km which would mean that because of battery range of Mavic Pro you could be under the impression that during your flight you might have to land and calibrate, with spark calibrate only when app tells you to, with MavAir we know it has a look up table so it knows where it is in the world so if it needs calibration it will always prompt you, I can vouch for this.
I also have Mavic Pro and have only ever calibrated once as per instructions when I purchased and likewise for P4Pro, I also fly matrice which is a little different but very similar to inspire2 and P4Pro .
Much of the myth surrounding calibration is down to much earlier craft and also incorrect information in older manuals, what dji’s take on the whole thing is somewhat strange my belief is that many crashes caused by bad calibration seen them change from advice to only calibrate when prompted and now we see but only aircraft used by mainly new users a seed change without explanation back to calibrate at intervals. This advice is only for their small aircraft.
Calibration gives the compass the information it needs to determine which magnetic influences are part of the Mavic and what is the earth's normal magnetic field.
The compass doesn't lose calibration and doesn't ever need re-calibration unless you add or remove equipment to/from the Mavic, or aircraft compass has been damaged. |
