So I have a P4P+ running current version software execpt for the fly safe file, flew 3 batteries everything is fine. I decieded to download the flysafe file and upgrade it and now this:

Why 394 feet? It's in yellow so it must be a warning. ???? it operated fine for another 2 batteeries even with the message. I did reboot both rc and ac 3-4 times it's still there.

So is it telling you what you've set your height limit at, or telling you the legal limit for that location, or is it enforcing that limit at that location ?

A few test flights should tell.

It is enforcing that limit but I have it set at 122 meters (400.262 ft) anyway so it's not a big deal except that it is uncomfortable flying with warnings I don't understand or why.

Does the FAA not set a 400ft AGL limit, that will likely be why its like that I would think. You'd have to look at flight restrictions to see if it's specific to your location, or is it a new Max' AGL for U.S.A.
In U.K now CAA (Civil Aviation Authority) have now written a 400 ft AGL limit into law, so now an offence to fly above that. For most purposes it shouldn't make much difference I would think.

It is 400 ft but it never came up as a yellow warning message before and it don't live within 5 miles of any airport. It started after I updated the flysafe database.

First I have seen of this.  Glad I didn't update.

Gee thanks............... LOL

Check the Geo Zone Map for your location.

The "Bow Ties" are new as of last week and can extend past 5 miles.......

it's the default setting you can change it.

You can easily check to see what the cause is.
Just change your Max Altitude setting to 50 metres and see what it tells you when you get up that high.

The 400ft AGL rule applies where ever you fly even if the nearest airport is 50 or a 100 miles away (for UK).

Edward J S,  can you uninstall the Fly Safe File ?

DJI updated the fly safe for the USA, so if you live close to certain areas there updates telling how high you can fly, yes FAA says 400AGL but they are changing it. I think the new flysafe is better just getting used too.

Aloha Edward,

     You are getting the warning because you have set your maximum altitude higher than 400 feet.  Reset your max altitude to 120 meters and see if it goes away.  122 meters is over 400 feet by .262 feet.  That makes it a violation and you will get the warning.  Altitude limits are set in meters and 394 feet is 120 meters.

     Just out of curiosity, is the area you are flying relatively flat?  The highest allowed altitude in DJI GO 4 is 500 meters and it has to be set in General Settings.

     I hope to fly tomorrow and I will check to see if the limit has changed.  I recently updated my "FlySafe File" to.  But, the mountains next to my house are supposed to allow me to fly up to 1640 feet.  We will see if it still applies.

     Mahalo for the heads-up!

Aloha and Drone On!

First is to check the FlySafe database and whether a zone has been noted near your location.

Interesting update to see the warnings pop up in yellow now - this must somehow be linked to geo settings.

This is what it is... I didn't know about the changes.

I don't think so...……. won't be updating my other P4P

Aloha Edward,

     It is just your setting.  Reset your altitude to 120 meters and the warning will go away.  I flew today with the new update (updated and restarted today).  No problems.  I could have gone up to 1640 feet (500 meters) in the mountains with my P4 Pro if needed.  And this is right at the 5 mile limit of a military airport.

I wonder if they ever scan the sky, and pick up any of your drones, on the security monitor? Ha

Aloha RHP,

     Yes, they do and if I am in violation, they have in the past slowly taken control away from me.  But that was at least a year ago before the rules were well defined and some of us were accidentally intruding in their airspace.

Fly safe, fly free. Bring it back in one piece. Haha


Yes, they need that security. Let’s Remember Pearl Harbor?

I am not sure I understand your comment. The warning will go away but the OP still will be limited correct, except now limited to 120m. So how is that related to you flying at 1600+ in your location? I ask because I need to shoot around tall buildings. Totally legal to go up to 400 feet above the roof as long as I am within 400 feet laterally of the building. So 500 foot building, I can legally go 900 feet AGL. But I am limited to 393' which makes me worry that auto RTH won't even climb over the buildings if necessary. Any insight that may help here? Thanks in advance.

Exact the reason, I never touch a running system and I never agree to any DJI updates. You'll never know, which new restrictions are implemented without announcement.

Aloha DDG,

     One of the RTH options is to backtrack along the path that got you to the disconnect.  If used, this will return you into a location with communication between the Phantom and the RC without having to go over the tower.  (To me that is the more important question.)

     To answer the other question, 500 meters is the maximum computer limited altitude for DJI quadcopters.  That allows the Phantom to fly up to a maximum of 1640 feet above the device on the remote controller.  

     The RC has no GPS but the Phantom and device do.  If the device does not have GPS, there are certain Intelligent Flight Modes that will not work.  Setting MAX Altitude to 500 meters is how you will be able to get up to 900 feet to inspect your tower and if you went over the top to get to the other side and there you lost your signal, the RTH will still be able to backtrack over the top to get home or at least get the signal again.

     IMHO, Edward's problem was not having input the right numbers.  122 meters is an alert to the DJI software to issue the warning.  It is artificial intelligence after all and takes actions in response to input.  If he sets the max altitude to 120 meters, the message will go away.

     Hope this helps!

Well, I flew downtown last weekend and the ceiling was set for me at 393 or 396 or something. Maybe I never tried to bump it up in the settings because I assumed it was a NFZ safety thing. Another thing that will help is I plan to take off from the roof of the building. That way the roof height is my "zero". I have had active track stop working when the drone goes into negative altitude, and I hope that tripod mode will still function properly even in negative altitude.
Thanks! Oh, and I will check out the different RTH options as well, thanks

Aloha DDG,

     Be very careful when flying around buildings and especially taking off of buildings.  The concrete has rebar and metal will throw off the compass.  When we have a compass problem, one of the first questions we ask is if they took off of a driveway or building.  I do not know how far away the rebar has to be to not interfere but you should do a test at your proposed take-off location to see what the metal interference level is.  You might also be able to do a hand-launch or take off of a wood structure.

     Yes, the MAX Altitude can be set to 500 meters.  That is 1640 feet.  As far as I can tell, Tripod should work at negative altitude.  When I use Tripod, most of the time it is at negative altitude.

     Good luck!

Yes, I pretty much always hand launch and hand catch for that very reason.
