If the Mavic loses controller signal while in atti mode (and therefore doesn't have gps lock) what does it do? Is RTH non functional?
 
It will drift with the wind. It can't return home if it doesn't know where it is... it doesn't know which direction to fly.

However, if the GPS lock is transitory (maybe you were flying deep in a canyon or something), and it locks again, it will initiate a failsafe RTH.

And yes there is an ATTI mode, you just can't manually select it.

Oh come guys. Most of the information here is wrong. The Mavic has an Atti mode which is only accessible if GPS mode fails. If your drone is set to RTH on disconnect, it will instead immediately land on disconnect in Atti mode. Same goes for if it is set to land immediately. If set to hover, it will just drift until the power runs out.
 
If your drone is set to RTH on disconnect
I know you know this, but just clarifying for people reading along...

RTH is always automatically initiated 3 seconds after the remote controller disconnects from the Mavic. There is no setting to engage that behavior. What the Mavic does when RTH is initiated depends on the settings in DJI GO and whether or not the GPS data can be used (exactly as you stated).

There is no atti mode feature based on how the OP asked his question.

Loss of signal commands failsafe. It does not fly away.
 
Brother, the mavic has atti mode. Myself and about 1000 other people have experienced it. I was simply asking what the aircraft will do without gps or controller signal. How can it return via failsafe if it doesn't know where it is?

You mean failsafe, not RTH.

RTH is one of the 3 failsafe options.

You misunderstood OP. They asked what happens if control is lost while the Mavic is in ATTI because it has no valid GPS signal. Post #3 has the correct answer.

Post #3 is not correct. See post #7 for the correct answer to the OP's question.

Now this is exactly right.

As for the other guy I was opposed because of the fly away comment. Point is if the controller signal is lost for whatever reason, it will first enter failsafe.
 
No, I meant RTH.

FYI, Failsafe RTH is one of the three types of RTH.
No, your wording is incorrect and confusing.

RTH = Return To Home.
Failsafe = what happens when control is lost.
What happens when control is lost can be set to either Return To Home, Hover or Land in place.
Saying "RTH is always automatically initiated 3 seconds after the remote controller disconnects from the Mavic" is incorrect. RTH will only be initiated if the failsafe action is set to RTH.

And anyway none of this applies to the scenario the OP asked about in the first place... where the only thing the Mavic can and will do is to descend but while drifting away with the wind. Does nobody actually read the question??

While what I've stated above might be confusing to you, it's 100% accurate.

When the remote controller signal is lost for 3 seconds, RTH is automatically initiated. To be more specific, "Failsafe RTH" is auto initiated.

Saying "RTH is always automatically initiated 3 seconds after the remote controller disconnects from the Mavic" is incorrect. RTH will only be initiated if the failsafe action is set to RTH.
Failsafe RTH is always initiated when the remote controller signal is lost -- regardless of that setting. What happens after RTH is initiated depends on whether or not the Mavic is using the GPS data and whether that setting is set to RTH, hover, or land.

Here's some more information from the Mavic manual:

And anyway none of this applies to the scenario the OP asked about in the first place... where the only thing the Mavic can and will do is to descend but while drifting away with the wind.
This is incorrect too.

The Mavic will either descend and land at its current location or hover in place until the battery reaches the critically low level and land. In either scenario, the Mavic will also drift with the wind (if the wind is blowing) since the GPS data cannot be used to hold its position.

Does nobody actually read the question??
Most of your replies include incorrect information, so it's quite apparent that reading the question is only half the battle here.
 
Some of it is due to DJI's wording in the manual not following industry standards, and being confusing in the first place. I can understand you wanting to follow it, but it's worse than explaining things properly. And even still...

Failsafe RTH is always initiated when the remote controller signal is lost
No, no and no. There is no way you can say this, just read the **** manual...

"If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically activated if the remote controller signal is lost for a specified amount of time (3 seconds)"
This is not "always" in any way.

Then you completely omit the "Aircraft cannot return to the Home Point when the GPS signal is weak or unavailable", which is exactly what OP was asking about.

So basically the OP is correct about thinking that RTH (again, that means Return To Home and nothing else, Hover and Land are not "RTH") can't function when GPS is unavailable, and you come tell him that no it always works which is of course completely wrong.

Failsafe is what always comes in play in case of RC signal loss, but what it does depends on several factors. RTH is only one of those possible actions, and it does depend on compass being valid, GPS signal being valid, and failsafe action being set to RTH.

No, it's very simple. And the answer to

If the Mavic loses controller signal while in atti mode (and therefore doesn't have gps lock) what does it do? Is RTH non functional?

is that the Mavic will indeed not return to home if it loses controller signal while it has no GPS lock. There is absolutely no possible debate on that. Just like RTH means nothing else than "Return To Home".

Agreed. I don't think anyone in this thread is saying the Mavic will be able to return to the home point.
