If my flight plan takes my drone out of wifi range, am I right that it will still execute the flight plan, even though this won't be visible on my phone screen, visiting each waypoint, assuming it has enough battery power and the GPS signal isn't lost?
 
Good question! I've wondered about that as well. What happins if you disable RTH would Drone complete Flight Plan?

From my limited research, the Anafi will complete whatever autonomous mode it is in even if it loses WiFi. What it does at the end of that autonomous mode may have consequences! I have seen several videos where RTH worked as it was supposed to even after loss of connection, IF the RTH altitude was set high enough to avoid all obstacles!!!!

This is a good reason to set the RTH altitude at least twice as high as any obstacle you think might be an issue in twice or even three times the planned radius.
 
Yes it might be but It's what makes a Drone a Drone. I wonder if I can see over that next ridge...and that defines the Human condition..
 
The Anafi will continue with the flight plan just as if it was connected.
What you have to be aware of is what the final waypoint is and the drones action at that. You want it to come back close ( maybe "close the loop" when setting it up) to where you started (or at least where you can see/get to it safely) and either land or even better, hover a good distance (enough to clear anything around that last waypoint)n off the ground in case the landing area changes!
RTH will initiate if the battery gets low... so make sure that is set to a good altitude in case it does decide to come home
Be mindful of ALL of the altitudes along the route so it will clear whatever there might be when it is flying by itself!
It will re-connect when it gets back in range though so it should regain the video feed, etc as it gets closer to the end/home

Yes, but be aware that if the RTH altitude is set to a lower altitude than the one at the end of the maneuver, the Anafi will actually descend to that altitude during the RTH. Something to think about in an environment full of obstacles.

A thoughtful review of ALL settings in the app before even turning on the Anafi will negate most crashes and fly aways.

I use flight plan and Lichi (on DJI) a lot and they both load the plan in memory . If you have a disconnect it should complete flight just make sure you have real solid GPS on take off .

Absolutely right!

A thorough review of ALL the settings/options SHOULD be a prerequisite to even taking off with any "new to you" drone.
I always recommend just turning on and connecting everything and flip through ALL the pages of settings/options before even taking off the first time...but nobody does that
 
It will continue the flight plan although confusingly it wrongly warns that it will RTH. Design your flightplans carefully as once you're out of range you're committed.

Very True..."Commited" is the right word...lol
And good tip about the RTH warning

Nope, that's not right. If Anafi's height is > than the minimum RTH height that is set in the APP, she will fly home at the height she loses the signal or receives an RTH command from the controller. Anafi vil newer decent under an RTH operation on its flying to home.

Yes, and no. If it has adequate battery levels it will continue on its plan as instructed. If it thinks it hasn't enough power to complete the mission it will engage RTH and go straight back to the home position. If it is out of contact and hasn't got enough power to RTH it will go as far back towards home as it can and it will land.

I have done over a dozen flight plans that have involved loss of signal and this is how it goes:-

The screen goes black with hints of white noise, as it normally does when losing signal. Despite prior explicit notification in red across the bottom of the screen that it will return to home if signal lost it does NOT return to home. The map shows the last point the controller knows the drone to be at.
BUZZZ! The controller buzzes! There is another connection with the drone. It updates a new position. The screen goes black again. At this point I usually start speculating about taking up a different hobby. There may be another brief contact again, depending on the altitude and topography. I once got a brief update at what was the furthest extremity of the flight plan, which was nice, but the signal was lost again for several more minutes. The map will update to show a green drone icon marking the last known position of the drone, it stays in the same place and goes red when there is no live connection.
BUZZZZ! It's back! Well, it's alive! It hasn't crashed yet! It's nearly halfway home! Often it will regain signal at just the point you expect it to, at just the position you planned it would. Unfortunately, this often involves severe time dilation and distortion fields. You need to have a clear idea of what time you need to begin to panic. Never launch a flight plan without verifying just before you hit the play button exactly what the duration is. It will usually take longer. Although you can plan to fly it at 11 metres per second it will never manage to achieve that as a sustainable average. You might think three minutes have passed but only twenty seconds have in reality (in this it can be a bit like sex). I now make a point of calculating a "don't panic until" time before I launch the flight plan. Once I passed that time. It was a valid time to panic. There was a buzz! But by this time I knew the battery would be nearly dead. I was right, I managed to get back video from the drone and I could see I had just enough power to make a safe landing but not to complete the return to home. Fortunately, the drone was over a field not a private garden or road. I managed to land and retrieve the drone a few minutes later.


On another occasion, I had launched an ambitious flight plan and the signal had been lost as I anticipated it would be. A good two minutes before I was ready to begin panicking I heard the Anafi hovering above me. Always have the last point in your flight plan within earshot of the place you will be standing, ideally also right at the RTH location. I thought it was highly unlikely that it had completed the mission. It hadn't, I later discovered watching the video that it did a precautionary RTH on the basis of low battery level at the furthest point from home so only half the mission was complete. But at least it did return safely.

I suggest you never plan a mission in excess of 12 minutes and only attempt a flight over 8 minutes if you have already verified that wind levels are modest. The simplest way to check wind levels is to fly a square at maximum altitude, ten seconds flat out North, ten seconds flat out East, ten seconds South and ten seconds West. This should alert you to whether the maximum speeds you can attain are limited or vary significantly with direction flown. If there is a direction that you can't fly as fast in this will impact your flight and you should consider increasing your safety margins or putting off your plan to another day.

The Anafi (and all drones I have ever flown) only adjust the altitude if they are BELOW the RTH height. Are you sure this is what happens? Can you prove it? I find it hard to believe. My own experience is that when RTH is triggered the drone spins to face the home direction then flies home at the height it is at unless it is below the RTH height specified in which case it spins, rises then returns.

No, I haven't proved it yet. A very good test for the next time I fly: set RTH altitude to lowest, fly up to three times that height a couple hundred yard away and hit RTH.

Me and my big mouth. I will post the results. Your previous post contained a LOT of great information for those who have and those who will.....Remember what Doug Adams said: DON'T PANIC!!!! :eek: Or was that Zaphod Beeblebrox? It's much worse if both of your heads panic at the same time!


EDIT: I tried the above and sure enough the Anafi did NOT descend to the RTH altitude. It stayed at the higher altitude until overhead. My bad.

Hi everyone. There is a way to go over 150 meters. If for example they are with flightplan at 300 meters, i interrupt the execution of the flightplan, Anafi remains at 300 meters or goes down automatically?
