Mavic Air 2 – Return To Home Testing
2 I've had a lot of questions about it on the channel, so I thought I'd head outside on a beautiful day like today and show you exactly how it works. Now a few things to keep in mind around the Mavs, the gear 2 and return to home, because it behaves differently than most of the quads you're, probably flying today and it's conditionally based and what I mean by that as the Mavic air behaves differently. Depending on how far away from its original home point, it is I'll, explain those three scenarios in a minute, but before I do return, the home is something that a lot of people ask about return to home as a safety feature built into the quad. That can typically trigger in one of three ways you can trigger it manually. So if you're out flying and you've lost sight of the quad, maybe you don't know exactly where it is and you're getting a little panicked. You can hold the button down on the controller or you can hit the return to home button on the application, and the drone will typically elevate to the height you have set in the application for the return to home height it'll spin, to face the home point. It'Ll fly back to the home point and once it's happy it's over the home point, it'll descend and land almost exactly where it took off, because this squad has precision landing built into it. And I haven't tested that yet but I'm going to test that.
As part of today's clip, but it should land almost exactly where it took off and that's 99 percent of the time which you're gon na see when you hit the return to home key now, the other two scenarios can be triggered by the quad. So, for example, if you're flying and the batteries get to a critical low percentage, like 10 percent, the drones going to say, you know what Rick's not paying attention to me and I'm, not gon na make it home if he fools around any longer out here over This lake I'm gon na take control of the question I'm gon na fly home and land it and just let him know that he should be paying attention to that battery level. So, if you get down to 10 percent, the drone is going to fly home. You'Re gon na see beeping on your controller and return to homes going to get triggered and again, if you're, beyond that, 20 meters away it's going to actually do what I just said: it's gon na elevate to the height you have set and it's gon na fly Home the second scenario with the quad is, if you lose connection between your controller and the quad, the quad at that point is essentially untethered it's flying out there with nobody controlling it in the quad nose. I'M gon na give him 11 seconds, but if he doesn't make the connection I have to assume he's, either fainted or the controllers gone dead or something I better get home.
So the drone at that point is gon na trigger its own internal return to home. As a safety measure, it's gon na fly home and land. So all three of those scenarios are exactly the same. If you're more than 20 meters away, it's gon na elevate to whatever height you've, set as a return to home height spin to face home, come back and land, naturally and again, that's the most most common way that return to home works. The difference with the Mavic air two is that there are two other scenarios based on distance where that behavior changes and it's important to understand those, so if you're within 20 meters away. So, for example, if I fly it out, 15 meters and I hit return to home it's, not going to elevate it's gon na fly home at whatever height it happens, to be flying at currently so that's, normally not a problem. If you have crash Boynton's turned on because, if you're out there beyond this and there's a tree between us it'll see the tree and elevate over the tree to get back here. But you need to know that because that can be a really dangerous situation. So if you're within 20 meters it's just gon na fly back it's, not gon na elevate, if you're within 5 meters that's, where it gets really tricky the drone at that point, isn't gon na elevate and it's not gon na fly back at the height it's.
Currently, at it's just gon na land – and that can be really scary, because, if you're out over a lake and for some reason, return to home gets triggered here's your battery levels get low. The drone is going for a swim, there's. Nothing. You can do to prevent that you can hit the return to home, cancel and try to fly it back, but if you're not paying attention you're gon na put that drone down in the water. So it's really important to understand that it's also important that if you're out in the field, you've got tall grass and the drone at that point decides to descend and land it's gon na end up in some cornfield someplace and you're gon na have to go out There and find it probably some broken propeller it's, not it's, so 5 feet it's gon na land within 20 feet it's, just gon na fly back at the height it's at if you're beyond 20 feet, which is a normal scenario for return to home. It'S gon na elevate to the height you've set spin come back and land where it took off. The other thing that people ask a lot about is what, if you're flying above the height you have set for the return to home and the return of homes triggered it's, not going to descend to the height it's gon na fly back or whatever height. It happens. To be out as long as it's above that return to home height, so what I'm gon na do now is test those three scenarios for you, as well as precision landing so I'll go through those in a second, the first one I'm going to put it out.
Probably five meters and I'm gon na kind of hit the return to home and we'll watch it crash into the grass over here now the grass is really short, so it shouldn't be a problem, then I'm, going to take it out. Less than 20 meters hit return to home and have it fly back and land and then we'll go for the granddaddy of return to home, so I'll send it down field I've set the return to home height at 70. Feet: I'll hit the return to home key it'll elevate, the 70 feet spin to come back, come back and land on the mat and then I'll test the precision landing, because I really want to see if that works as well. So stay tuned, we'll get started with the testing first up is the 5 meter test now what I'm going to do is elevate, the quad to about shoulder height and then I'll, send it forward, maybe 10 feet or so off. The mat because remember I have to keep it within 5 meters for the test actually work and then I'll trigger the return to home. Now. What I expect will happen is the quad should start to slowly descend ever so gently into that beautifully soft grass beneath it and then spin down its rotors and, as it starts at descent, remember there's a lot of protections built into this quad, the Mavic air, is An incredibly smart quad, so crash avoidance, is turned on, which means those bottom sensors, both the optical and digital sensors, are looking for obstructions beneath the quad.
Now that won't be a problem here in the field because it's wide open, but if you were flying out in the forest and you a lot of trees around you and it started descending you'd want to make sure the quad would look beneath it to see a Tree underneath it so it would actually navigate to an area where it could land safely, so it didn't Park your quad 80 feet up in a tree, so that's. The first thing that's gon na happen. Now, if it gets closer to the ground and it doesn't see an obstructions and gets really close to the ground, terrain detection kicks in where it's actually looking at the ground beneath it to make sure it's safe to land. There now again not a problem because it's a wide open field and it's, nice and soft, except for that soccer net over there I'll try to stay away from that. But if I were landing in an area that had like a big pile of sharp rocks – or maybe a I don't – know a corn field someplace, it would detect that as dangerous terrain and it would stop descending and it would turn control back over to the pilot. To allow you to navigate it to a safe area to actually land it, so incredibly, smart, quad, so let's see what happens here. I'M gon na spin up the rotors I've got no warnings and no planes in the area. I'Ll.
Take it up 4 or 5 feet. Pretty good and I'll just take it forward a little bit because again I can't gauge 5 metres that's, probably 10 feet all right. Now I'm gon na hit the return to home let's, see what happens, it's, saying landing so it's coming down slowly descending it's checking the terrain underneath it it's landing perfectly nice and gently and it's spinning down the rotor. So it did exactly what we expected it to do. What'S interesting about that is normally you'll, never see this situation because return to home always happens for me anyway, when I'm really far away and I've not paid attention to the battery levels or some reason I lose connection, or if I get panicked, then it happens and Maybe I've lost sight of it over a tree or something, and I want it to come home it's far enough away where it's gon na elevate and fly back home. This is dangerous again if you're on the shore of a lake or something, and it triggers an automatic return to home and you're, expecting it to show back up on the shore of the lake and you're slowly, watching it descend into the water out there. So, in that case, stop it and return it to home manually, but it's important to understand that, because it is kind of a new thing that a lot of pilots get confused by now stay tuned, then I'll do the 20 meter test next.
Next up is the 20 meter test and here's where things start to get really interesting. So for this test, I'll elevate, the quad to about 25 feet and I'll. Let it sit there for a couple of seconds to record its own point and then I'll send a down field making sure I don't go past, that 20 meter edge and I'll hit the return to home key now. What I expect will happen is the quad will stay exactly where it is from an elevation standpoint, it'll spin, to face the home point race back at a pretty good clip when it gets over the home point. It should spin back to the original orientation it's sitting in right now when it took off facing downfield slowly descend and it should land almost exactly where it took off, because the quad uses precision landing now. A couple of things are happening when it's recording that home point the first one is when it sits there it's marking its GPS location in 3d space. So it knows exactly what coordinates it's sitting at for its home point for GPS. The prom with GPS, though, is it's. Pretty cool but it's not greatly accurate, so it's got a little bit of slop in it, which means it'll, get it roughly back to the home point, but a fall it's using is GPS it's going to come down and it can land quite a bit either side Of that mat, the second thing it does, which really enables a precision landing is the downward facing sensors, take a picture of the area below it on takeoff.
So when it's setting its home point, it not only records a GPS coordination, it's looking down and taking a picture of that home point. So it uses GPS to get it back in the rough area. But once it starts to descending it's constantly making minor adjustments to try to match that picture up to land exactly where it took off so it'll be kind of cool to see how close it comes. So let me send it down field I've got no warnings and no aircraft in the area. I'Ll spin up the rotors now I've got to take it up at least seven meters to give it the best shot of recording the whole point. Perfect there's, not a lot of wind it's, not being bounced around all right, that's, probably good. Let me take it down field a little bit now again. I don't want to take it too far. I got to stay within 20 meters, 60 feet that's, pretty close yeah that's good all right. So let me hit the return to home key go home all right, so it's, spinning back towards the mat. It found the mat and it's coming back at a pretty good clip and it's right over to mat and it's slowing down all right, so it's right over to mat at this point a little bit farther this way. So the GPS got it back to the home point it's, spinning around to face its original orientation and it's way off the mat but it's making adjustments coming down all right, so here's what the precision landing kicks in and man is it making adjustments on the way Down it's coming down right on top of that age.
This is so close. I can't believe this it's perfect. It came down right on top of that H. Now again, the GPS coordination would be mind blowing enough to get it back to its home point, which gives you good assurance that you're not gon na lose your quad. But the fact that it's, looking at a picture when it's coming down matching that picture up with the terrain below it to make those minor adjustments to land right. On top of that, H just blows my mind, because you've got this incredibly smart, robot that's flying around and I'm betting. You at this point, Elon Musk couldn't land, a missile that close there to take off points so anyway, precision landings, working the 20 meter test looks like it's a hundred percent like they claimed it would be now the next one is going to be the really exciting One cuz I'm gon na send it way downfield way up in the air and we're gon na hit the return to home key, and it should elevate to the height that we've set in the application spin to face home come home and land again, almost exactly where It took off so stay tuned for the third test. This last scenario is the Big Kahuna and it's a situation. You'Re gon na find yourself in most often let's pretend for a second you're out flying and you're way out over a lake someplace you're 1500 feet out, and you see an interesting flock of ducks that you start following and you lose track of exactly where your quad Is so you get a little bit panicked and you're thinking? I need that quad to come back and you trigger the return of home now.
What should happen that far out and that high up is the quad should elevate to whatever height you've got set in the application, so it's spin, facing back to where it took off, fly back at a pretty good clip spin back to its original location when it Gets over to landing mat and come down and land almost exactly where it is, and because it's got precision landing, it should almost land right there in the middle of the Aged. So what I'm gon na do is spin. It up send it down, feel about 250 feet. I'Ll, keep it about 40 feet in the air to try to keep it in frame and we'll, see what happens now. I'M, going to use the launch button on the application, launch spin up the rotors and it should launch. I got to hold it sorry. Alright, rotors are spinning up. Whole points been updated, it's pretty happy with that. I don't know what's doing there it's thinking about it. Alright it's got its own point set, looks good. Let me send it downfield and elevate alright, so I'm up to about 30 feet in the air about 150 feet, downfield 200 feet alright 250 feet downfield about 22 feet off the ground. Now I'm gon na hit the return to home key let's, see what happens. Let'S listen, go home, okay, it's, elevating alright 30 feet. 45 feet. 50. Feet 70 feet alright, so it stopped at 70 feet. It'S spun around.
I can tell, from the camera view it's coming back boy is that moving it's it's really really moving all rights coming back at a good clip. Now, when the GPS coordination senses is above the mat, it should stop it or slow it down. Alright, slowing down already about 20 feet out it's, slowly creeping up on the mat and I'm, almost over top of the mat and it's stopped. Okay, it's stopped now let's make an adjustments. This direction, it's not happy yet, and now it is because it's spinning. I can tell it's over at some point, it's spinning back to facing orientation of the way it took off, but it seems like it's off the mat, so it's coming down nice and slow. Hopefully, the precision landings are gon na kick in and that picture took up. The landing mat will help it navigate on top of the mat whoa it's behind a mat by quite a bit and it's, not really making any adjustments on the way down. Wait a minute. It moved a little bit there. Oh come on forward. Get up forward, get this white goodness, where we're all rooting for you, oh it's, moving it's moving! Oh this is so exciting. I want to get in there and push it a little bit. Man is that close, that is so close, there's a pretty good wind blow in this direction, all right, it's off the mat, it's off the mat, but listen there's, a wind blowing it when it's coming down.
I think it's incredible. It was 250 feet, downfield 45 feet in the air and it came back and almost landed on the mat, so it isn't precision landing exactly but I'm going to blame a lot of it on the wind and honestly when it comes down that close I'm gon na Try and land it on my own anyway, but let me try the precision landing a few more times and if it gets better, maybe I'll, let it the clip and put that one in and just say that it landed with precision landing. But for me I love the fact that it gets it back close to the home point and I can land it when it gets there. All I care about is I've lost the chasing those ducks and I needed to get it back because I want to land it safely. Rth brings it back in views. I can actually take it land it and put it down where I need to land it now. That'S pretty much all I had for today, so thanks an awful lot for watching.
