I think the issue with the attitude indicator (AI), or artificial horizon gauge, is that the programmers that wrote the subroutines for the display are "gamers" and only have experience with flying drones and have never piloted a real aircraft. Therefore, they have no reference to real world situations and circumstances…
Straight line is wing not horizon in the app.
My complaint is that it is simultaneously displaying two entirely different things. It corresponds to the aircraft's wings moving in the roll axis, but then it's showing the horizon moving in the pitch axis. It would be far less confusing if it consistently showed the motion of only one or the other, not a confusing hybrid of both.It was my understanding that the line is there to indicate the angle of the aircraft's body/wings and not the horizon.
I believe they are referring to the whole display as the "Attitude Indicator." It would be more accurate for them to have titled this section "14. Attitude and heading reference system."Actually, they do call it an Attitude Indicator, right there in the title. The same text and illustrations appear n the manual for the Mavic 3 and Mini 3 Pro.
"Aircraft tilt angle" refers only to the roll axis. "Attitude" includes roll and pitch. The display includes both.
I don't care for the version in the 1.6.8 version of the fly app. Eliminating the white bars that represent the wings was a mistake.
The DJI attitude indicator assumes that the horizon is always in the same orientation - level in the display, parallel to the bottom and top edges of the screen. That probably makes sense for quad drones that don't tilt as much as real airplanes.
I sympathize and agree with @Zbip57. The DJI version of the attitude indicator takes some adjustment if you're a conventional pilot. With the "wings" in the display it was less bothersome. This new version will take some more getting used to.
Sure, black sky over blue water. But that still doesn't solve the problem.Just use black as the sky. Problem solved
I agree especially with Mobile Homer that the indicators in a single instrument are coming from two entirely different "absolutes" with one being the environment and the other the aircraft. So which one is it? The aircraft and how control inputs changed its relationship to the environment, or, is it the environment in relation to the aircraft? I would like the option to make it consistent with classic air instrumentation.It has always shown pitch relative to the horizon, but roll relative to the aircraft's wings. That's what's so confusing.
DJI's attitude indicator uses the old Soviet-style horizon indicator, not the more universally accepted Western-style.Anyone know how full-scale drones or commercial instrumentation is set up?
Hope DJI is reading them.
On the other hand, we're flying remote controlled drones. We're safely standing or sitting on the ground. We are not being subjected to any other external g forces, so our head always knows which way is up, and we know where the horizon is located at all times, and we know it ain't moving. So maybe it is more useful to have a display leaving the horizon level and instead showing how far the aircraft's "wings" are rolled to the right or the left. But if that's the case, then why is the instrument showing the aircraft's "wings" going up when the plane's nose is pitched down in forward flight?
I can see arguments for having it either way.
As a pilot, I'm used to sitting in the cockpit and having my body move with the plane. As the cockpit rolls left or right, I always know (hope!) my wings are still attached in the same place outside my left or right window. The wings never move relative to where I'm sitting. I'm much more concerned about knowing where the horizon has gone. As long as you have a constant 1g acceleration holding you in your seat, your brain will convince you that you're still flying straight and level. You could be in a descending spiral and never even know it or feel it, unless you can see the actual horizon or trust your instruments. If you've grown up using flight sims on your computer, you'll know exactly how an artificial horizon works.

But if that's the case, then why is the instrument showing the aircraft's "wings" going up when the plane's nose is pitched down in forward flight? That's because, in the pitch axis, instead of showing the wings moving, the instrument is instead showing the horizon moving. The horizon goes up as the nose goes down.
That's what's hurting my head.
When I look at that I see the "horizon" moving the the right way in the pitch axis, but the wrong way in the roll axis. Or I see the "wings" moving the right way in the roll axis, but the wrong way in the pitch axis. It just doesn't click intuitively for me that the instrument is supposed to be showing "wings" in roll, but "horizon" in pitch. My head is just not wired that way.
But all they've done is to adopt the Russian/Soviet style of instrument which shows it exactly this way (horizon fixed in roll but moving in pitch). It would certainly have been more logical, and more consistent, to keep the horizon fixed in both pitch and roll.Adopt one convention or another, but don't mix both.
I don't have an issue with that one.Now, for more airplane/drone confusion, let's talk about labelling the fore & aft movement of the left stick the "throttle." It has absolutely nothing to do with aircraft speed.

The weather is good, so I don't want to spend too much time at a keyboard."Throttle" controls engine speed on aircraft, and motor speeds on drones. Neither actually are directly used to adjust aircraft/drone airspeed.
Yes, I have a little time in both power planes and gliders.Yes, of course, a fixed wing aircraft requires engine speed to maintain forward airspeed, as does a drone to maintain hover. But once at any set cruising speed, fixed wing airspeed is more immediately controlled by the elevator and aircraft pitch angle. Pitch the nose up, the aircraft slows. Pitch nose down, it speeds up. That works the same for any fixed wing aircraft, even if it has no engine at all like a glider.
Yes, via a change in the speed/power of the engine caused by adjusting the throttle.Increasing throttle allows the plane to climb without slowing. Decreasing throttle allows the plane to descend without excessive speed. Throttle is therefore used to adjust rate of climb.
It's the same with drones. Pitch angle changes the airspeed, with the flight controller automatically adjusting motor speed to maintain constant altitude. Throttle is used to increase/decrease altitude.
It's a straight copy the Russian style instrument, The fact that the horizon moves in pitch like western style instruments is just a coincidence.I'm speaking from the point of view of a westerner, not a Russian. They kept one aspect, pitch, of the western style and adopted one aspect, roll, from the Russian style.
