DJI Flight Sim without Drone

Is it just me or does this seem like a strange restriction?

It's a good thing. The actual FC is processing simulated input. You can somewhat realistically test out various gains settings for example, and how that effects flight handling in high winds.

Nothing that can't be simulated... Without the AC

I get what you're saying... took me a bit to process; was looking for Bill and Steve in the thread. But, it's like an aftermarket tune on any performance vehicle... the ECU only knows what it's told. It doesn't matter who's doing the telling. The software only needs to know the AC's response parameters and it can mimic the AC hardware. Admittedly, I do not know the coding strategies between the AC and remote, but there are some **** good real flight simulators out there that do not need to connect to any actual flight hardware.

This did however get me to thinking (as I was tweaking my gain and exp values)... how long (and who's going to be first) until an auto manufacturer allows a similar level of performance control, where you can dial in steering, gas, brake, suspension, etc. based on curves rather than a button that toggles between comfort | sport | sport+ | track...

I can see several sound reasons for any manufacturer to keep sim locked to actual ECU... Only way to make some PC software to actualy and realisticaly mimics parameters of ECU, is by incorporating actual ECU algorythms and hardware protocols and its internal code in that sim - that would expose many proprietary code details to many code savvy users and open a door to code manipulation - in that way sim would get "developemnt platfrom" functionality... Moreover, in order to keep it actual, in such case you would need to update sim with each new firmware, same as you do with a bird. Naturally, there are fair and educated users with positive intentions, who could help to improve code performance, but there are also other ones who could harm your aircraft and manufacturers reputation. I think about it in a same way as about car engine chip tuning and similar mods, which can gain some performance on the expense of realibilty and legal status (emission, noise etc) and which mods are far beyond technical expertise of user (keep in mind that DJI and many others target customers who would like "idiot proof" product with "automatic everything" )

There are similar options already for many hi-tech cars (such as BMW which I personally tested) but they are not exposed to an end user due to extreme impact to car safety and handling... Each automotive sport tuner has tools to dial in throttle response curve, brake balance, steering power and suspession stiffness in the midle of the race - but these software tools are not legal for everyday use due to traffic safety regulations as they can get average user in real lifethreatening trouble... If you ask technology leaders, such as Google, automotive future wil not get you more tuning options but less, as cars will get "inteligence of their own" in order to make "idiot proof transportation" ;)

Fair enough DrMrdalj, I see the reasoning behind keeping trade secrets, well, secret. Still, software can mimic hardware, but I can understand the pitfalls. I suppose there's also the fact that when you port code from hardware to software, you have to maintain it for both iOS and Android, whereas when that code is embedded in firmware it's only written once. Some efficiencies there.

Regarding aftermarket tunes... I understand what you're saying, though may not go as far as saying it's illegal to chip a car. As for liability, there are many vehicles out there with multiple variants of the same engine... they are just detuned for the cheaper models. That exact same engine performs at a higher level when purchased in the higher end model. So tuning an engine up to an already established performance standard shouldn't prove to be a reliability concern. There is however the condition you mentioned... where someone tunes an engine beyond it's stated performance standards. That does have the potential to impact reliability.

Another thought occurred to me... flight sim on an iPad is pretty rudimentary from an operator standpoint. There's no 'camera' view, only your VLOS to pilot the AC, and on an iPad the AC disappears pretty quickly. Is it necessary to have all the nuances and fully functioning responses of the AC and ECU to provide the same training experience? I suspect much of the ACs performance specs are lost in translation with Sim on an iPad. It may be that I haven't used the Sim to its capability, but I did log about 5 hours with it before I spun my props for the first time.

This is completely another interesting topic. As far as I am informed (and I should be, as automotive ingeneer by education) before any public sales car systems are tested in accordance to legaly imposed procedures, to get certified - for mechanical and electrical safety, noise, pollution, and many other criteria. When ANY mod gets introduced to the car, it is legal obligation of modder and user to get car recertified. Usually it takes officialy licensed certification lab to check license of modder, then to check documentation of materials and parts used in mod, and to measure final performance. As silly as it sounds, such procedure is obligatory in my home country even for tinting driver windows or for tinting stop lights... Due to its impact on noise, pollution, etc. such recertification would be obligatory for engine ECU remaps and other engine mods.

Naturally, if your car can pass yearly technical check without noticing any of mods by responsible technician, then you can "bypass" this procedure and keep using your modded car without being fully legal. This is common practice, but it is not legal and by such practice you risk your insurance coverage as well as other accidental complications... It is not what I like, but that is how it is by the book...

Unless it's VW. :p

VW.... Beat me to it. But we see where it got them.
No, no, didn't you hear..... It was a rogue technician doing this on his own without the knowledge of any of the board.
Now, if you will excuse me I have to sow my sides up because they have split due to me laughing so much.

Maybe the same technician could now get a job at DJI working on firmware!

While technically.... possible, I think that would speak volumes to the quality control and oversight processes in place (not) at Volkswagen, to say nothing of the implications to an ISO certified company that failed that kind of internal oversight and review. Easter eggs find their way into Microsoft software... those seemingly random keystrokes that invoke dialog boxes written at the whim of a coder for humor. Harmless, but they did get through audit. So technically, it's possible. But I think it highly unlikely that someone with the power to say yes/no wasn't aware.
 
All this about why its good to be connected to the drone is all well and good but doesn't answer the question, is there a way to use the flight sim without the drone? We all know it's possible to run all sorts of flight simulators without a 747 connected. There are obvious positives of having an option that doesn't require a connected drone; Mobile flight sim training, first of all it looks fun and mini games like those that are on the pc version are a great way to incentivise practise. It is a hell of a lot more convenient not having to lug the drone around. The more convenience and more incentives the more pilots will use it, the better the experience of the pilots the less accidents happen. I'd happily buy a protective case just for the remote so I could carry it with me to train/play the flight sim. Has loads of possibilities gaming too, the Mavic pro controller is especially geared well for this as its built like a gamepad. It is better quality build than any gamepad I've seen!

I answered that question in my post #2 in 2016!

No.

No.

Really, three years on and still nothing? Real shame, I want to practise flying during my lunch breaks in central London....It wouldn't be responsible to actually fly in central without a permit so that leaves me with 2 super loud beeping devices to bring to the pub. Or a beast of a laptop thats capable of the crazy demands of the flight sim....+ one loud beeping device.
