I’m not sure what you’re referring to. The real CRJ has no VNAV.

No worries. From the crj thread on the aerosoft forum back in december:
Juicebox, I’m assuming the same as our mod here named Juicebox, replied to the above post by Hans and then Hans quoted and said this:
A quick google search, some discussion in the crj thread on aerosoft, as well as the commentary in the CRJ Pro Answers thread of the Aerosoft forum suggests this is not an accurate statement.

Only, it is. https://bombardieratp.cae.com/fr/node/476
The CRJ’s VNAV is only advisory. IE: it does not have actual VNAV. It indicates what it think is the appropriate attitude, but doesn’t do it for you. That includes the coupled mode. If you think it has a system (real or simulated) that will automatically fly you to a certain level set in the flight plan, be ready to go face first into a mountain.

Excellent, we’ve made progress to agreeing that there is VNAV on the CRJ.
Since you’re more well versed in Aerosoft lore than I am. Do you have any idea why Hans would suggest that there’s a setting to switch between advisory and coupled VNAV when they’re the same thing?
I like the CRJ in real life, and I’d consider buying the Aerosoft one. One question, is it VR ready?

We have not. The VNAV included in the CRJ’s systems is not actual VNAV. The conversation you responded to was about the autopilot having to adjust to maintain vertical speed or flc due to the lack of actual vnav as most people see it.
Because they’re not the same thing. The fact that neither provides autoflight features does not mean they work the same way, exactly like FLC and VS modes don’t work the same way despite the fact that both operate your altitude.
As I understand it, coupled vnav gives you advisory indications based on the levels set in the flight plan on the flight directors. I’m not sure about decoupled, besides the fact that, again, it includes no autoflight.
If you want a better explanation. I’d advise asking TheDude on the aerosoft forums. He’s a CRJ pilot.
Pretty sure we have.
- There is VNAV in the CRJ.
- There is not “Automatic” VNAV (or whatever term we want to associate with VNAV initiating the climb/descent).
- We don’t currently know what exactly Hans means by advisory vs coupled and what changing those does.
This seems like a pretty accurate representation of where we sit, no?
As much as I am excited about this plane I am very concerned about the performance at 3rd party airports.Its probably going to be heavier than FBW
You’re talking semantics. VNAV as most people define it includes autoflight, which is why most will tell you the CRJ has no VNAV. In relation to the topic we were discussing, there’s no VNAV. It’s simple as that.
I’m not interested in further discussing semantics, so feel free to go ahead on your own.
Unlikely. Considering that it’s worked on by a single coder as opposed to a group project, it’s probably better optimized.

It is better if you ask Mathijs or Hans on their forum directly.

Indeed. It’s not like they’re unresponsive.
I know. Abriael is just very well versed in aerosoft stuff so I figured since we were already talking I would see if he knew.
Hans will certainly be the person to ask as I’ve since come across some more posts of his in the p3d crj section that would suggest there may be more to the story.
I know the news related to Aerosoft (and most other third-party devs), pretty much because handling news is my job so i apply it to my hobbies as well, but I’m not a pilot, I’m only halfway through the manuals they’ve made available.
https://forum.aerosoft.com/index.php?/forum/1067-manual-translations/
“Fixed throttle detents for the take-off and climb help setting the correct thrust for these conditions of flight. On the other hand, the CRJs do not have an auto-throttle system and therefore the pilot flying needs to manage thrust in cruise and descent. It also has only advisory vertical navigation (VNAV) capability and therefore decent planning is in the pilot’s hand and experience.”
I am surprised they don’t have a representative here on MSFS forum considering how popular CRJ is. They could help answer many of the questions here just like other third party devs.
I’m not really sure that would necessarily result in the solution. There’s already conflicting information on the aerosoft forum. I think some of it will just fall into the “We’ll know for sure when we have it on the 16th” category.
Status update (not semantics): The p3d CRJ Pro has a autopilot coupled VNAV in the sense that it will descend automatically and it uses the same switch and description to enable in the EFB as we know will be in the MSFS version.
The plot thickens
Just take my cash…
Almost all CRJs have “advisory” VNAV which will give you a visual cue (similar to a glideslope) to indicate whether you are on, above or below the correct descent path. (This is only used for descents, not climbs). The descent profile is calculated based on altitude constraints contained in procedure files such as STARS. With advisory VNAV the pilot is 100 percent responsible for initiating and controlling the descent path - typically using Vertical Speed mode, combined with setting upcoming constraints using the altitude selector. The autopilot will not perform any part of the descent automatically.
Some later model CRJs (mainly CRJ-900s) do have an option for an actual coupled VNAV, where the autopilot will initiate descent automatically, and will level off to meet constraints, but it is by no means as full-featured as the VNAV found in Boeings or Airbuses, or even the Proline 21 VNAV in the CJ4.
The coupled VNAV option does exist in the current P3D version of the Aerosoft CRJ, so it will probably be available in the MSFS version too, but I don’t know if it will be included in this initial version, or added later when they release the 900/1000 expansion.
I’m pretty sure the upcoming release will at least have advisory VNAV, as that is standard on almost all r/w CRJs - even the older CRJ-200.

These are the “NextGen” ones, right?
The man with the answers! Thank you Halber!
On the Aerosoft forum, Mathijs Kok said that the CRJ (like the current P3D version), will have its own stand-alone emulation of the Collins FMS-4200, which will come with a current Lufthansa NAV database, so I assume it does not use any part of the default MSFS nav data for waypoints, approaches, SIDs STARs etc.
