I saw this posted elsewhere. I don’t understand; why are folks assuming this airplane is the PMDG Max?
It’s not a given but there is the PMDG beta team tag. I don’t think they would use the Brerok Max

You have what appears to be a frozen virtual cockpit. I never experienced this in the PMDG 737 line until release of the tablet. After that, I have experienced it about half a dozen times. All displays in the cockpit are frozen, no switches or controls can be interacted with using the mouse, but the simulator itself continues to run and the tablet can still be used. The tablet is coded in Javascript; the virtual cockpit is C++/WASM. That indicates to me that the WASM code of the aircraft interface is what has frozen since the plane itself continues to fly and can actually be controlled with physical controls like a yoke and throttle.
I had an unrelated issue a couple weeks ago where my tablet wasn’t updating along with the aircraft when updating using the PMDG Ops Center. After a full uninstall (including manually removing “pmdg-73x” folders my Community folder and several others deep inside my %APPDATA% folder, followed by downloading fresh installers and reinstalling, I have not (yet?) experienced a similar virtual cockpit freeze.

I’m quite a few flights in too now with no hangs/freezes after a reinstall. I only uninstalled in windows apps and a downlaod and reinstall from pmdg website and so far no cockpit freezes, so reinstalling would certainly seem to fix this issue.
I was thinking the iFly, but missed that it’s showing MSFS as the game thumbnail. Weird, isn’t it, that it names the game as Volanta but with an MSFS thumbnail?
I think that just means the Volanta app or website is what’s connected to the Discord account, and that he’s connected to Volanta while flying in MSFS.

This week’s micro-update to the 737 line (3.0.87) is available in the PMDG Ops Center.

i did just a complete reinstall of windows due other reasons and will monitor this
Note: i have further a new xbox account for msfs so i am the guy you are replying too
Just returned to the 737 after some time away so I am a bit rusty. I was doing the RNAV-X 31 approach into KLGA and when getting close to the IF I pressed the ITV-SPD button and the speed window opened but the PFD annunciator continued to show “FMC Speed”. I was expecting it to say “MCP Speed”. What am I missing?
I have both the 700 and 800. But I have had to put the 800 back in the hangar. I can’t get the thing to stop bobbing up and down. The 700 flies like a dream. I have searched for a solution to the bobbing in the 800. I see people reporting the issue. But I can not find a solution anywhere. Any ideas on how I can fix it?
This is correct behavior, as Speed Intervention is a sub-mode of VNAV. When you press Speed Intvtn and the speed window opens, you’re still in VNAV and thus the FMC is still controlling speed commands, but the open speed window just gives the pilot a shortcut to tell the FMC what speed you want.
In short, in VNAV with Speed Intervention active, your speed command goes MCP → FMC → FCC (flight control computer, that commands autoflight).
This came up a while back on the PMDG forum and some folks were doubtful it was correct, so I took a pic at work.
You might have to zoom in, but note three things:
- The FMA annunciates VNAV Path as a vertical mode, indicating we’re in VNAV in cruise.
- The MCP speed window is open, indicating we’re in Speed Intervention.
- The FMA annunciates FMC Speed as an autothrottle mode.

Thanks very much for that clarification. Makes sense now.
Just wondering - what’s the perception of flight sims from RL airline pilots? A “game” or something that many of them partake in? If they are simmers, do they fly the heavy jets that they fly in RL or are they more into it for the recreational, GA aspect? I posted some pics of a recent 737 “flight” of mine on a non-simming forum and a RL AA pilot came down on me, saying that that’s the last thing he’d ever want to do since he get’s more than enough of this at work.
Speaking as a non-pilot I can certainly say that I appreciate having the RL pilots engaged and able to answer questions and provide RW perspectives, particularly for the more complex aircraft.

I’m not entirely sure about that. Your photo shows the airplane in the cruise and the flaps are up.
The behavior of SPD INTV is different between Basic VNAV and Common VNAV too. But I think the key here is the flaps.
I haven’t flown in 15 days (annual leave). I’ll check next time if the AT mode changes to MCP SPD when the flaps are not up.
It doesn’t, for the reason I stated: if you’re in VNAV, the FMC is controlling speed. I think you’re talking about the difference between the vertical modes VNAV SPD and VNAV PATH; we’re talking about the autothrottle mode.

I am talking about the autothrottle mode.
If you’re “on approach” with flaps not up and use SPD INTV (during an NPA), the airplane will stay in VNAV PTH but it’ll use FMC SPD. The vertical path will be geometrical (PTH) but the speed will be controlled by the FMC. It does this knowing that the increased drag provided by the flaps will help achieve the speeds without making the descent path more shallow. This is what allows us to fly non precision approaches in VNAV all the way to the runway while still flying standard speeds.
But like I said I’m not entirely sure as I haven’t flown in weeks and I haven’t done an NPA. It could be that it stays in FMC SPD but the speed window opens to follow what you say (MCP->FMC->A/T)

Related question: when do you turn off A/T on your approach? I’ve been practicing some Go Arounds, and in watching a couple of Youtubes that have A/T still on when calling GA and hitting the TOGA button.
I feel like we’re saying the same thing here? “On approach” logic doesn’t change this behavior, so with flaps up or down, the autothrottle mode will always remain in FMC Speed with speed intervention selected.
Most operators turn the autothrottles off when disconnecting the autopilot. There are a few that land with autothrottles engaged, despite the fact that Boeing does not recommend this. You’re going to do whatever your company trains you to do.
