I'm having this problem with the E190 FSS, MSFS 2024, beta version with VNAV. A green message appears constantly and I can't get rid of it. Also, both MDCUs remain off regardless of the time, as if the aircraft hasn't fully powered on. I need help.

Hm. I own Randazzo's B744 for p3dv4.5, and I know this green area on our screen where it says 'the Randazzo Boeing 747-400 systems are started'

or something similar, don't know the exact words right now.

As far as I know, the green area indeed vanishes, and not only VNAV runs up, but everything we need, here in my case all three flight management systems (FMS),

sorry if that doesn' say a word to you, Boeing language: portside, second F/O (middle), and starboard. Upper and lower EICAS, ...

Good that you published a screenshot, I appreciate that. I'm not sure if I with a decent Boeing background since more than a decade am able to answer

semi-pro or Pro Embraer E-190 questions.

But it seems as if your two FMS (left and right) remain dark. At Airbus they call it MCDU, and at Embraer..

Multifunctional Control and Display Unit (MCDU)?

Let me say one thing that sound quite incredible.

Is this your first flight with the msfs 2024 E-190? I only ask because I also own Randazzo's B744 for fsx,

and when I tried to start the systems with his B744 p3dv4.5 (which are two separate purchases), I remember to have had a similar problem...

Have you really tried to adjust the brightness of your two fms displays?!

In Randazzo's B744, almost all (!) displays in the cockpit can be steplessly adjusted, from completely dark to very bright .

So, let's make sure that both fms are running and also, both fms displays are not set to 'completely dark' .

We only have to find the knob to adjust brightness of the both fms displays in your E-190. A rough guess.

Anyone?

PS: Randazzo's B744 comes with a very decent and large handbook. And your Embraer?

And... sorry that I didn't see it earlier, Aerosoft forum member since June 14 2026 .
