keyboard input issue 1.2.1

Featured Replies

After the 1.2.1 update, FMS keyboard input does not work properly. Sim keyboard input works.
 
 

Hi,

When you say the FMS keyboard inputs are not working properly, what do you mean by this, do you have any footage of what isn't working that way we can better understand and assist? When I was in last night I wasn't having issues typing in the 350 MCDU, however other users are reporting issues; so if we can get more recorded instances of this happening, that would help us greatly.

Thank you.

Maybe he means the same issue I mentioned, where the physical keyboard inputs are still being applied to the aircraft when using it to type in the MCDU.

Apparently the event-codes for the KCCU (350 MCDU) have changed? the always perfectly working stream deck profile doesn´t respond for the letter buttons and numerals and FPLAN / PERF / etc. ... did you change these?

I will have to ask the team, thank you for this additional information.

It would seem that is likely.

same thing in msfs2020. I found that i just press CTRL once then type. Press it again to end "keyboard input active"

this is what happens when just pressing the ctrl button and not releasing:

Yes, that's right.

I think you're in a similar situation. I solved it by deleting the keyboard bindings on the MSFS side. It was a hassle though.

I'm taking this opportunity to ask if it is possible to insert this feature in the MCDU 2. It can be usefull during preflight.

No good pilots, only old pilots.

Hello all,

So I have spoken with the developers and it appears that all of our code within the aircraft are still functioning as they are supposed to where both the OIS and MCDU Inhibit code is present, however it seems that something on the simulator side is not being communicated and as such is allowing the OIS/MCDU inputs to also be registered to the sims default/added key binds. We have reached out to Asobo letting them know that this issue is present and affecting the aircraft as such.

Sorry for the inconvenience at this time and thank you for your patience.

Hi, 

This is already a feature since 1.2.1., if you press LCtrl you can control the Left MCDU to type and if you press RCtrl, you can then control the Rightside MCDU and type as such.
