When I use CPDLC for clearance request in the ini A340, I can send the request,I see it in BATC, then see the response in BATC, but it never comes to the flight deck, so there's no way to respond or acknowledge it.  This seems to work fine in the A350.

I had the same Problem and also I was able to see the response in BATC (with SU4 Beta). Thereafter, I flew the Fenix A320, and I got the missing CPDLC Response from the flight with the A340, so the message was definitely created, but not picked up by the A340...

Hi @Donald Douglas/ @MMAACCXX

Apologies for delay in response. For BATC, it only supports Pre-Departure Clearance (PDC) via CPDLC currently.

Key things to ensure for proper function:

  • You are on BATC Experimental Branch (v1.6.75 Experimental or greater). PDC is not available on the Early Access branch at this time.

  • You have set BEYONDATC as the CPDLC Source on the EFB 3RD PARTY SETTINGS Page.

  • You have completed your MCDU INIT-A page with information such as FLT NBR and FROM/TO

After that, you can request PDC following the guide below: 

We and a few other testers have confirmed this working since launch, even up to v1.0.2 recently.

I had already done everything you are suggesting, down to the letter--  multiple times, but would never get the response onto the DCDU.

 

I have not attempted since 1.02, but will try again now.

Nope. Still broken.
