Aerosoft and ToLiss have recently issued an update to their A340-600. Included in the update is full support for SayIntentions.AI CPDLC.
That means you can now receive clearances, instructions, and updates directly through the aircraft's datalink systems — just like real-world airline operations. No voice required.
We've put together a step-by-step walkthrough showing how to configure CPDLC, connect it properly, and start using datalink communications in the A346. If you've been wanting a more realistic, airline-style ATC experience, this is it.
What Is CPDLC?
CPDLC stands for Controller-Pilot Data Link Communications. In the real world, it's the text-based system airlines use to communicate with ATC over oceanic and high-altitude airspace where voice congestion is impractical. Instead of reading back a clearance over a noisy HF channel, the controller sends it as a structured message to the cockpit. The pilot reviews it, accepts it with a button press, and the aircraft logs the exchange.
Inside SayIntentions.AI, CPDLC works the same way: clearances, route changes, altitude assignments, and frequency handoffs are delivered straight to your aircraft's datalink display. You handle the entire exchange in the cockpit — no microphone, no speaking required.
The ToLiss A346 Update
The ToLiss A340-600 is one of the most detailed long-haul tubeliners available for X-Plane. With this Aerosoft and ToLiss update, the aircraft now speaks SayIntentions.AI's CPDLC protocol natively — meaning the in-cockpit datalink pages, MCDU prompts, and message handling all behave exactly as they would on a real A346 flight deck connected to a CPDLC service.
Whether you're crossing the Atlantic at FL370 or stepping up over the Pacific, the experience matches real-world long-haul operations far more closely than voice-only ATC ever could.
Why CPDLC Matters for Long-Haul Sim Pilots
Long-haul flying is where voice ATC starts to feel less authentic. Real cockpits go quiet for hours at cruise — communications are short, structured, and almost always datalink-driven. CPDLC restores that quiet:
- Realism — matches how the world's airlines actually communicate at altitude
- Quiet cockpit — no need to break the ambience with voice readbacks every few minutes
- Less workload, more procedure — focus on the FMC, the descent profile, and the approach brief instead of monitoring frequency changes
- Accessible — perfect for pilots without a microphone or in a shared environment where speaking aloud isn't ideal
The Setup Walkthrough
Configuring CPDLC in the ToLiss A346 takes only a few minutes once you know where to look. The walkthrough video covers the full flow:
- Confirm the latest ToLiss A340-600 update is installed
- Enable CPDLC in your SayIntentions.AI Pilot Portal settings
- Configure the ATC datalink page in the MCDU
- Logon to the SayIntentions.AI CPDLC service
- Send and accept your first clearance
