At first glance, Delta 6 looks like a small, “maintenance-style” update.

It’s not.

This release is a major leap forward—because Flight Deck FMS is now benefiting directly from the groundbreaking technology we’ve been building for the upcoming Flight Deck ONE. We ported key parts of that new foundation into FMS, and the result is… kind of ridiculous (in the best way).

Up to 10× faster UI — and even more on networking

Delta 6 introduces a deep internal upgrade that dramatically improves responsiveness:

• UI performance gains up to 10× in many situations
• Even bigger improvements in network communication, especially under heavy data flow
• Smoother interaction, quicker updates, and a more “instant” feel across the app

Why this matters

Flight Deck FMS lives and dies by two things: speed and stability. When the UI is snappy and the network pipeline is efficient, everything feels more like avionics and less like “an app trying its best.”

Delta 6 is a major step toward that goal—and it’s also a preview of what’s powering Flight Deck ONE behind the scenes.

Available now

Update to Flight Deck FMS Delta 6 and take it for a spin. The difference should be noticeable almost immediately—especially if you’re running complex aircraft setups or longer sessions.

As always: keep feedback coming. Delta 6 is the kind of upgrade that makes the whole suite stronger, and your reports help us squeeze out every last drop of performance.
