Fenix Simulations Releases A320 V2 Block 1

The long-awaited Fenix A320 update is finally here. Block 1 is now ready to download.

Fenix Simulations Releases A320 V2 Block 1

Fenix Simulations has just released the biggest update for the Fenix A320 since it was first released last year. This all-new version builds on the original with improvements to performance, flight modeling, systems, displays, and much more.

V2 Block 1 contains fly-by-wire updates, a new VNAV system and other avionics updates, some new displays, and performance optimizations. Fenix shared some results from the update that highlights the performance gains users will see.

The changelog, down below, is massive. Aamir even admitted this is a truncated version of a changelog, due to the sheer number of changes being massive (over 1000). Despite the improvements, there are a few known issues in this build. But none of them were seen by the team as worth delaying the overall build to the wider community by a few weeks.

Aamir also added, “whilst all of this is very exciting, there is a very important caveat that should be noted. You are about to go from a mature release that has been proven over 9 months by thousands of users, to a build run earlier today, and tested by a couple dozen testers. Whilst we’ve worked hard to ensure there are no super egregious issues that’ll ruin the fun, we do anticipate a fair few bumps and lumps in this version as we go from an in-house testing team, to the wild west of the entire customer base.”

This is the first ‘block’ of the v2 release for the A320. Block 2 is due to happen at the end of September and will see improvements to the visual modeling, a new version of the EFB, and the long-awaited IAE engines (plus improved engine modeling for the CFM engines). Once we learn more about Block 2, we’ll let you know.

Of course, this is all paving way for future products for Fenix. So far, we know that they plan on releasing the A319 and the A321 by the end of the year as an expansion pack.

You can head to your Fenix account now and download the update. If you don’t already own the Fenix A320, you can buy it for £49.99 from their website.
