Fenix Updates A320 to v1.5.2.214

A brand new update for the Fenix A320 has just been released for customers who own the product. To be clear from the start, this is not the ‘Block 2’ update which will feature the new visual modelling, new EFB, and new IAE engine sets. This update, however, is focused on improving some of the flight dynamics, improving various pieces of art and sound, and also fixing an issue with high CPU usage.

In an update post from Aamir on the Fenix Discord server, the new update has rectified the ‘flap 3 drag’ situation, along with polishing the VNAV. There have also been improvements in stability and performance in both the Fenix bootstrapper tool and the Fenix app itself. The full changelog is down below.

This is an update to the already released V2 Block 1, which featured fly-by-wire updates, a new VNAV system and other avionics updates, some new displays, and performance optimizations. V2 Block 2 is still scheduled to release at the end of September.

These updates continue to pave the 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 obtain the update through the Fenix app or by logging into your account and downloading the latest version.

  • Corrected restricting speed constraints below ECON on DES
  • Corrected not restricting speed constraints above ECON on DES
  • Improved ALT* in DES
  • Made LVLCH in DES mode more aggressive
  • Reprioritised below profile and overspeed relationship
  • Fixed occasional inccorect TOD placement over LNAV path
  • Fixed routing after discontinuity+manual leg when inserting SID/STAR/VIAs
  • High altitude speed constraints should appear in mach and be satisfied/ignored as such
