Hello all, I have a question regarding the Fenix A320 (this may also apply to the FBW A32NX). I hope it has not been already asked, I did a quick search here and didn’t find any relevant post.
I tried to simulate an unreliable speed indication as simulated in this excellent 737NG driver:
Airbus Emergencies: UNRELIABLE SPEED INDICATION
I know he’s using the ToLiss A340 but when I reproduce it with the Fenix A320 I don’t get the BUSS (Back-Up Speed Scale). For the speed indicator I only get a gray tape after switching all ADRs OFF. However I get the GPS altitude :
And the weird thing is that the ECAM tells me : - SPD......FLY THE GREEN as shown here:
which is what should be done with the BUSS replacing the classic speed tape :
(extracted from the PDF linked below).
Moreover it’s stated in this Safety First article that the BUSS will be displayed once all ADRs are switched OFF. Acording 737NG video this behavior is reproducible with the ToLiss A340 but from my experience not with the Fenix or the FBW.
Am I doing something wrong? Or is the BUSS a missing feature compared to the ToLiss product? Or maybe is it an MSFS limitation compared to X-Plane 12?
Thank you for any feedback.
Edit: added a figure showing the BUSS
