TAWS | TERR SYS | GPS Interference

[Michael G.]

Hello dear iniBuilds Team,

With the amount of GPS interference increasing and thus being exposed more frequently to it, I was wondering regarding the TERR SYS.

The GPS interference triggers spurious TAWS warnings (PULL UP). According to the Supplementary Procedures for GNSS Interference, it suggests to consider turning the TERR SYS off:

 

After turning TERR SYS off, the spurious PULL UP warnings should then cease if I understand correctly:

TAD: Terrain Awareness Display

TCF: Terrain Clearance Floor

 

 

What I was wondering, the iniBuilds A350 still continues generating those warnings, even after disabling the TERR SYS via the MFD. Is this correct system behavior?

Any real A350 pilots on here who can shed some light on this? 😇

I'll reach out and ask one of our SMEs on the topic.

Hello. I reached out to the team and it appears that this is indeed incorrect behavior from our A350 in relation to the FCOM, the team is investigating the matter now. Thank you for this report 🙂
