Sadly the HTAWS has to be turned off when you’re in amongst the terrain in the 189. Very good for calling out when you’re away to fly into the granite without meaning it but not very good when you’re intentionally placing yourself there. There is no audio inhibit (yet), so its either inhibit it or have constant audio warning going off.
The 189 also takes a lot of getting used to in the mountains! These guys had not too long before finished on the S92 which handles the hills very well. The 189 is a completely different animal. Add gentle/moderate turbulence and it’s not unusual to see ~20 pitch changes.
