Could someone just confirm a fact for me please, saves me going through hours of posts. What were the different subscale settings? I know the radalts had different settings that the enquiry questioned. Everyone else knew that the settings were similar to threat band settings used by crews in the province. If these are the ones you mean, the rad alts would read EXACTLY the same, one alarming as you enter the threat band, the second when you descended below the band. I quite often operated around the world with different settings.
