Quick note to ATC, a standard 3 degree slope is (as you know) 9oo ft at 3 Nmls 1200 ft at 4 Nmls and 1500 ft at 5 Nmls. The aircraft should ideally be about 180 kts at Glide Slope intercept so that ensures a Constant Descent Apporach at idle power. Here in Dubai, often there are tailwinds up to 4ooo ft on the approach due to the sea breeze and desert temps, meaning at idle power/thrust the aircraft will only just make the G/S descent without having to add to extra drag (spoilers/speedbrake or extra flap or gear).

Having said all that, when changing from the current STARS of 40+ mls to 18 nmls aplease consider the altitude of the aircraft and the speed and don't just vector onto the ILS when 3ooo Ft above profile at 16 nmls, it makes for a 50/50 can/cant make it for us type scenario. I am not saying this is the norm, I am saying the new STARS can lead to this and I kindly ask you to realise our concerns with such a vector onto finals from 3ooo ft above profile with tail winds and huge track shortening.

Just to say I know it can happen ;-D
