Hi all!
I made some experience with steep approaches in SAW - Istanbul Sabiha Gocen. I think they have about 3.5 degrees there on their ILS.
I actually don't have a special flaring technique regarding steeper angles. The only thing i do is that i break the rate a little faster than normally, means that i pull the stick a bit faster back than normally...and...it works...
Kinda funny when you try to keep the spd with the IAE engines and engine anti ice on by the way
