Hi Wilton,Talla radar pretty much gave you a good answer there.
A couple of additional points. If you are arriving on one of the tweed STARs then the TARTN level restriction is part of that so it shouldn't come as a surprise. Also,even if the Talla sectors(126.3,130.975) are quiet,I will still restrict you to min stack at TARTN. The reasoning behind that is because PH radar may well (and often do) have numerous IFR arrivals from the north or from PF that the Talla sectors do not hold details on. No point me leaving you high and fast because my sector is quiet only for PH to have you as number six and give you loads of extra mileage!
Cheers,rolaaand.
