I can't recall exactly what was the track miles left, i did use my mental calculation 3Xtrack miles, due low speed and also crossed checked the yoyo, both indications were high, yoyo way off, my own calculation aprox 2000ft to kill, as for ATC's part, it didn't crossed my mind at that time about the option u mentioned, because i was too fixated on trying to kill height by my own, its the first time i encountered such a situation, being high and having to slow down and at the same time having to kill height. Many other seniors did told me that the ATC at our home base, does not do a very good job for separation as well in the past, but ive never got a taste of it till the other day. Well, from all the tips and advise and calling up another captain for advise, im starting to learn about how to deal with that situation.
