"so that the RJ100 behind you thats flying at the normal 290kts" I didn't know a RJ100 could!
I realise your talking about upper sector work- but arriving into STN the other night we where told to keep 300kts or greater all the way down- change over to essex radar- back to 220kts and take a tour of essex. Surely it would be better to slow us up earlier and waste less fuel?
