Flying from EGKR I often listen to Gatwick Traffic just out of curiosity. I often hear 170 knots to 5 DME. However sometimes when i listen i hear 160 knots to 4 DME. At Heathrow, i assume this to be standard practice, as I hear it most of the time.
I was wondering the reasons behind it? Only thing i can think of is RWY selection or Traffic Conditions, amongst a few others i wont reveal to keep my reputation as a pilot intact
