I guess it does not matter if there is only two or three aircraft in the TMA. With predominately english as first language pilots. In UK particularly around London, before your reply think long and hard about how many aircraft go through LHR,LGW only one runway 35 millon pax a year, STN, LTN, SOU,LCY it is simply staggering the numbers it really challenges the Eastern seaboard for density. Generally controllers do not have time to ask. Same on initial contact normally into LHR or LGW controller too busy or not enough gaps and they will call you once you fit into their SA. The heavy is a good call I have had a really good shake up into PHL behind a bloody 757 we did not hear a heavy after its call sign so did not know until being shaken what we were following. Its helpful for us sorry it requires more talking really looking forward complete CPDLC operations.
