Specifically, what? Loki....
Re-read my previous thread; I commented that unfortunately I've heard British crews making just as much of a mess in the US of their FAA PHRASEOLOGY radio calls as US crews overseas make of ICAO. It goes both ways, but you never hear the US folks complaining over here about long-winded fluffy read-backs on a frenetic rush-hour frequency. Specifically: one of the most common I hear is, the ATIS says read back only Transp.code and atis letter if you've recieved your clearance (due to volume of calls from non-acars PDC equipped a/c) - promptly followed by an entire British waffle-out of the whole clearance. "Better to be safe..." I hear you say. Not so. Do as the ATIS tells you.
I'm always hearing on pprune complaints about "..twenty-five..." or "three five oh". Well, according to the AIM, that is the standard phraseology over here in the US. So until all Brits use it when flying over here, isn't it a little pompous to suggest that all US crews must use precise ICAO when in UK? And if the message gets across, who cares? This is not the BBC world Service attempting to influence what's left of the Empire on HF....
"Philip and I wish all US crews would use One's English..."
