happ1ness - might I suggest that the reason why 'the Powers that be' don't give more thought to the practicalities of RTF is because THEY don't have to deliver the goods at the coal face, day in and day out. And to all the pedants out there - just because it's the gospel according to ICAO Doc or MATS Vol x does not mean that it is the best or most suitable practice. Just because 'its in' does not preclude questioning a possibly flawed procedure. Nineteen Seventy Seven - good night!

Correct....

Nothing precludes questioning any procedure, but deliberately contravening one?

I sat on the phraseology working group at SRG that decided this change. No civil ATC rep agreed with it and I suggested that we file a difference with ICAO for class G airspace below FL100, but the RAF rep (probably not a controller) said that they had no objections to full implementation, so that carried the argument. Notice how many military ATC units use the new phraseology? I don't think it's reached JSP 552 yet.

More incorrect readbacks from pilots. Very frustrating on very busy days.... :ugh:

Well said that LCE;)

Well here are the results of a morning using the new procedure....... 28,yes 28 incorrect readbacks on frequencies alone:( :( :( . I rest my case. And yes, I will be filing some sort of report on what I consider an unacceptable procedure and associated increase in workload.

I keep getting frequencies wrong I have been using for the last five years and I only have 3 to remember and none of the pilots read back the extra digit. Every day I seem to have at least one aircraft calling me by mistake wanting another unit. Before this ridiculous rule it only ever happened once a month. Why cant we implement it only when it is necessary :ugh:

Just as a matter of interest, how many 8.33 kHz frequencies are allocated for use in UK airspace?

I think it's just increased from 1 to 3, but under ICAO rules only 1 makes the entire airspace declared an '8.33 environment'. As I said, I suggested we file a difference, after all 8.33 is only going to be used above FL195 initially and is never going to be allocated for use below FL95 in the foreseeable future.
