Frankly who gives a t*ss if RT phrasology is EXACTLY in accordance with CAP413? So long as its clear, concise, and unambiguous, then who cares.
In my book either:
"G-CD is 10 miles west of Boscombe Down one thousand fife hundred"
or
"10 miles to the west of Boscombe Down, one thousand fife hundred G-CD"
is ok.
What is a load of rubbish though would be:
"We are, er, 10 miles west of, er, Boscombe Down at one thousand five hundred feet, QNH 1013, er, heading 243 degrees, estimate little-piddle-on the-gusset at three five, next is Wells, where we will be climbing to two thousand five hundred and turning southbound."......(which you do often hear....normally in a posh voice)
