UK controllers should never tell you to maintain a heading
It's a fair cop, guv...
Non standard phraseolgy (by mixing two differing types of instrucion) which will always cause ambiuguity and confusion.
Yes. Case 6 was almost exactly what Man Flex started the thread with.
I think I'll serve this one to an SRG inspector and see if we can have it sorted once and for all
.
One of the things that troubles me slightly is that there is no document that describes in sufficient detail how instructions and clearances should be interpreted. Hence the other favourite thread about level instructions when on a SID.... There's very limited guidance in PANS-ATM and PANS-OPS on any of these issues. I'd like to see that addressed, so that, once sorted this can be carved in a tablet of stone rather than being "PPrune received wisdom".
It puzzles me that some crews believe being told to 'report your heading' is equivalent to being told to fly/continue/maintain your heading'.
So:
7 "Report heading"
Still probably
own navigation because it's in the "Identification" section in MATS Pt 1?
8 "Continue present heading and report that heading."
Maintain a heading mode because it's in the "Vectoring" section in MATS Pt 1.
Trouble is, pilots don't read MATS Pt1...
