Hi Whopity.
At the time of my initial UK RTF practical exam, and for a number of years thereafter the only 'Shall' with regards to a request at initial contact was 'Request MATZ penetration'.
Given the aviation regulatory hegemonies' coming, going, coming, "Waiting for Godot" stylee, does 'Normally' now mean 'Advised' or 'Shall'?
IMO, unless there is a specific requirement for phraseology at a particular juncture, then any RTF Examiner who marks down a candidate for an initial call that contains Unit c/s, followed by Flight c/s only is being churlish and pedantic.
Dear thread starter, thanks for taking the trouble to ASK.
