When switching from Approach to Tower, I often hear the phrase "Roger Papa Charlie Papa, continue approach". What a load of ole crap and waste of effort and breath that is. Unless flying a helo, there's not much else I can do buddy !! In my opinion the "continue approach"-instruction is just a way of buying time but it makes no sense at all.
Saying "continue approach" contribute to situation awareness of other crews on the frequency. Also, surface wind could be stated at this time to make forthcoming landing clearance shorter. However, when ATCO is short of his breath, "continue approach" is the first thing to omit.
