When I converted my Oz & FAA ATPLs to the UK variety I did a combined test for both the licence & IR. I was asked "Approach speed flapped & flapless, & Vtoss?" and that was about it.
It was a rather windy & turbulent day and he had doubts about being able to assess me due to the met. conditions so there was some discussion about that. We decided to give it a go and assess as we went. I mustn't have been too bad at it 'cos I passed.
