RYR's first a/c did not have winglets and then were retrofitted as later deliveries came with them as standard.
Curious why the takeoff & landing cross wind limits were different with & without. Was told it was the usual 'demonstrated' figure. Given it was used as a limit I wondered why a demo was necessary for such a small mod. There is no ground clearance issue, and I'd be surprised with there was a roll handling issue. Why not just use the higher value for both variants?
