Felix: I think what wiggy is hinting at is that you have 3 questions running on Tech Log. These a simple questions you could and should be asking your in-house instructors. They are simple questions; they should know the answers. They are also items you could ask to see in the simulator. In that way you would have your answers much more quickly and with much more clarity. On Prune, as we have seen over the years, there are quite differing opinions and some down-right wrong answers. Wiggy is suggesting you would be better served in your quest for knowledge by consulting your own training organisation.
