I can confirm that a couple of guys out here that did their stage four in the 73, but mostly all in the King; You will be able to tell which it is by the location of the final stage (Nursling = 737/(320)?, Bournemouth = King Air). Nothing too serious involved, if you get to stage four you'd have to have a pretty bad day not to be joining us out here. Relax; fly like you would in any other lesson and listen to instructions. Good luck.
