That said, I fail to see what is wrong with Lydd or Southend or Biggin - or indeed Bournemouth where you have just shot some approaches so you know which way round the NDB hold is

and its weather is going to be exactly the same as Southampton's.
Fair enough. You then have 2 choices. Do it your way or do it the way suggested by your school. I'd advise the latter.
...BTW, the wx at Bournemouth is not exactly the same as Southampton, you can have zero-zero fog at Bournemouth and CAVOK at Southampton.
It would be helpful if they were written down somewhere. Otherwise, the appropriate level of immersion will be hard to achieve
Have a look at the IR manual here:
http://www.pplir.org/images/stories/...al%20v1.53.pdf Ulitmately though, we are discussing some very secondary debriefing points (into wind power checks, choice of alternate). Despite all the efforts at standardisation, you are never going to avoid someone who flies with you for the first time as 170A or Test examiner having some such points to debrief on. If that is all he picks you up on, you are laughing, because you will have passed (IMHO).
