Like others have said, the best advice I could give you (and this is coming from a guy who went a looooong time ago; we were taught how to catch and cook dinosaurs
) is to listen and learn. Really good stuff taught at all three schools. (I also went to acrtic survival as well, also a good course)
From what I remember about survival, they issue everything you bring into the field with you (and will check you aren't bringing anything else). For flyers, it was everything we had in our ejection seat kits and the typical survival vest gear. No need to bring anything else, these kits are well stocked after years of experience and lessons learned from actual survival situations.
Only advice on what to bring besides that is pretty obvious. Bring one of your older field uniforms or flight suits for the field portion, and an older set of boots. They will be TRASHED afterwards.
Oh, and don't make plans to travel (or even go out) the night your course is scheduled to finish if you have the option. You'll be simply too tired to do anything but sleep for a half day afterwards. Trust me.
