I did a sim eval in a 707 seven years ago, without any time in a 707 sim or any jet time whatsoever (I did spend 12yrs as AMT on almost all types of widebody aircraft except the 707 for what it's worth). I did my prep on my own in a Frasca-142 which is very sensitive and hard to control if you're not used to it and makes the full motion large jet sims seem easy to fly. I was extermely well prepared compared to the others and to my surprise I did so well on the eval which was very similar to CX's profile that the evaluator literally could not contain himself going on about it for a good ten minutes saying it's the best he's seen for his past 6 years of doing interview evals including USAF 707 drivers. But in retrospect that job wasn't nearly worth as much as this one to me, so even I don't plan to skimp out on actual sim time before going for the CX eval, even though I did it before and it worked perfectly well for me and now I have a few thousand hours of jet time. This one is too important.
