Guys thank you so much for your input & answers, I never intended this to be a "is she safe - is she not safe" debate but all inputs regarding safety & what she's like to fly has been most useful.
Thanks also for the book & video links chaps, will certainly source them out.
As a side note what is it like converting from GPS/FMS etc to INS? The only experience I have had with INS was ATPL groundschool some years ago and it filled me with dread, what about flying N.A.Tracks with the INS etc? Or am I showing my niaveity and it really is straight forward?
I look forward to getting started on her
