and the statistical evidence for the above claim is... exactly where?
What that it may be?
Well hopefully the AAIB will expand on there statement.
But even if they do I presume you will know better than the AAIB. Just as you know better than the CAA and military when it comes to all things GPS.
And you know better than all instructors in how to teach.
And you know better how to fly than all commercial pilots.
Yes you are correct Backpacker, it is but you need to be quite high to be in that you can quite happily cruise around under I think it is FL295 (My service ceiling is below it anyway at FL250) then you don't need to be RVSM.
