So glad I gave up the day job..... sorry
Yogibaboo, you have stated in another post that the shortest runway you have landed a CJ1 on was 2953 feet, obviously this was acceptable as per the AFM, but to me it sounds as if you are using the availability of the thrust reversers to provide your fudge factor. But what happens if your air/ground sensor fail and you cant use the thrust reversers?
