Reference the comments in post 63 about passing concerns, problems, issues, the true state of play, etc up the command chain - in many (most?)cases they already know.
In the past 15 months I have had a Sqn Ldr, Wg Cdr and Gp Capt all in my direct command chain PVR. People on pprune and e-goat complain that when they leave/PVR nobody asks them why. Has it never occurred to you that on some occassions it is because they already know most of the issues that have made you leave? I have had guys in my section PVR, and I already know without a lengthy interview most of the reasons why - they are the same problems that effect me daily!
What I am about to say now is anectdotal (spelling?), but I have heard of an AOC, 1 and 2*s, Stn Cdrs, Wg Cdr squadron bosses all PVRing, things that were unheard of until recently. Knowledge of this must surely have reached the top.
I believe the 4*s are aware of many of the problems, but that doesn't mean they can solve them. CAS can't fix JPA overnight, nor is he allowed to ditch it!
CAS is no doubt looking to build the RAF into what it needs to be by say 2015, that is part of his job, when we will have Typhoon, A400M, Astor, MRA4, Predator, etc.... But he also needs to be able to adequately man the RAF of 2015, with highly motivated, trained personnel, and from where I sit that part of the plan doesn't look like it is working!
