If it's a training issue that concerns a flight deck member, then the Deputy Head of Training won't be calling you, I or any other member of the flight deck in for tea and biscuits because (as you quite rightly pointed out), they're not qualified to do so!! I'm sure that duty will be carried out by the Chief Pilot and appropriate Fleet Manager.
Therefore could you pick a fault with this appointment (never seen this appointment published anywhere) that's worth debating please? The rest of the pprune community awaits with eager anticipation!!
Or, would it not be best if you took your problems direct to the Managers who can affect change, rather than cry like a two year old on an anonymous web forum?
