De Facto..
am still baffled when an fo can recognise a be 1900 from a cessna caravan...
I suspect you meant when he "Can't" recognise the difference between what I assume ar two smallish GA aircraft?? Either way I fail to see ANY relevance whatsoever. I'm fairly hot on very small black silhouettes of Warsaw Pact fighters, ships and tanks (irrelevant) but civvywise can just about get the CX types most of the time, (irrelevant). I'd still let my wife and kids fly anywhere with me though - yours too. Back to hand flying - not that we seem to have mentioned it much.
