One has to admit, that ops crew have improved vastly since the days of the premadonnas who thought they were; and were treated as; Royalty, by some Airlines!
Also I think, largely due to the fact that so many "young chaps" are now being placed in command of aircraft(not that I'm in full support of this) additionally contributes to them, generally being more polite & respectfull.
I tend to get along amicably with most of my customer crews from all corners of the earth, including my host company, However....
the single most unacceptable occurance is:
-failure to greet once greeted
-or failure to acknowledge an obviously qualified person who is patiently waiting for flyer boys to collect their toys & finish off their conversations, in the flight deck, whilst as previously mentioned, the fresh crew are waiting in the galley area!
No points for figuring out that just maybe this aircraft is intended to leave in the next 60 minutes, and has just completed 4 sectors down line!!!
A simple courteous good morning, are you engineering; or how are ya doing, works wonders for most people!
I also do not speak to the back of any captains head, nor do I relay through any FO, for any airline or pilot.
If a premadonna shrugs me off in any way... we dont speak again, until he physically approaches me & apologises, regardless of the state of the aircraft or proximity to departure time. And my report will reflect this lack of professionalism.
There are still a few of the fresh command boys who fail to realise that a lot of engineers were certifying aircraft, long before they reached puberty & respect is in order, where the engineers behaviour displays such.
some of us carry licenses for as much as 10 aircraft types & 10 again different power plants.
Its all about professionalism & consideration! both ways
