Parrebellum your quote below refers,
"
I've yet to come across an airline where captains were selected by the co-pilots on a popularity basis"
True, but I bet you could name airlines where captains have questioned how certain individuals could have got command despite their low EQ's and high ratings on the "@rseholeometer" scale.
I guess their number came up and they were in the system right ?
A seniority list, almost by definition, takes that 'personality' factor out of the equation. It is based purely on when you were hired and ability to meet and maintain a pre-determined standard of competence.
This is exactly the problem, no one takes personality into the equation, and this allows dysfunctional personality types to get command despite their apparent technical competance.
I agree that command is not the result of winning a personality contest amongs the junior aircrew, but it is bad bussiness to promote people into positions of power and authority if there is a risk that they will abuse it and cause strife and dissention amongst their sub-ordinates.
possibly I'm too new age in my thinking ??
