Airlines of PNG - I think the G stands for Geriatrics. I would say the average age for Captains on the Dash 8 would have to be 60 and counting...
This lot have either come from airline careers (early retirement) or were never good enough to make it to an airline, they preserve themselves on Scotch and live in the past glory days, not facing the fact that maybe they should go to pasture and let some younger guys get the same opportunity they once had when they were starting their careers.
They are blocking the career progress of many young, more capable First Officers with better hearing and eyesight.
Time for the Zimmerframe type rating ......
