the ones neglecting safety, not sticking to procedures, having bad CRM, having rusty flying skills, being infantile and not taking the job seriously have all been older men often with decades in the left seat
(My emphasis).
Really? Some of the worse behaviour, I've seen, especially when dealing with Cabin Crew, has come from some in the RHS and the perps weren't always male..but one thing I have learnt over the decades is never ever generalise, because most pilots I fly with of both genders are darned good.
As far as the point of the OP is concerned, the lady has passed the required checks and course so good luck to her...I'm not so sure about the issue of the combined experience level.
