Unfortunately it seems to be the trend for executive managers to reduce themselves to that of politician, who themselves are little more than 20 second sound bites. The idea of a manipulated 50% gender split in recruiting is a wonderfully warm and fuzzy sound bite for the uninitiated purveyor of meaningless media, but in reality it is as plausible as aiming to fly an A320 to the moon.
The simple fact is that the vast majority of qualified Pilot applicants for airlines are Anglo, hetero, alpha males. The reasons for this are many and varied, but that is the simple fact and shouldn't be confused as a form of personal or industry bias or a populist "ism". If an airline wished to bypass even a portion of this demographic then they risk not only being massively understaffed, but also not having enough applicants to even justify holding a recruitment session at all.
Airline recruitment sessions these days are multi-faceted and expensive to run. There is huge pressure within airlines to get the best bang for their buck. Applicants must pass clearly defined benchmarks and any attempt to manipulate the outcome to suit an agenda would ultimately be seen as a waste of resources, possibly open a company to litigation and quietly be shelved as a failed plan.
So when the day comes that executive managers declare that all Pilot recruits will be disabled, post op (non gender specific), left handed lesbians with gender dysmorphia. Then you can rest assured that the fabled "Pilot shortage" has finally arrived.
