Those sky gods advocating tuning the ILSs when given a non precision or charted visual approaches clearly do not understand the policies of modern major air operators where big aunty FOQA is sifting through post flight data.
Also it is mandatory in some operators' policies to execute an unnecessary go around if the glide slope GPWS warnings are triggered.
Damn, it is a night landing and you are a dot right of localizer at 999ft AGL..and you didn't go around? Gee, auntie FOQA will get you taken off the roster, get to the safety office to explain. All your very convincing explanations will be met by very sceptical and cynical interruptions, the so called FOQA gatekeeper will let you stew before s/he let it on that you indeed did no wrong. Your week or days is already ruined, your blood pressure up and you probably pissed off more nincompoops inadvertently with your enthusiastic defence of your actions. You know now that more eyes are now watching you, waiting for your next social or technical faux pas.
Small hassle? Yes or no. Go figure.
