I think fam flights are of paramount importance. If our companies cannot let ATCO's see the sim, then let them come on the flight deck. This is all about safety. I'm sure there would be no problem with company id etc and correct arrangements. We should all push to brimg this back. I would, and I'm sure my passengers would be pissed off if we crashed due to lack of controller knowledge of what is going on. Having said all that and knowimg how the management of companies work, they will probably wait until the accident has happened and then come up with the idea that they should have fam flights. But after 20 years experience I know that our more experienced managers (less years than many of us) will disagree. We have a choice, petition through the pilots and controllers association or wait for the accident. Up to you.
