One possible solution would be by getting the regulators to change the goal posts. The current FTL rules are truly outdated and designed for the B707, DC8 era when aircraft range was limited and the airline commercial environment was not so competitive. Whilst terrain avoidance, collision avoidance, air to ground comms, navigation etc... have developed significantly since those glory days, the FTL rules have stayed much the same.
In addition to this, it seem the regulators whether GCAA, CAA, FAA EASA etc... do not really scrutinise or challenge the operators when they apply for variations to this original scheme to make it fit longer flight times, more time zones etc... The old rules obviously don't fit, so rewrite the whole book instead of adding this patchwork fixes, take into account all this data we have collected, and then make the companies adhere.
If the FTL scheme was a terminal designed for B707/DC8, it would have been torn down years ago to cater for the B777/A380/A340.
