My lowest end Infiniti has the most rudimentary camera and onscreen guidelines and it works fine. If not on current online aircraft, but certainly on future productions.
I understand the certification process will be more tedious and costly, but if we can avoid what could have been a lot worse Joburg BA snafu, isn't it worth the effort?
The wingtips on these planes are not visible from the flight deck. And if cameras can be installed for the sake of pax entertainment surely there has to be an out on the pretext of safety.
