Please, why a projector,if that is what it is, in the ceiling when all the seats have screens?
Am I missing something?
Thanks

I think the safety demo still has to played on overhead screens, so if any of the PTVs are u/s the pax still get to see the demo...

That sort of projector hasn't been installed for years. Seats with PTV's that large are only recent. So we can make a pretty good guess that those seats were fitted long after the aircraft was originally built.

It was probably less work to leave the projector in place when the refit the cabin than to remove it.

Thanks, I guess they have similar further back in the main cabin.

It might be that they removed the projector but left the housing. Otherwise they would have needed a new ceiling panel unless they wanted to leave a gaping hole.

Likely that the Projector if not used would be removed to save on the weight.

I doubt it, but you're making a change to the certified aircraft configuration. That means somebody needs to write a service bulletin (time and money) or an engineering order (time and money), get it certified (much more time and money), then do the work. For the few pounds it may weigh, it might not be worth it.

Wonder how much weight would be saved by removing the Projector unit.

I don't know about the specific units in aircraft but those old fashioned "3 cannon" CRT projectors weigh in at somewhere between 25 and 125 kg. Quite a difference compared to a recent LCD projector.

The mount itself probably weighs a bit too if it has to support those kinds of weights up to 4g or whatever.

Cabin furnishings are optional- as such, the aircraft is certified to fly both with and without. They'd have to file that the equipment was removed, but the governing authority in whatever country probably has a field representative that would glance over the paperwork and have this deal done in minutes.

It's still a configuration change. The type is certified with or with furnishings, but for any particular aircraft the built-in furnishings are part of the drawing set. I agree the change is pretty trivial but you can't just yank it out without having certified paperwork to allow it.
