How ?
Replace the in-flight entertainment TVs with iPads !

For this carrier it meant a 7% weight reduction - which is a lot on an airplane.
The things are flight-approved, as chances are the crew already use them to store their route-data, approach charts, as emergency back-up flight instruments and what not.

IPads on a Plane Let Scoot Save Fuel by Shedding TV Tons - Bloomberg

Wow!! 7% weight reduction is huge!

As the comments note, a 777-200 weighs >750,000 lbs, & 7% of that is 52,000 lbs. If the airline flies primarily A-340s, 7% is still 42,700 lbs. The entire aircraft entertainment system only weighs 2 tons, so its removal & replacement with iPads only accounts for a portion of the claimed weight loss.

If they added the winglets to the wing tips, they could lower the drag somewhat. These truncate the vortexes that form there, because of the higher pressure below the wing flowing up and around the wing tip toward the lower pressure air on the upper part of the wing.

Maybe to get the 7% weight savings they removed not only the TV system, but also the seats?
BTW, How much do 400 iPads weigh?

I bet they'll make more money on that than on saving a mere 2 tons of weight:rolleyes:

^THAT is really what is going on. Cash money, and their new way to make it.

...get rid of the passengers and cargo and the plane will fly alot faster and further-per-gallon of jet fuel...but, of course, it won't make any profit either.

The in flight entertainment is more than just those tvs . It is a lot of wiring, power packs, computer systems and routing equipment connectors . I pad is relativly self sufficient.

Can any plane be retrofitted with those winglets?

Some how I don't think the 7% weight reduction is off the total planes weight. Its probably a 7% reduction compared to the existing entertainment system. In the aircraft industry a savings of 100 pounds on an airliner is often worth going after.
