Fokker Services is in the process of certifying a window called Skyview for a Boeing 737 that will be slightly larger than 3 typical porthole windows.
Having a window that is 54.5 in (1385 mm) by 19.5 in (495mm) will be an enticing feature for future owners of the BBJ MAX models and VIP designers will certainly be anxious to incorporate it into their plans.
Fokker originally came up with the idea, which would bring in more natural light as well as more pleasing to the eye. Fokker then consulted with Boeing engineers who gave it the go-ahead and will be doing the testing and validation.
Fokker Services, based in The Netherlands, is cooperating with Boeing Business Jets in trying to complete FAA and EASA certification by the third quarter of 2015. This will be an option for all BBJ MAX models as well as the Boeing 737 Next Generation.
