The plane points out the various parts of the airplane from engine location to lavatory location in an effort to "educate" air travelers. I really do hope the majority of passengers are already familiar with the location and identity of the engines, but I am not going to mock anyone who doesn't. At least not to their face.
I think it is a fabulous idea and something different to look at next time you are sitting at your gate waiting to board. I will happily board any aircraft painted in this manner; unless I happen to see the Captain and Flight Crew taking notes while doing their pre-flight check.
