Bucking Bar is sooo right. Delta was a bit late to the game because they didn't want to get locked down with the iPad. At the industry mtg's, several airlines were peeved that Apple isn't open sourced so a company can't just make up their own app--they have pretty rigorous standards ( and we all know how good the airlines are at writing computer code). The FAA was forced to accept the iPad (or other tablet) because American made a stink about it. Now the pilots want these add on's and guess what? Technically the add-on's make the device a flight instrument. Requirements like 35degree viewing angles, HF studies and SARP's apply and the FAA has egg on their face and the pilots are saying "hey...I'm using it on my private plane". This week, we were talking to Volpe (FAA technical Center) and asking about SMGS and their studies on charting. The iPad is 60-70 degrees off center. Volpe never figured this; they thought the device or chart would be attached to the yoke or put on the slide out tray (Airbus). So...they're trying to figure out if they're against a device being used in SMGS ops. No studies have been accomplished. When asked about the Content Locker and accessing manuals during abnormal ops--no studies. They assumed everything was in HTML and not PDF's. The difference is enormous. PDF's require exact words and then every word will be presented. Type in Datalink, New York and nothing comes up. In HTML, it's more tolerant and smart and comes up like a google search. This is going to be a mess for awhile--but they'll get there (on the pilots backs-of course).
