Iberia (Madrid) will be the first Spanish airline to equip cockpits with the “Electronic Flight Bag”. The new iPads will replace the checklists, manuals, and other paper documents used in flight preparations and operations, and even to perform the calculations needed.
The devices will increase efficiency and safety, while reducing aircraft weight by some 60 kg., for overall savings in fuel worth an estimated 150,000 euros per month for the airline on short and medium haul routes.
According to the airline, “these electronic devices will provide instant access to all aircraft manuals, and to allow pilots to perform calculations of speed and distance during all phases of the flight. This application will enable the flight crews to view navigation maps and detailed airport maps.”
Iberia has already fitted one Airbus A321 (EC-ILP) with iPads for both the captain and the first officer. Iberia will soon equip an additional four short-haul and medium haul aircraft with the devices, which remain connected with the aircraft electrical system at all times.

It is not true. Pan Air Líneas Aéreas is the first Spanish airline has approved the use of the EFB’s in their cockpit by the Spanish authority (AESA) . (http://www.aviaciondigitalglobal.com/noticia.asp?NotId=23321&NotDesignId=4)
Thank you Enrique. I guess Iberia in their announcement did not know about Pan Air’s accomplishment. All the best.
