It's mentioned in the annual report:
Regional Express will be installing iPads in all 51 of its Saab 340 fleet in a move designed to improve communication and data access flow while bringing other operational efficiencies to the pilots. The iPads with 3G connectivity will store the full suite of Company Manuals and have the capability to generate performance data for take-off and landing. In addition, the iPads will provide automatic transfer of all engine trend data analysis to engineering. The iPad installation program is planned to commence in September 2012
