FlightDeck EFB – Your ally in the cockpit FlightDeck is the EFB app built for every pilot. It brings the workflows you've traditionally managed on paper into one clean, capable app that works just as well as an electronic kneeboard on an iPhone or iPad mini as it does mounted to the panel or yoke. Get started with these features today, with an exciting roadmap of new features on the way: Digital Checklists Simple yet powerful. Build and customise your own checklists from scratch, or start from one of our free templates. Flights A quick, simple way to log your flight details and reduce your workload in the cockpit. Record times with a single tap and jot down other vital details, making it easy to transfer to your logbook later. Weather Check the METAR and TAF for your chosen airfields at a glance, with decoded conditions or the raw reports, whichever you prefer. Notepad Write down frequencies and clearances with our simple, intuitive notepad. Apple Pencil supported. Documents Keep your own PDFs such as your POH, plates and licences to hand in the cockpit. Your documents stay on your device. Reminders Never miss a date. Track rating expiries, medical renewals and anything else with a deadline, and get notified before it's due. Traffic A traffic display for use with GDL90 receivers, as an aid to help improve your situational awareness. EFIS A EFIS screen giving attitude, ground speed, altitude and traffic data that draws from AHRS enabled GDL90 traffic receivers or simulator connectors.
