THE AWARD-WINNING APP FOR PROFESSIONAL PILOTS Use Before Flight is the essential training app for the professional pilot, helping you prepare quicker and better for your sim check with interactive, immersive training, anywhere and at any time. **SUBSCRIPTION TO USE BEFORE FLIGHT REQUIRED** AVAILABLE FOR A320 & A330 AIRCRAFT ECAM handling and -discipline is key to operating Airbus aircraft. It is crucial, not only in real life, but also at least twice a year when the next simulator check is approaching. All Airbus pilots have experienced this: being in the flight simulator for a check is not the right time to start practicing ECAM handling, quite the contrary. You are expected to know what you are doing, and getting confused can really spoil the day. During line flying and daily operations, however, luckily failures and malfunctions are rare, so proper preparation with just the manuals can be challenging. This is where Use Before Flight steps in. Prepare yourself without the pressure of a simulator detail, wherever you are in your own time. Don’t let those unexpected ECAM lines surprise you! Being prepared will take the stress away and free up capacity you can spend on flying the aircraft and proper decision making. Albeit being the most confusing, it is not just the ECAM handling that matters. Training with literally hundreds of drills, supported by videos, blog posts and documents, will greatly improve not just your system knowledge, but expand your overall abilities as an Airbus pilot! Key features: - Visualise and interact with immersive scenarios with all glass cockpit screens fully simulated - Find content quickly and easily through an intuitive multi-functional menu system - Practice over 250 interactive abnormal and emergency scenarios anywhere and at any time  - all drills embedded for instant offline use - Enhance your training experience further with our unique iconic guidance and by discovering fully cross-referenced related content, such as blogs, videos documents & case studies
