What's Left turns the A330-900's systems into thirteen interactive cards. Fail a part and the card redraws what still works: which surfaces still move, which buses still have power, which bleeds still feed the packs, which detection loop still watches. FAIL A SYSTEM. SEE WHAT'S LEFT. Every card starts from a normal aircraft. Tap a generator, a hydraulic pump, a computer or a valve and watch the consequences ripple through: the flight control law, the backup that takes over, the alerts the crew would see, the procedure that follows. Ready-made scenarios put a whole failure picture on screen with one tap — both engines out on the RAT, green and yellow lost, an engine fire with agent 2 needed. THIRTEEN CARDS • Air conditioning and pressurization • Auto flight • Electrical • Fire protection • Flight controls • Slats and flaps • Fuel • Hydraulics • Landing gear and brakes • ADIRS • Bleed air • APU • Engines DRAWN LIKE THE REAL THING Surfaces, pumps and buses sit on a to-scale A330-900 planform, coloured by the system that drives them. Tap any part to see what it does. Cards link to each other and carry the same scenario across, so you can follow one failure from the hydraulics into the flight controls and the brakes. MADE BY AN A330 INSTRUCTOR Built by a retired A330/A340 captain and type rating instructor and examiner, for pilots preparing for a type rating, recurrent training or an upgrade, and for anyone who wants to understand how an airliner keeps flying when things fail.
