Read full description

PropDeck is a focused ground-school and recurrent-study companion for pilots flying the Bombardier Dash 8 - both the Q400 and the Dash 8-100 (Q100). Built around the way crews actually learn aircraft systems, PropDeck turns the manuals into something you'll open every day. WHAT'S INSIDE - 22 ATA systems, taught for both aircraft: overview, components, normal operation, abnormals and the numbers that matter. - Original system schematics for every system, hand-drawn in a clean technical style - see how each system is built and how it flows. - Limitations decks: weights, speeds, pressures, temperatures and cold-weather limits, as a reference list and a Q&A drill. - Hundreds of flashcards and exam questions per aircraft, with a spaced-repetition queue so the right card comes back at the right time. - Marked tests: a 20-question graded test with a pass mark and a per-system breakdown, plus a hard-only mode. - Dash 8 family: the -100 / -200 / -300 / -400 lineage and what changed between them. - A daily study plan, streaks and badges to keep recurrent study honest. FREE & PRO PropDeck is free to try with a full system (Electrical) plus sample flashcards and questions. PropDeck Pro unlocks all 22 systems for both aircraft, every flashcard, the full exam bank, the limitations decks, flows and the Q100 vs Q400 compare - as a yearly subscription. FOR TRAINING ONLY PropDeck is a study and tutorial aid. It is not affiliated with, authorized or endorsed by De Havilland Aircraft of Canada or Bombardier, and it is not a substitute for approved company documentation. Always fly the aircraft by your operator's AFM, QRH and SOPs.
