TBM Boldface is a free training aid for Daher TBM pilots. Study and test Section 3 memory items for your airplane — 700 A/B through 980 — filtered by serial and MOD. Daher does not print the word boldface. They print memory items (grey box in the 900–940 books, bold type in the 960 and 980). We treat those as boldface. Study shows every step on one page so you can chair-fly. Test is write the whole procedure on paper (or recite), then reveal. One card a day, plus Keep going for the rest of the pack. Optional daily reminder at a time you choose. Quick Ref covers Section 2 limits, V-speeds at MTOW/MLW, and engine exceedance thresholds for 700–940. Progress stays on your device and iCloud. No account besides your Apple ID. This is not a substitute for your serial-specific PIM, AFM, or POH. We do not ship the manual. If a step or number does not match your book, trust the book.
