Kneeboard Cards & Downloads
Print-ready reference cards for your flight bag — built on the same FAA/NWS formulas as the calculators, and branded so a hangar friend can find their way back here.
Every card is half-letter (5.5×8.5″) — print at 100% / actual size and two fit on one letter sheet. They print clean on white to save ink. Free, no sign-up, yours to share.
