1.2
October 5, 2026
Version 1.2 updates the 787 data to QRH Rev-25 (now up to 270 t) and adds a Settings page. QRH DATA - 777-300ER and 777F: checked against QRH Rev-66 — no changes to the published values. - 787-9 and 787-10: updated to QRH Rev-25. Values were revised in nearly every phase, and a new 270 t weight column was added. The 787-10 Go-Around table is published to 250 t only. - Where the QRH publishes no data, the app shows Out of Envelope instead of a number. SETTINGS (NEW) - Choose the fleet the main page shows (777 or 787) and set the maximum takeoff weight for each type. - The weight keypad accepts weights only up to the limit you set. - Settings opens on first launch and is always one tap away from the gear icon in the header. - The app reopens on the aircraft you used last. MAIN PAGE - Keypad: backspace undoes one key press at a time, and the pad stays up until both fields are complete. - The foot of every Cruise table now has an FL050–FL100 row that points to the Holding page. - Holding and Go-Around messages now say whether the weight has no data (such as the 787-10 Go-Around above 250 t) or only the level lies outside the published band. ABOUT - The header's Caution button has given way to the Settings gear; the caution note now sits at the top of the About page. - The About page also lists the QRH revisions the data comes from. The version line shows them in brackets: 66/25 = 777 Rev-66 / 787 Rev-25. - On iPad, the About page now fills the screen. A quick reference only — not a substitute for the manufacturer's or your company's manuals.
