UnReliable IAS is a quick-reference tool for the Boeing 777 and 787 "Flight With Unreliable Airspeed" non-normal procedure. Enter aircraft type, weight, and flight level to get the pitch, thrust, and speed targets for each phase of flight: Climb, Cruise, Descent, Holding, Terminal Area, Final Approach, and Go-Around. Supports: - 777-300ER and 777F - 787-9 and 787-10 Also includes the Immediate Action items as a fast, always-available reference on the flight deck. Settings let you choose the fleet shown (777 or 787) and set the maximum takeoff weight for each type; the weight keypad then accepts values only up to that limit. All values are drawn from and computed on the manufacturer's QRH tables (B777 QRH Rev-66, B787 QRH Rev-25). Where the QRH publishes no data, the app shows Out of Envelope. This app is a quick reference only. It is not approved for operational use and is not a substitute for your company's manuals or the manufacturer's QRH.
