## What is UnReliable IAS?

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 Memory Items and phase procedures as a fast, always-available reference on the flight deck.

All values are cross-checked against the manufacturer's QRH tables.

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.
