What's New in AircraftPower S

2.4

September 16, 2025

In response to requests from users, I've added the Lycoming O-540-F and IO-580-B1A engines. I've also made a small change — if one exits the engine selector using the "Cancel" button, the selector will be reset to the current engine.

Very useful for getting correct engine power settings for a wide range of conditions for proper engine break-in.
Also for setting up and checking the horsepower constant for engine monitors.

Excellent app

This app (and its companion app for iPad, called AircraftPower) are fantastic tools that every Lycoming and Continental operator should have in flight. The ability to enter your altitude, barometer setting, and outside air temperature, and then set RPM and manifold pressure for an exact power setting, is invaluable!

Outstanding

The app is easy to use in the air, unlike the factory charts, as well as on the ground for planning. I have used it extensively. Fuel consumption would be a nice feature.
