Enter the engine's max rated power and RPM (e.g. 180 horsepower @ 2750 RPM). For a turbocharged
engine, enter the manifold pressure for max rated power. Max manifold pressure is not entered for a
normally aspirated engine (it's assumed to produce max power at sea level pressure).
Engine power is displayed (in percentage) between the RPM and manifold pressure gauges in the EIS
strip and on the ENG page.
Engine Time – The Engine Time displays the total operating time in hours of the engine. This time is
displayed on both the Engine Configuration Page and the Engine Time Configuration Page. The Engine
Time (Current Hours) can only be changed after unlocking the Engine Time Configuration page by
pressing softkeys 2, 3, and 4 in order, then using the FMS Joystick to highlight the Current Hours field.
The standard value of 2300 RPM is used as a default setting for 1 hour of engine time (i.e. 1 hour of
engine operation at 2300 RPM equals 1 hour of engine time). This value can be changed on the Engine
Time Configuration Page (shown below).
