Is the engine hour log stored in non-volatile memory?

Yes, from EMU-1 firmware v0.041 (and onwards) the Engine Operating hour log is stored in non-volatile memory and restored at the start of every session. Note that in EMU-1 firmware v0.022 (and below) the Engine Operating hour log would reset on a power cycle as it was not stored in non-volatile memory.

In the new firmware version (release date tbc), the engine hours will be configurable, allowing the user to enter the current hours already counted from their engine.
