How are both Hobbs time and Tach time computed? Is there an RPM threshold for Tach time (if so what is it, and can it be modified)? Does Hobbs time start when the master is turned on, or must the engine be running? And where is Hobbs time displayed on the EFIS?
Thanks

According to pge 39 in the manual, Tacho Time is Hours on engine above 1250 RPM and Hobbs Time is Hours on engine above 0 RPM. Both are displayed on the maintenance check list page (Press the [CHECK] button followed by the [MAINT] button).

Thanks! Can the 1250 threshold be set differently? 1250 is kind of high.

Ooo, you've got me on that one. Sorry.
