Engine Indication System

START-UP SCREEN

A start-up screen displays Flight, HOBBS, and Tach hours, along with the Fuel Remaining
Button. Flight hours are metered when airborne; if the MFI is not able to assess the air/
ground state, flight hours are metered when the engine RPM exceeds 1,250 RPM, this value is
configurable at the time of installation. HOBBS hours are metered any time engine oil pressure
exceeds 5 psi. Tach hours are metered any time the engine has a positive RPM. Tach hours are
incremented with the current engine RPM in proportion to the aircraft cruise RPM value set
during installation. Flight, HOBBS, and Tach hours can also be viewed in the system menu.
