7.18.9 Engine and Airframe Timers
The Timers can be accessed from the Engine Menu.
Timer Label Timer Function
FLIGHT Flight timer increments in tenths of an hour whenever
the aircraft is in an airborne state. This can be
triggered via a weight on wheels switch, GPS ground
speed, airspeed, or engine RPM depending on the
aircraft installation.
HOBBS Similar to an analog HOBBS meter that increments in
tenths of an hour whenever one engine is registering
>5 PSI of engine oil pressure
TACH Similar to analog tachometers such that the timer
increments in tenths of an hour based on the current
engine RPM compared to the cruise power setting for
that engine as determined by the installer.
On multi-engine aircraft, the TACH hour meter for each engine will start
incrementing when the respective engine is running, and those TACH timers are
tracked separately from one another. The HOBBS hour meter will start
incrementing when either engine is running, and the HOBBS timer is
synchronized for both engines.
