The fuel pressure indicator indicates fuel pressure with the engine pump and/or aux
electric fuel pump in use. This fuel pressure indicator is a mechanical unit.
A standard sealed accumulating hours-meter (Hobbs meter), counts the total time the
ignition key is switched on. An optional air switch may be fitted that accumulates time on
an air switch clock when the aircraft attains a speed greater than 30 knots. The air switch
time can be used for purposes of airframe and engine maintenance.
