netos’’) are grounded and will not operate. Normally, the engine is operated
on both magnetos (switch in BOTH position) except for magneto checks and
emergency operations. The R and L positions are used for individual mag-
neto checks and for single magneto operation when required. When the
master switch ON, rotating the switch to the spring loaded START position
energizes the starter and activates both magnetos. The switch automatically
returns to the BOTH position when released.
7.6.4 ENGINE MONITORING INSTRUMENTS
The aircraft is equipped with electronic engine instrumentation, which is part
of the MFD.
NOTE: For additional information on instrument limit markings, refer to Sec-
tion 2, Limitations.
A Data Acquisition Unit (Garmin GEA24 EIM), mounted inside the instru-
ment panel, converts analog signals from the COOLANT, EGT, MAP, oil
pressure, oil temperature, fuel pressure, fuel flow, voltage, amperage and
tachometer sensors to digital format, which are then transmitted to the
MFD and/or PFD for display.
12 VDC for Data Acquisition Unit operation is supplied through the EIS cir-
cuit breaker.
The PFD presents manifold pressure and RPM in the upper left area of the
display in horizontal tape format and as text immediately nearby. Other pa-
rameters are continuously displayed in the engine data block located in the
right of the MFD. A dedicated full page indication is also available upon pi-
lot’s selection.
System health, caution, and warning messages are displayed in color coded
advisory boxes on the MFD. In addition, the text of the engine parameters
displayed on the PFD change to the corresponding color of advisory box
during an annunciation event.
NOTE : EGT probes are installed to each exhaust pipe. Refer to Garmin
G3X Pilot’s guide for a more complete description of the MFD, its operating
modes, and additional detailed operating procedures for the Engine Moni-
