the pilot’s eye to the instrument panel. In most aircraft, installing the MVP-50P to the right of the radio stack
would be acceptable. In some aircraft, the visual centerline falls to the right of the Attitude Indicator.

If the powerplant instrument cannot be installed within 8" of the pilot’s visual centerline, AC 23.1311-1B
recommends Master Caution and Warning Lights be installed. Installation of Master Caution and Warning
Lights is covered in this manual.

Installing the MVP-50P may require an instrument (or two) to be moved to a new location. The MVP-50P
replaces eight or more primary instruments in the aircraft instrument panel, therefore moving an instrument to a
new location may not be an issue. If the installer is unwilling or unable to find a location for the MVP-50P, Do

Not Install

Not Install the MVP-50P. The system may be returned for a refund (contact EI for more information).

2.5 Install the Temperature Probes:

Install only the Temperature Probes applicable for your configuration.

A. OIL Temperature Probe Installation:

OIL Temperature Probe Installation:

The MVP system can interface with existing resistive or thermocouple type oil temperature probes or one of
E.I.’s Type-K sealed probes may be installed. See the E.I. pricelist for a list of available probes. Check
that the probe depth does not interfere with the inner workings of the engine.

1/4" -28, Type K. Used on most
engines.

B. OAT Probe Installation:

OAT Probe Installation:

Mount the OAT Probe in an appropriate location on the aircraft, using the hardware supplied. The OAT
Probe is sensitive to air temperature changes. For this reason, do not mount the OAT probe in the path of
the cowl or engine exiting air (i.e., on the belly of the aircraft). Also, if the probe is mounted in the cowling
area, radiant heat may influence the probe temperature. Other than these considerations, the OAT Probe
may be mounted in an air intake vent, on the side of the cowling or anywhere else on the aircraft.

Type K. Used on most engines.

C. Other Temperature Probe Installation:

Other Temperature Probe Installation:

Other temperature probes (Cabin Temp, Cowl Temp for fire detection, etc.) may be installed using current
aircraft standards and practices (refer to AC 43.13). Make sure these probes do not interfere with the
operation of the engine or aircraft.
