Horis User Manual
OAT information is required to calculate true airspeed from indicated
airspeed and altitude, as well as to provide you with the outside
temperature information.
In order to provide accurate measurements, OAT probe must be in-
stalled on a proper place where the probe is not exposed to the dis-
turbing sources of heat:
• engine heat and exhaust heat,
• direct sunlight,
• heated air exited from cabin.
We also do not recommend installing the probe in the heated cabin
area, since the elevated temperature in the cabin may influence the
back side of the probe, though such influence is usually small.
Please follow these steps to install the OAT probe:
1. Locate a spot in the aircraft taking into account the consider-
ations from above and drill a
2. Remove the external nut from the probe but keep the washer,
internal nut and plastic insulation tube on the probe.
