Table 2:
Meaning of the DOP values.
OAT information is required to calculate the true airspeed from the indicated
airspeed and altitude.
In order to provide accurate measurements, the OAT probe must be installed
on a proper place, where the probe is not exposed to the disturbing sources
of heat:
engine heat and exhaust heat,
direct sunlight,
heated air exited from cabin.
It is 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
(aluminium housing conduction).
Please follow these steps to install the OAT probe:
1. Locate a spot in the aircraft taking into account the considerations from
above and drill a
φ
8 mm hole.
2. Remove the external nut from the probe, but keep the washer, internal
nut and plastic insulation sleeve on the probe.
3. Install the probe into the hole
from the interior
. Guide the cable trough
the aircraft to the Aetos display back side.
4. Apply some thread-lock liquid and thread the external nut to the probe.
The liquid is necessary to avoid losing the cap due to vibrations.
5. Tighten the internal nut so that the probe sits firmly and apply thread-
lock liquid on the nut. Do not over-tight it.
