2.3.6 GPS Anten na location
The GPS antenna should be mounted on top of the fuselage in the centerline of the aircraft. Avoid mounting the
antenna near any projections, the propeller, and the T-tail of the aircraft, where shadows could occur. It is
recommended that there be a separation of at least 3 feet between the GPS antenna and any VHF Comm
antenna on the aircraft. The GPS antenna baseplate must be level within ± 5° in both axis when the aircraft is
level (level is defined as the aircraft attitude required when weighing the aircraft for weight and balance). If the
GPS antenna is tilted more than 5° or is mounted close to other objects that shadow it, loss of some of the
satellites will occur and system performance degraded. See manufacturer for specifications of GPS antennas.

Refer to manufacturer’s procedures or applicable STC documentation.
2.3.8 OAT Senso r Location
The OAT sensor should be mounted on the underside (belly) of the aircraft or other convenient location meeting
the following conditions. Avoid mounting the sensor where it can be affected by direct sunlight, or exhaust gases
from engines or heaters. The probe tip should extend beyond the aircraft boundary layer into the turbulent
airflow. See manufacturer for specifications.
