Table 20-2 contains a list of items found in the GTP 59 Outside Air Temperature (OAT) Probe kit
(011-00978-00). The GTP 59 probe has an attached pigtail.
20.1.1 Additional Equipment Required
•
Cables - The installer will supply all system cables.
20.2 General Specifications
See
for mounting dimensions.
20.3 Unit Installation
NOTE
The following instructions are general guidance.
NOTE
The GTP 59 is a Resistive Temperature Device (RTD) that detects changing temperature
by monitoring small changes in resistance. For optimum accuracy, take care to avoid
introducing extra resistance, such as loose, dirty, or corroded connections in the wiring
path between the ADAHRS and GTP 59.
Consider the following recommendations when determining the mounting location for the GTP 59:
•
Do not mount the GTP 59 where aircraft exhaust gases will flow over it.
•
Do not mount the GTP 59 where it would be affected by heated air from the engine or exhaust. On
most aircraft this includes any location downstream of the engine compartment.
•
The GTP 59 must be exposed to the outside airflow. Do not mount the GTP 59 in a sheltered
location where it is not exposed to outside airflow (for example, inside a wing or landing gear
bay).
•
For best results, do not mount the GTP 59 where it will be directly heated by the sun when the
aircraft is parked.
