The GTP 59 probe must not be mounted in a fuel tank area (wet or dry). An air scoop or a ducted inlet are
an adequate location for the GTP 59 probe. The probe must be located no closer to the inlet edge than the
width of its narrowest opening.
The probe has no icing protection. Temperature measurements may be incorrect if ice accumulates on the
probe, which in turn may affect Engine Percent Power or other data that depend on the measurement of air
temperature.
It is recommended the GTP 59 probe is installed in Lightning Zone 3, although Zone 2A may be an
acceptable location for certain aircraft.
