For composite aircraft, the GTP 59 probe must be installed in Lightning Zone 3 and installed
such that it is electrically isolated. For aircraft model-specific information regarding acceptable
lightning zones for the GTP 59, refer to APPENDIX E. Refer to APPENDIX F for lightning zone details.
Regardless of location, the probe must protrude into the air flow when the aircraft is in flight and be kept
away from direct sources of heat (e.g., engine exhaust, direct sunlight, cabin exhaust, etc.) to provide an
accurate air temperature measurement.
