INDICATOR,OAT (P/N 88039) - As Removed

The 88039 is an outside air temperature (OAT) indicator that displays real-time ambient air temperature in the cockpit. This gauge receives input from an external temperature probe and provides readings essential for calculating density altitude, true airspeed, and icing conditions. Mounted as a standalone instrument or integrated with avionics systems, it supports flight planning and performance calculations.

Installation requires positioning the probe away from engine heat and direct sunlight to ensure accurate readings. Commonly found in general aviation and business aircraft cockpits where pilot awareness of atmospheric temperature conditions is critical for safe flight operations.
