2. The discrete input configuration shown in Figure 34-44 will result in a yellow "PITOT TEMP"
alert that will appear on the PFD any time the GAP 26 heater is powered off, or if it is powered on
but the probe temperature is below approximately 25° C (77° F). If pitot heat is powered and the
probe temperature is sufficiently high, the yellow "PITOT TEMP" alert will not appear.

3. The discrete input configuration shown in Figure 34-45 will result in a yellow "PITOT TEMP"
alert that will appear on the PFD similar to Configuration #2, with additional logic that
automatically prevents the yellow "PITOT TEMP" alert from appearing if the outside air
temperature is above approximately 7° C (45° F). This configuration provides the same indication
as Configuration #2, but hides the pitot temperature alert when flying in warmer weather
conditions.
