HIGH TEMPERATURE OPERATIONS

Like all similar units, the AeroNav tends to generate a lot of heat,
especially if equipped with a transmitting radio. There is
extensive internal temperature monitoring on all of the electrical
components, and alerts in the form of CAS messages if the
internal temperature gets too high. Part of the temperature
mitigation design is that the metal bezel is intentionally designed
to radiate heat away from the internal components and out of the
unit. This can have the effect of a bezel that may be warm to the
touch. This is considered normal. Note that the rubber bezel
buttons will not conduct this heat and should not be warm. This
condition will be more noticeable on hot days or during long
ground runs. The AeroNav does not require external or forced
cooling air but is designed to accept cool air intake in those
installations where excessive heat is generated by surrounding
avionics or there is significant blockage of air flow behind the
panel.
