SOFTWARE UPDATES

With very few exceptions, all software inside the IFDs is capable

of being updated via the USB connections as well. This means

the IFD does not need to be returned to the factory for any future

software updates. This updating, however, requires that an

authorized Avidyne Service Center perform the updates because

of FAA conformity requirements. This is not a service that an

individual owner is typically allowed to perform.

HIGH TEMPERATURE OPERATIONS

Like all GPS-NAV-COMs, the IFD tends to generate a lot of heat.

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 IFD 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.

COLD TEMPERATURE OPERATIONS

If the IFD had been exposed to extreme cold temperatures,

responsiveness of the display and to touch or bezel input may

take longer than normal until the IFD has warmed up.
