Yes, any frequency that you see, you can touch to nominate to the standby. There is also a FREQ function
that will provide the most likely frequencies that you’ll need based on your phase of flight. Press FREQ and
press a row to nominate the frequency.
• Airport tab allows selection of either origin frequencies if you are on the ground or within 5 nm
of the origin and it shows the destination frequencies when you are within 40 nm of your
destination or more than 5 nm from the origin.
• Enroute shows the frequencies from the nearest ARTCC, and the nearest FSS as well as
approach and departure control frequencies along your route.

When you touch the standby frequency location the IFD540/440 assumes that you want to type in a
frequency. A numerical keypad is launched for entering numbers. The same rules as the R9 keyboard
apply, which are the leading ‘1’ is optional, ‘.’ is optional, the frequency fills in after a certain timeout (3
seconds), pressing ENTR puts it in the Standby and pressing the swap button puts it in the Active.

There is a USB port on the front bezel of the IFD540/440 that allows a single step uploading of subscription
NavData, Charts and Obstacles. This data is available from Jeppesen JSUMs and there are programs for a
single subscription per airplane. The details of how to get the data from JSUMs to the USB port are
complete and will be supplied with updated JSUM instructions at time of certification. Note that the IFD440
does not display Charts but approaches are a part of the Nav database and will be displayed on the map page
and in the FMS.

Yes, the IFD540/440 can be updated without the need to return it to Avidyne. Periodically, there will be
new features added to the IFD540/440 that you have the option to receive. The process for making this
updates is very quick and will include loading it through the USB port on the front of the bezel. The person
or shop will verify the installation according to a service bulletin, and will update the aircraft log books. The
Avidyne position is that any shop that holds a repair station certificate, an A&P, or an Experimental Aircraft
owner with log book signoff authority can perform the update. They will of course, have to follow the
provided Service Bulletin explicitly and mail/fax/email back in the completed update sheet that is part of the
Service Bulletin but we don't restrict this to just Avidyne dealers.

also logs for the installers and Avidyne tech support to use to resolve any issues that may arise on your unit.
