Engine Log – This log provides details on fuel flow sensor data
(if configured). It logs at a rate of approximately ¼ Hz;
Event Log – This log contains miscellaneous data such as all
alerts, keystrokes, system status and error messages, etc. It is
designed to be diagnostics log for Avidyne Service Center
technicians and not expected to be used by owners/operators. It
logs at an on-condition rate;
Voltage Log – This log contains internal diagnostic data such as
the voltages and currents on sub-system boards, temperatures
and internal fan status. It logs at a rate of approximately 1Hz.
Download Configuration Info - This log contains the system
configuration for the unit.
The "Download Logs" LSK is presented when "Software" is selected on the SYS tab and the
system is not in-air. When the "Download Logs" LSK is pressed, a pair of Confirm/Cancel
LSKs are presented. Selecting Confirm will launch the Maintenance Mode of the IFD5XX.
From Maintenance Mode, press the right side of the AUX page function key to select the
"Logs" tab. Ensure a USB fob is inserted in the IFD front bezel USB port and then use a
combination of the left side LSKs and the bottom right IFD knob to select the desired
combination of logs and type of action to perform.
Pressing the "Proceed" LSK will immediately start downloading all logs listed in the center
of the page with green check marks adjacent to them. If only a subset of the logs are to be
downloaded, use the "Un-Select All" LSK to deselect all logs and then use the bottom right
IFD knob to highlight the desired log and push in to generated a green check mark.
The "Logs" LSK on that Maintenance Mode page provides two options for downloading this
data via dedicated LSKs. The first option ("Full") allows a download of all data logs onto the
USB fob. The second option ("Since Last") downloads the data logged since the last time a
download was completed. Since the logs contain a large amount of data, the second option
will be a quicker option in almost every case.
Download times are highly dependent on the number and types of logs being downloaded
and how it's been since the last download. Times can range from a few seconds to more than
15 minutes. The more often logs are downloaded, the shorter the download times will be.
