Appendix A: Instructions for Continued Airworthiness
INTRODUCTION
This section gives the installer or mechanic information pertaining to maintenance of the EFIS-
D60. Additionally, it provides the steps necessary to ensure continued airworthiness for the unit.
CAUTION
With the exception of replacing the Internal Backup Battery, the EFIS-D60 contains no user-
serviceable parts. Refer all servicing to Dynon Avionics.
INSTRUCTIONS FOR CONTINUED AIRWORTHINESS
Other than for regulatory periodic checks and an annual Internal Backup Battery capacity test (if
optional Internal Backup Battery is installed), maintenance of the EFIS-D60 is “on-condition”
only. With the exception of the Internal Backup Battery, periodic maintenance of the EFIS-D60
is not required.
ALTIMETER CHECK
The following test can be performed on an as-needed basis. If the altimeter is found to be out of
specification, the following single-point adjustment can be performed by navigating the menus to
SETUP > ALTADJ. In the Altimeter Adjustment menu, you can change the displayed altitude by
up to 500 feet up or down. After making this adjustment, ensure that the altimeter on the EFIS-
D60 meets the tolerances allowed between 0 and 30,000 feet. If this adjustment does not bring
the altimeter on the EFIS-D60 to within specification at all attitudes, please contact Dynon
Avionics to return for service.
INTERNAL BACKUP BATTERY CHECK
If your EFIS-D60 has a rechargeable Internal Backup Battery, it is necessary to ensure that the
battery capacity is such that it will last at least 2 hours on a full charge. At least once per year,
perform the following test.
1. With the EFIS-D60 drawing power from an external source, allow it to charge its Internal
Backup Battery above 16.0 volts. Observe the voltmeter (to display, use SETUP >
CLUTTR > VMETER). The battery may charge to as high as 16.8 volts, but it is only
necessary to charge it to 16.0 volts for this test.
2. Remove all sources of external power from the EFIS-D60, ensuring that it is operating
off its Internal Backup Battery.
