4. Special Procedures, Private Procedures and Circle to Land: What’s in Your
Navigation Database?    Back to Top
Universal Avionics’ navigation database contains Instrument Approach Procedures (IAP) that are not published as part of the standard chart set. Conversely, operators may have noticed approach types missing from the database. While navigation data tends to be standard industry-wide, there are exceptions; as discussed in this pdf.

5. Loading navdata into the FMS SCN 60x/70x (Standard DTU) or SCN 602/702 and
earlier (SSDTU)    Back to Top
This pdf walks through the navdata load process when using floppy disks and a Standard DTU, or USB flash memory or SD card and an SSDTU with FMS software version 602/702 or earlier. It also includes information on how to load navdata into two or more FMSs at the same time.

9. I've loaded the new navdata update, but the FMS still shows the old expiration date?   
 Back to Top
Most SCN 60x/70x and later FMSs have dual navdata memory locations--to hold current (active) and past/future (inactive) navdata. If you are loading navdata that has a future effective date (or a past expiration date), it is loaded into the FMSs "Inactive" memory. The FMS automatically activates this new data the first time the FMS is started after 0901Z on the
effective date.
  pdf Checking Nav Data  

10. I did not get a "Check All" prompt after loading the new navdata   Back to Top
The "Check All" prompt will only appear if the new navdata is being loaded into the "ACTIVE MEMORY." This occurs only if the current date is within the navdata's 28 day effective period.

If you load navdata before it's effective date, it is loaded into "INACTIVE" memory. When you are done loading, the FMS will prompt for "Load Next" and "Return."
