The UNS 1E,  has dual navigation database storage. This allows for one database to be active for current navigation and a second database to be inactive and used for past or future navigation.

The subheading ACTIVE indicates the
database currently being used for navigation. The
INACTIVE database is either an expired database
or a future database. When a new database is
loaded, it automatically erases the inactive
database and replaces it. When the active database
expires,  the FMS upon the next power up will activate the now current NAV database. ACTIVE will now be the
subheading of the newly activated database.
Automatic activation of a new NAV database will only
occur on the ground during FMS power on and self
The need for manual activation of the inactive NAV
database is rare, but can be accomplished by
pressing twice the ACTIVATE line select key. This
will result in the FMS automatically rebooting with
the selected database now being active. Manual
activation of a database can only be accomplished
on the ground and flightplan and fuel entries will be
lost during the reboot.

Fancy stuff   alignment creation

A technique to create an alignment point to be used during initialization for an aircraft in a hangar,  first, park the aircraft just in front of the hangar in a location where a lat/long position can be determined by the GPS.

Go to the align page and give the alignment point a
four or five character alphanumeric name.
Enter the name by pressing the Enter key and the
DEFINE ALIGN page appears.

Press the R2 line select key as if to enter a lat/long. The GNSS POS and FMS1 POS line select key will become
available for selection.

Press the GNSS line select key and the GPS lat/long will be entered.

Accept the alignment point and it will now become part of the pilot database.

On the initialization page with the cursor in the ID field, press the L key. A list of airports and pilot alignment points will be presented. Enter the reference number for the HNGR3 align point and press the E key.

HNGR3 is entered in the ID field and the associated
lat/long is listed below.
A protected company routes database can be created using Universal’s Offline Flight Planning Program. The company routes database must be loaded with the same Navigation data that was used for its creation.
NOTE: A configuration option is available that will clear all pilot defined data at power-up. This feature is intended for airline operations in which the FMS will always power up in a cleared state with no leftover pilot defined data from a previous crew.

The DTU 100 uses one ZIP disk to load the NAV database  A normal load should take approximately three minutes. Lift the cover. It is spring loaded to close after inserting the Zip disk. Once power is applied to the FMS
the DTU 100 is powered and in communication with the NCU.  Use the following procedure to load the NAV database in your FMS.

NOTE: The DISK LOAD and PLT DATA SAVE functions are available only when the aircraft is on the ground.
The PLT DATA SAVE line select key  is a method of transferring data from the FMS to DISK   It is also a method of backing up the pilot data  If a requirement to service the FMS develops, the saved pilot data may be required for reloading of pilot data in the FMS.
CAUTION: Disk format will erase all data on the diskette and prepare it for recording.FORMAT DISK can be used to erase a Zip disk,
thus, making it useable to save pilot data.

Press the FORMAT DISK  line select key on the DISK MENU page and a DISK FORMAT page will be presented.
Pressing the FORMAT line select key will
immediately start the format process.
