|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.

The Navigation Database includes ILS, GLS, LOC,
BC, RNAV, GPS, VOR, and NDB approaches.
ILS facilities (ident, frequency, inbound course, final
approach fix, and end of approach) are included in
the approach database.
The runway database includes magnetic heading,
elevation, approach end lat/long, and length.
Pilot created data can be accessed through selection of the appropriate line select key.

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.

LOADING THE NAV DATABASE
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.
press DISKand see

With the DTU we can also also carry out maintenance functions such as START DATA RECORDING, MAINT DNLD, and FLIGHT LOG.
The disk format function is available for the reuse of
disks when saving pilot data.
CAUTION: Disk format will erase all data on the diskette and prepare it for recording.
Press DISk LOAD and follow the prompts.
