The Universal UNS-1 is a very common flight management system (FMS) which is can be found in the Bombardier Q400, Learjet 45 as well as the Boeing 737-500 (retrofit) in Aerofly FS 2 with only minor differences between them. The simulated devices can be used to change the flight plan from within the cockpit, without having to leave the aircraft and going back to the main menu.
Fields on the displayed page are selected with the line-select-keys (LSK) to the left and right of the display. After pressing a line select key next to a field that can be edited the field will be displayed in reverse video (white background). The value can now be edited with the alphanumeric keyboard. When the entry is complete the enter key is pressed to insert the new value. Changing the page or selecting a different field on the page discards an entry.
The information from the flight management system (FMS) as well as other systems such as the attitude heading reference system (AHRS), global positioning system (GPS) and others are presented on numerous pages in the control display unit (CDU). The control display unit (CDU) is the cockpit interface that the pilot use to input data into the flight management system (FMS).
The Universal UNS-1 pages are
The keys labeled LIST, MENU, PREV and NEXT perform functions on the select page. For example the MENU button opens the menu for the selected page, PREV (previous) and NEXT (next) buttons scrolls through the sub-pages.
Deleting The Old Route
To delete any previous route, e.g. the route created with the Aerofly FS 2 navigation menu:
The route is now completely removed.
Enter New Origin
Now the flight plan page should be empty and only the first line should be selected.
The cursor now moves to the next field.
With the cursor at the end of the flight plan you can type in the identifier of a waypoint. For example:
SMOwith the CDU keyboard to add the Santa Monica VOR
For the Learjet 45 tutorial repeat this process for the VORs
You can also see a list of nearby waypoints by selecting a position in the flight plan, where the waypoint should go, then pressing the LIST key. When you find the desired waypoint just enter the list position (not the name) and confirm with enter. The waypoint will be automatically added to the flight plan.
At the end of the flight plan we can add the destination airport ICAO identifier.
KSBAfor Santa Barbara.
Add or Change Departure
With the flight plan page open simply hit the MENU button. From the displayed menu select the DEPART option on the left with the line select key next to it.
Add or Change the Arrival
With the flight plan page displayed open the flight plan menu by pressing the MENU key. Select the ARRIVE option.
1to select runway 07.
Verification and Flight Plan Summary
After all waypoints have been added, step through the legs on the flight plan page with the PREV and NEXT buttons. Check that there are no gaps in the flight plan and that the route is indeed the flight plan that was filed.
At the end of the flight plan pressing the NEXT button will show the flight plan summary. Here you could enter an expected cruise speed (TAS), expected average fuel flow (FF), fuel reserves and the expected time of departure (ETD). (Some of this may not be simulated at this time).
Note - Editing the flight plan like this is optional and always will be. You can always go back to the navigation menu and change the flight plan from there.
