The MCDU [SP] key is used for the space function. UNILINK MENU on MCDU (429 Interface)](https://usermanual.wiki/Universal-Avionics-Systems/10801.Users-Manual-3/User-Guide-1641688-Page-15.png)
![UniLink UL-800/801 FANS SCN 30.X Operator’s Manual 23-20-06.02 5 December 2011 Operations NOTE: This Operator’s Manual includes procedures and functions used in a FANS-Enabled UniLink System. Crews that operate this system must be trained and obtain operational approval from the state of registry. Crew interface is accomplished through the FMS CDU and/or MCDU, utilizing a UASC FMS with SCN 1000.5/1100.5 or later. Data may be entered at any field highlighted by a cursor. The cursor is displayed in the first empty data field. Fields with plus signs (+) indicate information is required. Fields exhibiting minus signs (-) indicate input is optional. If there is no cursor displayed in a data field, selecting the ENTER key will place the cursor over the first enterable field on the page. Data is then entered into the field using the CDU/MCDU alphanumeric keys. In some situations, flight progress and related data from the FMS will be prefilled. Subsequent presses of the [ENTER] key will move the cursor to the next enterable field. Pressing a line select key (LSK) highlights the corresponding data entry field. Selecting [ENTER] when the cursor is in the last data field on the page results in the cursor parking off of the page. Pressing [ENTER] again positions the cursor on the initial enterable field on the page. FMS Input The FMS continuously provides current data to UniLink. Many messages and requests have fields that prefill with FMS flight progress data and computed information. In most cases the user accepts the data for inclusion into the message. It is possible however to change a value by overriding that value with a manual data entry. Manual entries are generally retained until power shutdown, although data that would normally change as a flight progresses will be cleared once the page has been exited (is no longer displayed). Source FMS The crew must ensure that the FMS that is navigating the aircraft (Source FMS) is the same FMS that supplies data to UniLink. The Source FMS is shown on the SOURCE FMS page, accessed via MAINTENANCE > SENSOR STATUS > SOURCE FMS.](https://usermanual.wiki/Universal-Avionics-Systems/10801.Users-Manual-3/User-Guide-1641688-Page-17.png)
![UniLink UL-800/801 FANS SCN 30.X Operator’s Manual 6 23-20-06.02 December 2011 The Source FMS is indicated by an asterisk next to it. Any available FMS can be manually selected by pressing the adjacent LSK. If automatic (AUTO) selection is desired, the SELECTION METHOD LSK will toggle between MANUAL and AUTO. NOTE: It is important for the crew to ensure that the Source FMS is not changed prior to an expected flight plan modification uplink. If the Source FMS is changed prior to the uplink, the flight plan information will need to be transferred to the new Source FMS from the previously designated FMS. Communications Prior to entering Oceanic Airspace (and loss of VHF communications) the crew should suspend VHF and transition to satellite communication (See STATE under VHF DATA in the COMM CONTROL section). Current Time On every UniLink screen above the RETURN option at LSK [5R], the current UTC time is displayed. SEND When the SEND LSK is pressed, the request is placed into queue for transmission. The delivery status of the message appears above the SEND option.

The message latency value is used by UniLink to determine if a received uplink is delayed by comparing the sent time to the system time at which the uplink was received. The delayed status of a given message is displayed following the message text (example): 2211Z KZAK¨ NEW PROCEED DIRECT TO NUCAR (SENT 2205Z – DELAYED) The time stamp that follows the uplink ATC message will include the word DELAYED (“SENT 1234Z--DELAYED”). The crew may decide to respond to the uplink normally or to contact ATC for clarification. UniLink resets the message latency value to the default value stored in the configuration module whenever the aircraft is without a CPDLC connection such as end of flight, commanded termination, etc. The latency value is not automatically reset during a CPDLC handoff.](https://usermanual.wiki/Universal-Avionics-Systems/10801.Users-Manual-3/User-Guide-1641688-Page-57.png)
