Multi-element Instructions that Require Verification
For multi-element uplinks that require input and verification prior to sending a response, the uplink
detail page displays required downlink input fields at right side LSKs, enabling the aircrew to create
a response with minimum effort. The required field(s) may be a selection list with a default value
already selected. Actionable responses (UNABLE, WILCO, STANDBY) may be on the second
page of the uplink detail page. For an uplink that requires one or more inputs, the interface
includes a VERIFY action that present the constructed downlink response and an optional FREE
TEXT field to append to the downlink response to provide explanatory context.
This example shows mandatory time and speed inputs and the VERIFY prompt for a multi-element
FANS response.
Step 1. Initial Page Access
ATC annunciator illuminates on receipt of an ATC
uplink.
When the aircrew presses the ATC function key,
the message detail displays, with the required
inputs at LSK R4 and LSK R5.
Step 2. Response Composition
When the mandatory field values (at LSK R4 and
LSK R5 in this sample) have been entered and
are within required ranges, the VERIFY action
prompt appears at LSK R6.
Press LSK R6 to view the constructed response
message.
Step 3. Verify and comment
The VERIFY RESPONSE page shows the
constructed message with the formatted input
values.
Most VERIFY RESPONSE pages have a free text
field for appending additional information.
Typically, free text can be 1 to 3 lines of text.
Press LSK L3 to add context or justification for
the DM.
Press LSK R6 to send the request. Free text is
appended as an element to the multi-element
response.
