REQUEST
Menu Navigation: UNILINK MENU > ATC > REQUEST
The ATC REQUEST page is used to communicate various flight
operations requests via the CPDLC connection. Each request option
(ALTITUDE, VMC DESCENT, SPEED, etc.) utilizes specific sub-
pages to implement the request.
ALTITUDE
Menu Navigation: UNILINK MENU > ATC > REQUEST > ALTITUDE
Altitude requests can be made for SINGLE or BLOCK altitudes.
SINGLE altitudes are specific, whereas BLOCK altitudes refer to a
range or “block” of altitudes. Consequently, altitude requests will be
made from either the ATC REQ ALTITUDE – SINGLE or ATC REQ
ALTITUDE – BLOCK page.
To make an altitude request – Single Altitude:
1. From the ATC REQUEST page, press ALTITUDE, LSK [1L]. The
ATC REQ ALTITUDE – SINGLE page will display.
