Flight Management System (FMS) for the Agusta AW139/AB139 Helicopter
MCDU PARALLAX ADJUSTMENT
The MCDU is permitted to be adjusted for parallax. The parallax
adjustment feature is used when the MCDU is mounted in the cockpit
such that the pilot does not have a direct viewing angle to the MCDU.
When the pilot does not have a direct viewing angle to the MCDU, the
line select prompts appear out of alignment with the physical line select
keys and is called parallax. Pushing PARALLAX (5R) on the MCDU
MAINTENANCE page accesses the PARALLAX ADJUST page,
shown in Figure 12--1.
When the navigation computer (or performance computer, when
installed) is operating, the PARALLAX ADJUST page is accessed by
pushing and holding the FN key for 5 seconds.
