OPEN DESCENT
To activate OP DES pull (right click) the FCU ALT knob after dialing in a lower altitude. OP DES acts similar
to OP CLB, in that it will descend in an idle descent to the altitude dialed in the FCU disregarding any
altitude constraints.
On the PFD the FMA will show OP DES
On the FCU the selected altitude will show without a white dot next to it
SELECTED DESCENT
For selected V/S descent, pull (right click) the FCU V/S knob.
On the PFD the FMA will show in green VS and in blue the selected vertical speed with a – sign in
between, and a blue ALT beneath it
On the FCU you will show the selected V/S with a – sign to the left of it, and the dialed altitude without a
white dot to the right of it
