OPEN DESCENT
• To activate OP DES pull (right click) the FCU ALT knob after dialing in a lower altitude. OP DES acts
like 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
