them.
SID or TRANS selection can be removed by selecting “NO SID” or “NO TRANS”
located at the bottom of the lists.
If a runway or SID was already selected before performing the revision, it is displayed
in green in choices list and in top line. Temporary selected choices are yellow, and
other choices are blue.
Selecting a runway changes origin airport waypoint to a runway waypoint. If only a
runway and no SID has been selected, a “conditional” waypoint is added after runway
waypoint, which instructs to climb straight ahead on runway heading until reaching
1500 ft AGL.
Arrival pages
Arrival pages allow to review arrival procedures (Approaches, VIAs, STARs, Transitions) and enter them into the active ight plan.
These pages are accessed by selecting ARRIVAL prompt on a Lateral Revision page for the destination. Their organization and
functionality is the same as for Departure pages.

Direct To page
Pressing the DIR key on MCDU keyboard brings up the Direct To page. It allows to create a direct leg from aircraft’s present
position to any selected waypoint. This action automatically engages managed NAV lateral mode and the aircraft proceeds direct
to selected waypoint.

Waypoint entry at 1L activates the Direct To function, adding the present position (Turn Point, “T-P”) waypoint followed by entered
waypoint at the top of ight plan.
If the pilot enters a waypoint which is present in active ight plan, all waypoints before this waypoint are removed, and a direct
leg to it is created.
You can also select any waypoint from the list in lines 2-6, which will place the selected waypoint into “DIR TO” eld and produce
the same result as manually entering waypoint name. The waypoint list is identical to F.PLN A page and can be scrolled using
slew keys.
If entered waypoint is not present in active ight plan, it is added on top of the ight plan following by a ight plan discontinuity.

CLB or DES SPD LIM: Climb or Descent speed limit, depending on which ight phase the waypoint belongs to. New speed
and altitude values can be entered. Speed limit can be cleared by using CLR key.
SPD CSTR: Speed constraint for the waypoint. Airspeed is entered as 100..350, Mach is entered as 0.15 .. 0.82. Entry
can be cleared.
ALT CSTR: Altitude constraint. Entry can be cleared.

PERF pages
The ight plan is divided into several phases: PREFLIGHT, TAKEOFF, CLIMB, CRUISE, DESCENT, APPROACH, GO-AROUND,
DONE. Each phase except the preight and done phases has a performance (PERF) page. The PERF pages display performance
data, speeds, and predictions.
Pressing the PERF key on MCDU calls up performance page for current active ight phase. Pages for next phases can be viewed
by selecting “NEXT PHASE” prompt. Pages for phases already own are not available.
The page title for PERF page corresponding to active ight phase is green. Titles of pages for next phases are white

Note: When APPROACH phase is activated, the managed speed guidance will target Vapp speed or maneuvering speed for current
aircraft conguration. If Approach phase is activated by a mistake using PERF pages, the CLIMB phase can be activated by
re-inserting the Cruize FL value at PROG or INIT page.
