Press the key for more than three seconds to erase all the data inserted in the scratchpad. If the
scratchpad is empty, it displays “CLR”.
CLEARING DATA FIELDS
Applicable to:
Clear a data field by pressing the “CLR” key, the scratchpad displays CLR, then select the prompt for
the field you want to clear (3L for example).
‐ You cannot clear all data fields :
• If the field contains data that has a default value or a value computed by the FMGC, the data
reverts to this value.
• Any attempt to clear the defaulted value has no effect.
‐ Clearing a constraint on the F-PLN page deletes both the speed constraint and the altitude
constraint associated with the waypoint.
‐ If you clear a data field that is a waypoint in the flight plan (primary or secondary), you delete this
waypoint from the flight plan and create a discontinuity. The discontinuity can also be cleared in a
similar way.

Clear a data field by pressing the “CLR” key, the scratchpad displays CLR, then select the prompt for
the field you want to clear (3L for example). This results in the creation of a temporary F-PLN. The
function has no effect on the active F-PLN until the temporary is inserted.

DIVERSION TO PREPLANNED ALTERNATE AIRPORT
Applicable to:
This would probably occur at the end of the cruise phase, during descent or go-around. The pilot can
use this method for diverting if the primary flight plan includes an alternate flight plan from destination
to a suitable alternate airport.
When decided to divert to the alternate airport from a given waypoint, simply execute an “ENABLE
ALTN” (enable alternate) revision :
SELECT “LAT REV” at a given waypoint
PRESS the “ENABLE ALTN” key
INSERT the temporary flight plan (TMPY F-PLN).
ADJUST the resulting active flight plan.
