Applicable to:
The EQUI-TIME POINT page displays the ETP, computed along the F-PLN route between
two referenced positions (airports, waypoints or navaids), defined by the crew (Refer to
DSC-22_20-50-10-25 EQUI-TIME POINT PAGE).
When first accessing the page, the FMS proposes origin and destination airfields, as defaulted
positions.
The crew may overwrite these two positions and insert the wind in their vicinity at the applicable CRZ
FL.
The FMS then computes the resulting ETP, using the managed or selected speed, and blending the
forecasted winds along the F-PLN route with the inserted winds.
The FMS provides :
‐ TIME and DIST from the aircraft position (or origin on ground) to the ETP
‐ The BRG/DIST from the ETP to the defined positions
‐ TIME overhead each position, assuming the aircraft flies from the present position to the defined
position via the ETP
‐ (ETP) pseudo waypoint is displayed on the ND along the F-PLN
‐ ETP location in relation to the subsequent waypoint.

The FMS then computes the resulting ETP, using the managed or selected speed, and blending the
forecasted winds along the F-PLN route with the inserted winds.
The FMS provides :
TIME and DIST from the aircraft position (or ‐ origin on ground) to the ETP
‐ The BRG/DIST from the ETP to the defined positions
‐ TIME overhead each position, assuming the aircraft flies from the present position to the defined
position via the ETP
‐ (ETP) pseudo waypoint is displayed on the ND along the F-PLN
‐ ETP location in relation to the subsequent waypoint.
EQUITIME POINT ENTRY
Applicable to:
PRESS the DATA key.
SELECT the EQUI-TIME POINT prompt.
The EQUI-TIME POINT page is displayed. The origin and destination airports are used by default.
ENTER the REF POINT 1 in the [ 1L ] field.
ENTER the associated wind in the [ 2L ] field.
The wind to be inserted is the wind in the vicinity of the reference point at the CRZ FL.
ENTER the REF POINT 2 in the [ 3L ] field.
ENTER the associated wind in the [4L] field.
The system displays the ETP location with regards to the next waypoint of the active flight plan
following the ETP in the [5R] field, and the A/C TO (ETP) predictions in the [6R] field.

Note: ‐ The ETP pseudo-waypoint is not displayed on the MCDU F-PLN page. In order to easily
locate it, or when closing the applicable ETP, the TIME MARKER may be used ; this
allows the crew to visualize it in advance on the F-PLN page or, to prepare the next
applicable ETP on the Equi-time Point page.
‐ The ETP is computed using speed according to the current mode (managed or selected).

The FMS computes the ETP location (ETP coordinates, and distance between the ETP and
the following waypoint on the F-PLN) and displays it in the [ 5R ] field. The FMS also computes
predictions related to the ETP (the distance to go, and the predicted time at the ETP) and displays
them in the [ 6R ] field.
