3.6.6. Distance
Column
Distance between waypoints is displayed immediately to the right of the
path column and is calculated taking into account the associated path as
well as parallel offsets. In the case of a discontinuity, distance between
waypoints is the direct geodetic distance between the two waypoints. In the
case of suppressed waypoints, skipped waypoints, discontinuities or
manual transitions, the distance between waypoints are shown in dashes.
Distance column elements are offset from waypoint identifier column
elements to indicate distance information applies to the leg between
waypoints.
3.6.7. Estimated Time Enroute Column
ETE between waypoints is displayed immediately to the right of the
distance column and is calculated taking into account the associated
distance between waypoints and current groundspeed. In the case of
suppressed waypoints, skipped waypoints, discontinuities or manual
transitions, the distance between waypoints are shown in dashes. ETE
column elements are offset from waypoint identifier column elements to
indicate ETE information applies to the leg between waypoints.
3.6.8. Estimated Time of Arrival Column
ETA at the active waypoint and all subsequent waypoints are displayed
immediately to the right of the ETE column. ETA at the active waypoint is
calculated taking into account the associated time remaining on the active
leg and current time. ETA at subsequent waypoints is calculated taking into
account the cumulative ETEs and current time. In the case of suppressed
waypoints, skipped waypoints or manual terminations, the ETA is shown
as dashes. ETA column elements align with waypoint identifier column
elements to indicate the ETA information applies to the associated
waypoint.
3.6.9. Fuel Remaining Column
Fuel remaining at the active waypoint and all subsequent waypoints is
displayed immediately to the right of the ETA column. Fuel remaining at the
active waypoint is calculated taking into account the associated time
remaining on the active leg, current fuel flow, and current fuel quantity. Fuel
remaining at subsequent waypoints is calculated taking into account the
cumulative ETEs, current fuel flow, and current fuel quantity. Fuel
remaining column elements are aligned with waypoint identifier column
elements to indicate the fuel remaining information applies to the
associated waypoint. In the case of suppressed waypoints, skipped
waypoints or manual terminations, the fuel remaining is shown in dashes.
