Thales FMGS - Normal Descent

FLIGHT PHASES
4 DESCENT
6.2. NORMAL DESCENT
To be optimized, descent should be started at the top of descent (T/D)
computed by the FMGC.
It is shown on ND by the white arrow ( ).
On MCDU F-PLN page T/D is shown as a pseudo waypoint; PROG page
provides Time at (UTC) and Distance to (DIST) [3R].
