 Speed Control


Managed speed
Speed is optimized; constraints and entered
speed data in ACTIVE F-PLN are taken into
account by the FMGS. It is the recommended
descent speed mode.
Target speed is shown by a double magenta
line, but to avoid excessive thrust variations, an
acceptable speed range is determined by the
FMGC and shown as an enlarged speed symbol
(magenta).
