At
point 20 the speed target automatically changes to 240
knots to a low the aircraft to decelerate to the SPD/ALT LIMIT.

At
point 21 the aircraft is within 20 NM from the destination
(WPT 8) an less than 10,000 feet above the destination
elevation so the speed target changes
to the 10-degree flap
placard minus 10 knots (240 knots). In this example the speed
target
would already be 240 knots, so no change would be
noticed.
At
point @
the
flaps are lowered
to 10 degrees, which causes
the speed target to automatically change to 210 knots, which is
10 knots below the 20-degree flap placard.
At point @ the flaps are lowered to 20 degrees, which causes
the speed target to automatically change to 160 knots, which is
10 knots below the 39-degree flap placard.
At
point @ the flaps are lowered to 39 degrees, which causes
the speed target to automatically change to VREF plus 10 knots.
The speed targets, whether manual or automatic, can be flown by
the flight guidance system or the autothrottle system.
Whenever the autopilot is controlling speed, such as FLCH or
VFLCH, the autothrottle controls thrust. The autothrottle
will
control speed if engaged
for all other flight director modes,
except TO/GA.
