TAB_E ~
Note : when the speed is selected the pilot can do the switching manually by pressing
the SPEEO/MACH pushbutton on the FCU. The FCU then displays the aircraft
Mach number.
When the target speed is managed, the FMGC commands the switchover automatically
as a function of the ECON MACH value.

MANAGED SPEED TARGET MEMORIZATION
A dual FM failure has different consequences when it occurs in different phases of the
flight. The system handles target speed and SPD mode as follows :
- During approach with LOC and G/S engaged and radio altitude < 700 feet, the target
speed is set to VAPP as previously memorized, and managed SPD target is maintained.
- At go-around, the target speed becomes the memorized go-around speed, which is the
higher of VAPP or the speed when go-around was initiated. Managed SPD target is
maintained.
In all other cases managed target speed reverts to selected, the value being the speed
at the moment of the failure.
SPEED/MACH FCU WINDOW SYNCHRONIZATION
When the target SPD is managed, the SPD/MACH display of the FCU shows dashes.
However, the window displays the target SPD or MACH in the following situations.
- The pilot turns the SPD/MACH selector knob.
If the pilot does not pull the knob within 10 seconds after turning it, the selection reverts
to dashes.
- The pilot manually engages a selected SPD target.
