The speed control strategy (speed on pitch or thrust) is a function of the vertical flight phase (refer to Table 1-2).
CAUTION: If the aircraft is above the descent path and below the speed restriction altitude, the speed
restriction will not be respected in an attempt to re-capture the path and comply with the altitude
constraints.
The FMS computes vertical speed targets only for descent and approach flight phases. For all other ve
