FLIGHT PHASES
12 DESCENT
6.3. VARIATIONS
Early Descent (Descent before T/D)
If descent is started within 200 NM from
DEST, FMGS transitions to DESCENT
phase.
If NAV mode is engaged, managed DES
mode may be used.
Ex: start descent at 35 NM to T/D
FCU ALT............... Select/Push
− FMA switches to MACH / DES,
− Target speed drops slowly to lower
part of the managed speed range,
− FMGS adjusts thrust to maintain 1000
ft/mn rate of descent,
− Vertical deviation symbol moves up,
− ND: The "broken" blue arrow( )
shows the intercept point where the FMGS profile will be rejoined,
− PROG page indicates VDEV [2R] from computed profile.
