4. D. (5) (a) Climb Phase
Climb speeds can be altered on the following CD-81O CDU pages:
● Initialization climb speed - PERF INIT 2/5 or CLIMB PAGE
. Constraint speed - FLIGHTPLAN X/X
. Restriction speed - PERF INIT 4/5
Climb speed
rules:
. Rule 1 -
Speed constraints > initializationclimb speeds are
ignored.
● Rule 2 -
Speed constraints < initializationclimb speeds are
honored until the constraint waypoint is sequenced. Once
the constraint waypoint is sequenced the target speed
returns to the initialization climb speed.
. Rule3 -
Initialization climb speeds can be changed at any
time and will cause the active target speed to change if no
speed constraint is active.
Figure 272 shows the climb phase of the flight. The following
paragraphs refer to the circled numbers shown.
