. Non-standard altitude or speed restrictions requiring a careful energy management:

. An agreed strategy should be defined for the management of the descent, deceleration and stabilization (i.e., following the concepts of next targets and approach gate);

. This strategy will constitute a common objective and reference for the PF and PNF.

X.2 Detect Defined excessive-parameter-deviation criteria and a defined stabilization height provide the PF and PNF with a common reference for effective:

. Monitoring (i.e., early detection of deviations); and,

. Back-up (i.e., timely and precise deviation callouts for effective corrections).

To provide the time availability and attention required for an effective monitoring and back-up, the following should be avoided:

. Late briefings;

. Unnecessary radio calls (e.g., company calls);

. Unnecessary actions (e.g., use of ACARS); and,

. Non-pertinent intra-cockpit conversations (i.e., breaking the sterile-cockpit rule).

Reducing the workload and cockpit distractions and/or interruptions also provides the flight crew with more alertness and availability to:

. Cope with fatigue;

. Comply with an unanticipated ATC request (e.g., runway change or visual approach);

. Adapt to changing weather conditions or approach hazards; and,

. Manage a system malfunction (e.g., flaps jamming or gear failing to extend or to downlock).

X.3 Correct Positive corrective actions should be taken before deviations develop into a challenging or a hazardous situation in which the only safe action is a go-around.
Corrective actions may include:

. The timely use of speed brakes or the early extension of landing gear to correct  an excessive altitude or an excessive airspeed;

. Extending the outbound leg or downwind leg.

X.4 Decide If the aircraft is not stabilized on the approach path in landing configuration, at the minimum stabilization height, a go-around must be initiated unless the crew estimates that only small corrections are necessary to rectify minor deviations from stabilized conditions due, amongst others, to external perturbations.
