Approach and Landing
• use either Flaps 25 or 30 for landing
• establish a stabilized approach no lower than 1000 feet above the
airport to improve windshear recognition capability
• use the most suitable runway that avoids the areas of suspected
windshear and is compatible with the crosswind or tailwind
limitations. Use ILS G/S, VNAV path or VASI/PAPI indications to
detect flight path deviations and help with timely detection of
windshear
• if the autothrottle is disengaged, or is planned to be disengaged
prior to landing, add an appropriate airspeed correction (correction
applied in the same manner as gust), up to a maximum of 20 knots
• avoid large thrust reductions or trim changes in response to sudden
airspeed increases as these may be followed by airspeed decreases
• crosscheck flight director commands using vertical flight path
instruments
• crew coordination and awareness are very important, particularly at
night or in marginal weather conditions. Closely monitor the
vertical flight path instruments such as vertical speed, altimeters
and glideslope displacement. The pilot monitoring should call out
any deviations from normal. Use of autopilot and autothrottle for
the approach may provide more monitoring and recognition time
