PM CHALLENGE PM RESPOND Hydraulics.......................................C+F..................ON & HI, CHECKED Warning: Hydraulic pumps must be set to ON & HI for the landing gear and flaps to function normally.
Place the L and R ENG HYD PUMP switches to the HI position and check both Hyd Press gauges within 3000 PSI green arc. Check both Hyd Fluid Quantity gauges for indication above red line.
Place TRANS and AUX HYD PUMP switches to ON position. This is to provide an additional source of hydraulic pressure in the event of an engine pump failure. Verify brake pressure gauges are normal.

MD804118
The target airspeed to be flown on final approach will be the flaps 40° (28°) 1.3 VS speed (VREF) from the speed card plus a wind additive. The wind additive will be:
.
1/2 the steady state wind plus all the gust factor
.
a minimum of 5 knots, a maximum of 20 knots
Examples: VREF is 130 and winds are 16 gusting to 20. Wind additive is 12 and target airspeed is 142. VREF is 130 and winds are calm. Wind additive is 5 and target airspeed is 135.
Airspeed callouts by the PM will be in reference to target airspeed. The internal airspeed command bug will be set, progressively, to the desired descent, maneuvering, and approach target airspeeds. The external speed bugs will be set to 0° RET maneuvering, 0°/T.O. maneuvering, 15°/T.O. maneuvering, and 40°/LND (28°/LND) 1.3 VS speed (VREF).
Manual or Coupled Pitch Control
If autothrottles are not engaged, set airspeed command bug on target
airspeed and manually adjust power to maintain that speed. If autothrottles are engaged, the autothrottle system (ATS) will reference to alpha floor (1.3 VS in landing configuration) or speed selected with the airspeed command bug, whichever is greater.
Gusty wind conditions: Set the airspeed command bug to a speed 5 knots less than target airspeed. Automatic gust protection will be provided up to a maximum of an additional 5 knots above speed selected with the airspeed command bug. If alpha speed is greater than selected speed, ALFA will display on FMA and ATS will control speed to gust integrated alpha speed.
Steady wind conditions: Set the airspeed command bug to target airspeed. (ATS does not measure steady state winds)
Autoland Pitch Control
With autoland/autothrottles engaged, set the airspeed command bug to VREF + 5 regardless of gust or steady state wind conditions. When conditions require gust additives greater than 10 knots or steady state additives greater than 15, autoland operations should be discontinued.
Maintain target airspeed until initiation of flare. Increased landing distances may result when speed additives are used, depending on headwind component. This effect should be considered in respect to allowing airplane to float. Do not fail to apply appropriate deceleration for existing conditions, utilizing maximum deceleration procedures when necessary. Establish required deceleration as quickly as possible.
