Airspeed ...................................................................... MAX 230 KIAS
Spoiler / Speedbrake Lever .............................. VERIFY DISARMED

Caution:  If spoiler/speedbrake lever cannot be disarmed, speedbrake 
stop and intermediate notches will not be engaged. 
Caution should be exercised to ensure lever is not 
inadvertently moved to full aft position as this would 
permit speedbrakes to full 60. position. 
Caution:  If damage to landing gear is suspected or if previous gear 
malfunction has been indicated, do not recycle gear as this 
may cause further damage and make it impossible to 
re-extend gear. 

ALL HYD PUMPS Switches..................................................... ON, HI
