Hydraulic Sys 'a' Failure And Ldg Flap Setting
Hi to all..apreciate your thoughts on the following
In the B727-200 EMERGENCY/ABNORMAL CHECKLIST HYDRAULIC SYSTEM(s) LEAK OR LOSS
after completing the checklist and when the affected system is determined ( either A or B or A & B ) the checklist continues with the advisory items..for example system B advisory items are:
1-check weather,crosswind capability is 19 kts
2-observe yaw damper limitations,avoid turbulence
3-plan flaps 15 landing,use Vref+15 kts
4-inbd. spoilers,upper rudder and autobrakes are inoperative
My question is..is it COMPULSORY to carry out these advisory items?..e.g
is the crosswind LIMIT 19 kts?..more importantly..landing with flaps 15 is to blow the spoilers down to prevent them floating..is it mandatory to land with flaps 15,or it..beign an advisory item..can be disregarded under special cases(rwy length limited)
thanks for all your inputs
