Why ENG DUAL PROC does not require to switch on Y ELEC PUMP when APU is avail? We lost G and Y HYD SYS so can we recover HYD SYS by using Y ELEC PUMP? I asked you due to FCOM ABN HYD G+Y SYS LO
PR asked:
If yellow sys lost by ENG 2 PUMP LO
PR:
YELLOW ELEC PUMP..................ON
And what does it mean "IF HYD NOT RECOVERED" in PRO-ABN-70:
STATUS page
.............
APPR PROC
IF HYD NOT RECOVERED:
FOR LDG............................................... USE FLAP 3
?
So, can HYD SYS be recovered by Y ELEC PUMP or by airflow when windmill is good?
Thank you!
