|
|
# if on ground park brake off AND NWS not in 'tow' position, ie off
|
|
# if in flight: both masters ON or OFF
|
|
# the above AND 500 psi diff between green and yellow
|
|
# cargo door operation and YELLOW P/B OFF inhibits PTU operation. PTU op is not allowed for 40 sec after cargo door opr
|

|
|
# powers blue system if no elec or no engines

# deployed if AC BUS 1 and AC BUS 2 are lost

# also deployed manually
|
|
# OHP -- on HYD panel powers the HYD
|
|

|
|
# When cargo door open or closed by manual system it turns off the other yellow system except for altn braking and no 2 reverser

# Priority Valves --
|
|
# Priority valves are there to shut off HYD availability to anything that uses a lot of HYD power if the fluid becomes low

|

|
