B737 Hydraulics Queries
My Q's relate to the NG, however I don't think there is a lot of differentiation between that and the classics?
First of all I have read that a number of hydraulic fuses are installed within particular hydraulic lines in order to preserve fluid for other components should a leak develop. Are these restricted to the braking system (normal and alternate) LE flaps and slats, nose gear and thrust reversers? If so, why is this? Is the chance of fluid escape rate greater?
Secondly, the PTU operates when a drop in pressure output from the B system EDP is sensed (among other factors). Is the PTU just additional redundancy for autoslat operation i.e in a stall scenario?
Thanks guys for you input
