Emergency Procedure in a hydraulic faliure situ in Boeing 737?

Question

Hi guys i just cant find any thin on the emergency procedures in case of a hydraulic faliure of a B737!! please help

Answer 1

Should you lose your A and B hydraulic systems in the 737, you’ll be down to the standby system. LE flaps and slats will be available, Thrust reversers and rudder will still be powered. The -300 will have the autoslat function available as well. You’ll be in manual reversion for the ailerons.

You’ll lose a whole bunch of stuff. You’ll be using the alternate gear and flap extension procedures. Use flaps 15 for landing. Fly a normal approach profile for final. Because the airplane will be really sluggish in the roll mode, you’d better make your pattern a bit wide. Steep banks in manual reversion are a bad idea.

Once you’re on the ground, you’ll need a tow to the gate, as the nosewheel steering is hydraulic powered.

It’s been 5 years since I’ve flown this airplane and seen this scenario in the sim. I’ve left out a bit, but I do remember that we were REALLY busy at the time. We should've had a checklist for all of the checklists that we had to run.

I’d recommend having a complete hydraulic failure while you’re parked at the gate. It’s so much easier.

Answer 3

Did you try looking in the emergency procedures section of the AFM. It's all there under hydraulics. You'll need to be more specific though. There are procedures for loss of pressure, loss of fluid, hardovers, pump failures etc. And no flaps and rudders are not electric powered on airliners today.

Answer 4

That would be the landing gear, right ? Crash landing.

A couple of guys were at an airport to check out a Boeing plane when one was coming in with the nose gear retracted.

They filmed it. It landed on the door panels for the nose gear. They held and the engines stayed off the tarmac.

The wing flaps and rudders most likely are driven by electrical motors these days.
