correct procedure in case of an emergency water landing
We all know about recently miricle on the Hudson river, where 57 years old flight captain Chesley Sullenberger sucesfully ditched boeing 320 into the Hudson river near Manhattan.
But I can't find the data about how he succeeded that hard manoeuvre and what is the correct procedure (by FAA) in case of emergency water landing.
I predict that captain (when he found out that he lost all the thrust), lowered the nose of a plane so he reached best glide speed (190 KIAS for A320), but what he did after that, how he landed on the water?
Did he add full flaps and slow the plane down to Vs0 speed (minimum flight speed in landing configuration) and than maintain normal landing attitude (5-7° nose up with level wings), until the plane touch down the water.
What about the fuel? Plane probably had some fuel, did captain dump the feul prior the ditching. This way plane will be lighter maning Vs0 speed will be lower + it will easier float on the water.
And how come that plane almost completly sinked, isn't fuselage water tight if it is air tight, front doors and emergency exits above the wings where above the water line. Could passangers wait in the plane, until rescue teams will come?

Ditching procedures
Ditching procedures vary.
As per type of airplane, as per airline policies and procedures.
If I read my procedure, it is only correct for my aircraft and my airline.
One thing to remember -
Any takeoff near water, you might be ditching 10 seconds after lift-off...
Crews are well aware and trained for that, cockpit or cabin crews.
And passengers should read safety diagrams first, rather than duty-free catalogs.

Today's Pprune topic is ditching immediately after takeoff.
Last week subject was aborted takeoff and evacuation with fire, Denver 737.
Then before, was BA 777 landing short at LHR with no power....
Knock on wood, there will be no other favorite topic for a few months.
Or just "how to become a pilot" and "who is hiring 250 hrs pilots"...?

With no engines powering the hydraulics, you cannot select any flaps. Only slats.. Even if he had flaps, he would have to maintain enough speed to keep the ram air turbine turning happily in order to pressurize the flightcontrols. So no slowing down!!
In the meantime, the FO would not have working screens, just to mention a few things. Unless they had the foresight to start the APU at the first hint of engine trouble.

Does the A320 FCOM include those procedures????
