What does the DITCHING pb do? PHB 10.5.4
The DITCHING pb on the pressurization panel, when selected ON,
allows the pilot to close all exterior openings below the flotation
line. This will enhance flotation of the aircraft in case of
ditching. System sends a close signal to:
• Outflow valve (if not in manual control)
• Emergency ram air inlet
• Avionics ventilation inlet and extraction valves
• Pack flow control valves
• Forward cargo isolation outlet valve (if installed)


Is this also "According to CNN"?


Nope. Found it somewhere else on the internet.

Sounds like the news media is clueless as usual about aviation
matters...


So, the above is completely nonsens? The button doesn't exist?
Those inlets can't be closed for ditching?


Actually they can in most arplanes. The 'bus has one that will do the
whole lot in one go, though. Some old Brit airplanes had the same thing.
you know,in case "Gerry snuck up on us over la Manch after a jolly good
thrashing of Dresden"

in any case she's talking sh**. It was a low priority in any case.

Bertie


If she was quoting what the Capt. testified to "we didn't throw the
ditch switch" (or similar) how would this be "talking sh**?

Why is the ditch switch a low priority? Is it operable after the plane
has hit water & is (temporarily) floating?

Low priority compared to flying the plane, deadstick, in a congested
urban environment.

Or would you rather he spend time looking for a button on the panel?

Geez people, if you don't fly the plane or if you allow yourself to
become distracted over minutae you will die. Don't you get it?
"Examination of the wreckage of ill fated flight 1549 along with
playback from the CVR showed the air crew to have been unduly
concerned with the 'ditch switch'". Would that make everyone
happier? Perhaps with the stall warning sounding in the background
along with the final 'oh ****' from pilot?

How about this, while attempting to steer around a sudden obstruction/
incident on the highway why don't you call 911?

This kind of faulty thinking is why people shouldn't be allowed to
have distractions, aka radios, cellphones or talking pax in their
automobiles.

Well it takes 3 seconds to flip the switch, you should know where is
located.

one pilot is flying the aircraft, the other one is assisting and going
through the checklist.


Yep.

Where on the checklist is the instruction to flip this switch?

One may assume that since it was not flipped it was not at the top of
the list and thus was of a lower priority. Flying the airplane and
only those steps necessary to (1) avoid obstacles while (2) setting up
for landing are of high(est) priority.

While correcting for a skid on an icy road you should not be
attempting to change radio stations or answering a cellphone. I would
imagine that checking to be certain the fasten seatbelt sign was lit
was likewise at the bottom of the list.

Really folks have any of you ever been in an emergency situation?
It's amazing how much focus you get on priorities. Flying followed by
landing is priority one and from 3000' in the middle of NYC with no
engines you'd best be flying. First things first.

With engines out, no APU and probably given the timeframe no RAM the
ditch switch may not have done anything.

Reading many of the posts here I'm concerned about my safety on the
highway; far too many people have their priorities out of whack with
flying, can it be any better in a car?

The ditch switch is at the top of the ditching checklist and usually is
a memory item, if you are going to ditch I would say is a priority item.

Airliners have 2 pilots and usually only one of them is handling the
controls, the other one takes care of the emergency and assists the
flying pilot. You say setting up for landing, well if you are "landing"
in water the water, prepare the aircraft for ditching is part of it, a
priority.

Changing radio stations or answering the phone is not part of the
driving, the ditching checklist, flipping the switch is part of the
procedure of landing in the water. The fasten seat belt was probably
already on in this situation.

Never had a bad emergency yet and hope never will, but I train a lot for
it, and the main part of it is follow the procedures for the emergency
and in particular the memory items.

ditch switch may not have done anything.


Do not know if the APU was on or not.
The ditch switch would have had the time and the power to do his job.

Well, if anytime you have something out of the ordinary while driving
you get tunnel vision hang on the steering wheel and forget all about
all the surroundings and the way to operate safely your car you are
quite dangerous too
