Exactly! Eventually the acft will sink, but this is designed to delay that process as long as possible. I googled it to see if I could find a better explanation than what I learned during flight attendant school, here it is:
"17. 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)"
Hope that helps!
Thanks alot, that is really interesting stuff. Thanks for your effort.
I think that you will find that most slides can be used as rafts in a ditching (the biggest one is normally for the Captain's use). Incorporated on the girt bar mechanism is a pin which will release the slide from the airframe. And often nearby you will also find a knife that can be used if the quick-release fails.
Ok but I am curious why the captain must have the largest raft, why is this?
I take it that the slides are only fastened by ropes/string, and the pin - thats made of metal right, with a red string attached?
PS - I am trying to learn more about safety features on an aircraft. I don't know why but each month I try to find something new about aircraft (obviously, thats why I am here) and if i forget it...i forget it, ill just have to learn again. Recently I have been trying to find out a little about safety, although I havent been on it long, just since monday. If you want to know why I am reading this its to doo with a book on a/c I have just recently read, PM me and i will explain more.
