Just watched the latest update on an US cable network... Honestly, some of the silliest posts on this board that the mods have deleted bear more weight than the crud they are dispensing
BTW: several posters have commented that they are required to switch the transponder from TA/RA to TA In the event of a depressurization.
There is a damn good reason to do this. If another aircraft is in your flight path as you hit the deck, and you are both in TA/RA the TCAS solution might be to have you climb ( not likely you're gonna do that ) and the other aircraft descend. IMHO, this is adding to the workload in an emergency, and I can't think of a reason a cabin baro switch couldn't do this for you...
Once we figure what happened, I DO think we as the aviation family need to kick some ideas around. Any step we can eliminate in an emergency procedure allows more time for the drivers to fly.
