My approach is to take my approach has been to take my normal
EDC kit and start paring it down.
I start by removing the sharps and other prohibited items and place those items in checked baggage. I remove everything that might cause an issue, not just the specifically prohibited ones. So, for example, I remove the safety pins, safety razor, etc.
All fire starting equipment that isn't specifically prohibited goes in checked luggage.
Then, I further pare down the kit removing spares and items that might give TSA an excuse to hassle me. So for example, I'd probably check or remove my scanner and/or GRMS if I was carrying it and reduce the number of spare batteries. I limit myself to two flashlights carry on and anything else goes in checked luggage (I tend to have a flashlight, a backup and a headlamp in my kit).
Then, I pull all liquids and gels and put them in a Ziplock. This caught me off guard last time because I hadn't flown since the whole liquid/gel thing. I forgot that several items in my FAK could be considered a liquid or a gel. When in doubt, into the baggie it goes.
I also ditch any water and obtain some later after going through security (you can't take it through security any more).
I also repack my bag from the Jumbo into a day pack. This allows me to add some warm clothes, rain jacket, hat, etc.
I also spread all the electronics out so they are not "piled" on top of each other (from the xray's point of view). If your junk is piled on top of each other so they can't see through it all or if it is jumbled on the xray then you are begging to ask for "special treatment" IMO.
Prior to getting into line at the security check, I remove any metal items (watch, ring, flash light, spare batteries) and put them in the back, including my wallet. I take my ID, cash and credit cards and stick them in my pocket. I tend to wear steel shank hiking boots on flights, and I unlace them and tuck the laces into the boot prior to getting in line. If I'm carrying a laptop, I'll pull it from the pack and hold it. Ditto the "liquid/gel" Ziplock.
This allows me to stay dressed until I get the the check point at which time, I can easily take off my boots and belt and put them on the xray. I think that you want to make it smooth when you get to the security checkpoint, but not look like you have prepared too much either.
After getting through security, I get dressed again.
My main preparations in regard to a potential crash is to wear sturdy boots, non-flammable/meltable clothes and have a bright flashlight in my pocket. I figure the biggest issue is exiting the vehicle in the event it actually makes it down. If something happens, assume you'll need to leave your back so have it on your person.
In general, I like to have my carry on kit aimed for getting stuck in some remote airport for a couple of days w/o my checked baggage (think snowed in) and end up sleeping in some concourse hallway. This means I do include comfort items like Tylenol, wet-wipes, iPod, book, etc. It also means I do take a power brick to charge my electronics, although I do also have a 4AA battery pack also.
I think the main issue is to avoid any disallowed or marginal items and look "normal" enough not to cause TSA to work you over.
In terms of true survival gear, I think the biggest issue is getting out of the plane. Typically if a 737 crashes, someone notices. And if you really did get into a "lost" situation, the same EDC that serves you well for spending 48 hrs in an remote airport is probably going to be a good start.
