In my distant past I was an extreme outdoor guide. In that role, I learned a few things about survival.
Putting together a good kit is fairly simple. The problem, as has been pointed out is to make sure you have the kit when you exit the plane.
Pack as much as you can in a Nalgene bottle and put a small carabiner on it so you can clip it to your belt quickly, before impact. Be careful with using a vest. You do not want any sharp objects in it that can puncture your skin upon impact. (Do not put any objects in a place that can move under the harness!)
As for what I keep in the plane or on me, here is the list:
Leatherman Squirt P4 knife – Kept in my pocket at all times
Space Blanket
Magneisum Fire Starter
Potable Aqua Iodine Tablets – I would like to carry my
SweetWater purification system but it is bulky.
A cheap compass.
A Survival whistle
A small first aid kit – My wife added sutures and a needle. (It is good to be married to a DVM!)
Basic fishing supplies
Utility cord
In my tool bag there is some fine safety wire which can be used as a rabbit snare. (No need for a gun when a rabbit will run into your trap.)
A couple of power bars that I change out every time I get hungry on a long flight.
That is about it.
One other thing that I have in the plane at all times and have instructed my wife to use is the 496. She knows how to remove it from the AirGizmo, install the antenna, switch it to road mode, and how to navigate on the ground with it.
That last point is important. You don’t leave the GPS on all the time or its battery will be used up quickly. What you want to do is locate your position on the chart using the 496 and then turn the thing off. Pick a point in the distance and walk towards it, only turning on the GPS to verify your position. Repeat as needed. If you are conservative, the battery charge should last a week.
As for how far you can walk. There are so many variables. On gentleman said he thought he could make 20 miles a day. He is probably correct, if the ground he is walking on is level (or downhill) and perfectly flat. Add in a lack of trail (bushwhacking), rough terrain, hills, and he could be down to less than six miles. Add to that the shock of your accident and any injuries, time of year (Very hot or very cold and deep snow) and you are down to just a few miles.
Water is the biggest problem. Remember, the best place to store water is in your body. More than a few people have been found dead with water in their canteens/water bottle. Every time you find water, drink your fill, fill the bottle, rest, and reevaluate your predicament. Move on, only if it is wise to do so.
Remember, it might be best to walk at night, if you are in the desert southwest. As mentioned earlier, you might be better off staying with your aircraft. Use the fuel to keep warm and start a Smokey fire.
The final thing on my list is the ELT. You did mount yours where you can get to it without tools didn’t you? You might be hurt, so getting that aft bulkhead off may not be possible. I mounted my ELT under a small door in the baggage compartment floor.
The door is held shut with screws that have big knobs on them to so they can be removed by hand. The “walk around antenna” is also conveniently located so it can be quickly removed and used with the ELT.
If you are injured, do not leave the wreckage unless a week has pasted! Heck, don’t leave the wreckage for a week even if you are healthy.
Depending on where we and when we are going, we will supplement that kit as needed.
As for firearms, most law enforcement agents are OK with you transporting weapons. Just be careful when you land. Many FBO’s aren’t so forgiving.
Some years back I had a dream of taking the RV up to Alaska. For that future trip I bought a
Kel-Tec Sub-2000 chambered in 9mm. (I already had a Glock 9mm and this carbine uses the same magazines.) It is inexpensive, light, accurate, and goes POW every time I pull the trigger. What more could you want?
(To take down a bear, the .40 version might be better. The good news is the bears I have stumbled across in the mountains all took off at the first smell. Bears have a better nose than eyes.)
Do some research on what foods can be found in the wild. Snake meat is palatable and there is a good chance you will stumble across one.
Other tool that I really like but don’t keep in the plane is a
Snow Peak Titanium Trek 700 Mug. It weighs ounces, even with the stainless steel lid. When backpacking this is and the
REI Campware Utensil Set are the only cooking supplies I take. Many of the dehydrated food packages are surprisingly good and are loaded with calories. Eating them right out of the bag eliminates the need to bring unnecessary plates.
