Unfortunately, there are too many stories of pilots who did a great job of getting the airplane on the ground but then died before they could be rescued. Most often the cause of death was from exposure to the elements, and the inability to stay dry and warm. The need to avoid hypothermia is one of the most critical issues we face when having to survive after a forced landing in any remote or inaccessible area, including in a ditching.
If we have to ditch our aircraft, be it in a lake or perhaps even the ocean, it is quite possible that swimming to shore will be out of the question. We’re not going to be able to keep dry, but there are things we can do to keep warm and stave off the onset of hypothermia. The need to assume the “heat escape lessening posture” (HELP) is critical. This position is assumed by holding your arms tightly to the sides of your chest, crossing your forearms over your chest, and drawing up your legs and crossing them at the ankles. This position closes off most major heat-loss areas. If there are several people involved, huddling close, side to side in a circle, will also help preserve body heat. If you have a hat, put it on, because the head is a major heat-loss area.
If you will be flying beyond gliding distance to land, it is wise to have some kind of life jacket on board, or better yet on body. SOSpenders are a type of life jacket that can be worn while flying, without limiting any body movements. Be sure not to inflate any life jacket until you have evacuated the aircraft.
There are five ways that the body can lose heat: conduction, convection, radiation, respiration and perspiration. So if able, provide insulation between your body and the ground as you wait out your rescue, avoid wind chill, stay under cover even if all you have to shelter you is a portion of a wing, and remember that wearing a hat and scarf will ward off radiation cooling. Also, do not overexert, as you will lose body heat through both breathing heavily and getting wet from perspiration, which will evaporate, thus chilling you all the more.
There are five basic survival skills, and learning these, as well as practicing them, will go a long way in helping you to create a plan of action. These skills are:
1. Making Fire
The ability to stay warm and dry is paramount to survival. Even if you have become wet, if you can build a fire, you will be able to get dry and warm. Thus, you should include at least two, if not three, ways of starting a fire in an emergency kit. Between waterproof matches in a waterproof container, a butane lighter and a “FireSteel,” you should be able to start a fire anywhere, any time, no matter how adverse the conditions. Fires will not only help dry wet clothes but also keep those wild critters at bay, and they can aid searchers in finding you, with the light and smoke they create.
2. Providing Shelter
Being able to protect ourselves from heat, cold, rain, snow, sun and wind, as well as from insects and other creatures that can do us harm, is compulsory. Clothing appropriate to the environment you might find yourself surviving in, rather than the environment of the FBO or hangar where you started your flight, needs to be available. There might very well be enough of the cockpit left to provide protection from the elements, but if not, a lightweight, reflective “space blanket” or tarp can add another level of sanctuary.
3. Acquiring Water and Food
The body can survive for quite some time without food; however, without water our survival time is drastically reduced. Certainly carrying water on board will help, but we might have to survive on water that we find. If that water is contaminated, we won’t be able to use it until we purify it. If at all possible, boil it, killing any disease organisms that might be present in even the cleanest-looking water. Second best choice is to filter or chemically treat the water with purification tablets. As for foods, those that have a high calorie content from carbohydrates and fats are much better than those filled with sugar. If you don’t have some in your emergency kit, it is hoped your ancestral hunter/gatherer roots will kick in.
If you have not filed and opened a flight plan, getting found and rescued will depend entirely on your ability to signal rescuers. Replace your 121.5 MHz with a 406 MHz unit, and know how to activate it manually. Even if you haven’t upgraded the emergency locator transmitter, carrying a personal locator beacon (PLB) such as a SPOT or Spidertracks device could significantly hasten your rescue. Always carry some kind of signaling mirror. And an inexpensive GPS can prove invaluable, too. Other ways of signaling include whistles, flare guns and satellite phones.
5. Applying First Aid
Even if you have done a superb job on your forced landing, the possibility of injury is going to be present, so having a basic first-aid kit on board the aircraft makes a lot of sense. Also, if you or any of your passengers are taking any medications, it would be good to have several days’ supply of those in the kit. Panic could very well be your number one enemy if you have had a forced landing in a remote area, and so first aid for your mind and psyche needs to be considered as well. Stop, sit, think, observe and plan your best course of action, as a mental “first aid” treatment at the very outset.
Just as we need frequent recurrent training to keep our flying skills at their very best, we should also consider spending some time with a periodic review of survival skills and techniques. Perhaps on a seasonal basis remove the basic survival kit that you should be keeping in your airplane, and replace any items that might have expired or spoiled or that need refreshing, or that aren’t appropriate for the season. While you have the kit out, refresh your skills in using the emergency tools you keep in the kit. A signal mirror and fire-starting tools are of no value if you have forgotten how to use them.
Aviation has built-in risks, but by utilizing as many risk management tools as we can, even when the worst-case scenario occurs, if we have prepared ourselves through proper initial and recurrent training, our chances of surviving to fly again should be excellent.
