I have an IFAC on my Flight vest and carry a CAT in my flight suit.
Excellent that you have trauma gear on your person.
plus, some various medical gear that wouldn't do much good in a survival situation
If you have already loaded a patient, or there a serious wounds or other traumata within the crew, the „various (advanced) medical gear and maybe drugs may become lifesaving if the time to rescue gets longer “
We are a medevac/SAR group, so I am intimate with the medical gear on the aircraft (I’m the paramedic).
See that the other crew has at least basic knowledge of first aid, because you may be the disabled person in a crash.
We have not trained at all with the aircraft survival kits. I plan to change that.
Very good, if there is stuff vacuum packed see that it can be opened with one hand (and your teeth maybe) if the need arises. Can the survival gear itself (also your personal gear) be operated one handed, or if you have lesser dexterity and force in your fingers than normal?
I have 3 ways to start fire (matches, Lighter, Magnesium)
Three space blankets (2 in the vest) one in my flight suit.
I have a signal Mirror. But nothing else. I have thought of a PLB for my pack, or possibly a SPOT or other such OTC messaging device. I have been thinking a lot about a strobe. Money is always a concern.
A signal mirror is good, but has its limitations, you can signal never in a northern direction and only in the other directions depending on momentarily stand of the sun.
In tundra (high north) and winter (very short and dim daylight, because of short angled sun over the horizon) may be not so useful. A PLB, a Laser flare, a Strobe / and / or a powerful LED flashlight with strobe or SOS strobe function + lots of spare lithium (cold resistant) batteries are approx. 1.000 $. I attended some funerals where the flower decoration was more expensive… just saying
Mosquito net hat is in my bag as well as lot's of Bug dope.
Saw / Ax is in the aircraft. To big for me to carry on my person or my bag (it weighs a ton as it is).
I do carry snare wire in addition to 550 cord.
I would rather have a filter straw over purification tablets.
The helicopter have VHF handheld radios. While not in my bag...I plan on wearing one on my vest when on missions to communicate with the chopper when I am out with a patient.
One of my biggest worries is going down in the tundra in winter. No trees or wood to burn. I imagine lot's of stuff on the plane to burn assuming it's not under the ice.
Most used material in modern planes are fire/flame retardant treated, so they do not burn well! Or if lit soaked with fuel, it will emit poisonous smoke. So never do this in a confined shelter, a fire in the open even with a reflector will not be very efficient to warm you, but the outer side of your insulating clothes if you have some. So better warm your inner by hot drinks and caloric (warm) food. That means a stove able to consume the fuel from the aircraft (kerosene, that also means the burner has to be preheated), a syphon (with a long hose) to extract fuel from the fuselage, a (big) pot to melt snow and a shelter / windbreak in with a stove can be safely operated (Kifaru tipi?). Also warmth equipment as isolating ground mat, sleeping bag and a sturdy cover for the sleeping bag.
Train! Do “wintersurvival” under save conditions, take a course or do a “test run” winter overnighter with buddies in your backyard.
