Ok. Laugh at me now. Ha...ha. But I'm thinking. I have a 48 year old airplane. I have an inflight fire. I open the door and jump out. What about having a personal parachute in the plane? I'm going to get some aerobatic training anyway, why not?
Anyone have a parachute in their plane?
I was a flight test engineer for the Navy for the first 13 yrs of my career. I can count on one hand the number of times we wore chutes in anything other than an ejection seat equipped aircraft (did not fly the T-34 much). Only times when we did things at very high altitudes in helos (19,600 in an H-60), aft rotor stalls in an H-46, or low g maneuvers in teetering rotor helos (most Bell products).
First recommendation: Smoke Hood. These are typically mylar coated plastic bags that go over your head. Some have filters, some are just a clear bag. The bag keeps what little clean O2 you've got by your nose and keeps the nasty stuff from your eyes. Smoke will quickly incapacitate you. A hood will give you time.
There's a fairly famous NASCAR aircraft crash caused by an electrical fire. Might be worth reading the accident report. Being able to see and breath, even used air would be an enourmous help.
The comment on planning the bail out is excellent. The Navy won't let you go flying (unless you're just a passenger) without practicing. We had to do all the same escape stuff, dunckers, etc as the pilots. Sit in the plane. Visualize a reference point to grab. Never let go until you get you next known reference. (You may have to go for more than one to get out. Practice the motions. This applies if you're on fire and trying to get out or ditched in the water and flipped over.
Getting out of a fixed wing aircraft that is still flying would be tough. Many acrobatic aircraft that I've flown in had a way to quickly release the front door hinge. I'm pretty sure one of the demo helo's had a similiar set up. Bye Bye door!
I know of two guys who have parachutted from helos. Lynn Friesner, Boeing Vertol chief test pilot, parachutted from a dying H-47. (He wore a chute in everything he flew.) (Lynn had the good luck to survive three aircraft destructions, including one of the first V-22 crashes).
The other guy was in an Army cobra at the Navy Test Pilot school (all rotary wing test pilots go to the Navy school). He was leaning down in the cockpit to set a control fixture. "It got very windy. I picked my head up and the top of the cockpit was gone, and so was the main rotor (mast bumping). I release the seat belt, pushed away from the aircraft and pulled the cord."
Why was that important? Because when you'll need the chute will be when things have gone horribly wrong. I think about the Cirrius that hit the glider tow line a few months ago. The video shows a smolding aircraft slowly parachutting its way to the ground. My first thought was that they would all be gone from smoke inhalation if they weren't kill in the impact. I think the smoke hood would would come before the chute.
Chutes aren't that uncomfortable once in the aircraft, assuming you can move the seat back. They are kind of odd to walk around with. They also need maintenace (90 days?).
If you want to think risk management, How high do you fly? If you're on fire, it can take 15 min to get down from 20K. That's an eternity in a smoke filled cockpit.
Hope this helps.
