Default Bailing Out Of A RV6

The question has arisen as to whether or not it is possible to open the canopy while in flight. Specifically, can the slider on a RV6A be slid open while in flight in order to bail out? Has anyone had a slider open on them accidentally? Has anyone bailed out of a RV?
This all has to do with aerobatics and whether or not it's possible to bail out...I mean we all have parachutes-right? :-)

Not if we are solo...

I would be more concerned with a typical GA pilots ability (or lack thereof) to stabilize in freefall and deploy said chute.

Round chutes for those non-freefall trained.

What grip length for the 3/16" diameter PIP pins?

Default Bailing Out Explained-Somewhat...

Ok, according to a Ron Schrek webinar I just watched, parachutes are not required for solo aerobatics, but they are recommended. He also describes changing the bolts that hold the front of the slider with quick release pins. There's a lot more of very helpful information about RV aerobatics on his webinar which can be found here:

http://www.eaavideo.org/detail/video...-rv-aerobatics

This webinar is designed to simplify and encourage RV pilots with aerobatic airplanes (-3, -4, -6, -7, -8) to fly aerobatics as he believes it will make us safer pilots.

Not to mention the FUN factor.

Thanks for your responses.

I know over the span of five decades several (5+) glider pilots that have bailed out with little or no training and most made it.

Most of them did not use the static line cockpit attachment that is (was?) used in Europe and hence were freefall.

>I know over the span of five decades...

I know of SIX successful bail outs in the past 4 months alone. While two were test pilots at Mojave and may very well have jump experience, the other 4 did not. Being an experienced skydiver will add immeasurably to your opportunity for success and body position _is_ important, but the basics still apply: Get clear of the aircraft, LOOK, REACH and PULL.

Slider can't be fully open in flight at speed. You need removable forward pins on sliders. When we say bailout, we are taking round emergency chutes for glider/sport/aerobatic/warbird pilots, round emergency chutes, not the skydiving square parachutes you can steer and flare. FORGET THAT. The latter requires real training. The round emergency chute needs little training, because it has slow forward speed and can't stall it, but even emergency round chutes do need some forethought....

This sounds obvious but you need a chute to bailout. Many people own emergency chutes and leave it in the hanger. They get them and don't use them. Chutes are kind of heavy, little bulky, not super comfortable to sit on (compared to that custom upholstery with temper foam). I wore my chute in my RV-4 only when I planned to do aerobatics. However I read of accidents involving catastrophic fire, the pilot perished, their chute sitting in hanger would have saved their life. I started wearing it all the time.

I sat in on Allen Silver's Seminar at Oshkosh about 20 years ago on Emergency Chute for Sport and War Bird Pilots (non jumpers)... There were so many things I learned I never considered. You need to practice and think about it on the ground and repeat mental pre-brief, so when it happens you are ready. This is Allen's page. (If you get a chance to hear him talk do it.)

http://silverparachutes.com/

Allen is Mr. Parachute. He has packed 40,000 chutes and is well known in the parachuting hobby, especially in California. Not saying you need to do an actual jump but consider:
A) Recognize need for bailout
B) What do I do
C) How do I do it
D) Physically doing it

1) Can you get in and out of plane on the ground with chute on? (PRACTICE) Many pilots take seat belt off and then chute and leave chute in airplane seat (typically a thin back pack type). You can do that but practice getting in and out with chute on time to time. Also practice pulling your head-set off or and doing dry runs. Also learn how to put it on properly and learn how to get out of it fast, like making quick releases from how you route straps in the buckles. There are quick releases you can buy, but it cost more. I had a Paraphernalia SOFTIE regular backpack (the shell) with a military 28' chute (C-9). It was good for 250 lbs and 180 mph (more than terminal velocity). This was more chute than needed but got a good price on it. The Para-Phernalia, Inc Mini-Softie or Micro-Softie is a good choice with 24' chute... This is thinner, lighter than my rig. The prices have are not cheap. Expect to pay north of $2000.

2) How high do you need to be. If plane is going straight down at 200 mph at the ground and you depart plane, you will need thousands of feet AGL. If you are level or slightly climbing upright at 1000 feet AGL you can get out and survive. It is the arch of trajectory. The FAR's specify max time for a chute to fully deploy is 3 seconds which is 300-400 feet if you are starting at zero vertical velocity. However practically if we are free fall speed already, we are talking 600-1200 feet. So if you lose an engine at take off and not at pattern altitude level...a jump = bad things. With that said see #3 next...

3) Do you stabilize and then pull D Ring? No get out and pull. You are not a sky diver, no time to "stabilize". Jump and pull. Do it. Don't delay.

4) Practice with ground simulation pulling D-ring with BOTH hands together... You never know you may break an arm. When I had my chute repacked they let me pull the handle and pop the drone chute. A spring launches it out the back. The D-ring is under velcro flap btw.

5) There is little to no steering with emergency chute, but you should know where the WINDS are coming from and turn into the wind ideally. (Forget a sport parachute, that takes a lot of training, practice and signoff... it is not for amateur).

6) Land feet together knees bent... and roll. You will be coming down at a pretty good clip with a small emergency chute.... it's like jumping off the roof of full sized SUV or truck...

7) If you don't have quick release chute harness there is a way to route the straps through the buckles so you can pull on the end and release them, so if you get on the ground and dragged by winds you can get out of chute.

8) Have your cell phone or SPOT on your person and secured (strapped to your body or Velcro closed pocket). You may end up hurt, in a tree. You need to alert people where to come get you.

Just be aware.... and give it some pre-thought and then go through practice drills often... Also remember you can't legally do dual aerobatics unless you both have a chute (with exceptions). Solo you do not need a chute.

In all the glider training I did it was always stressed never to do this.

In an emergency situation you might simply follow old habits and release both your seat belt and your parachute harness as if you were simply stepping out of the plane on the ground.

Unfortunately it has been reported to happen.

Put up with the awkwardness and put the parachute on/off outside the plane every time. Make it a habit.

If you plan to use pull pins on the canopy, make sure they stay lubed and free. When I needed to remove my canopy during the build I found the rollers stuck in the frame and had to remove the tracks to get them free. Probably worthwhile to pull and relube every annual.
