BRS sounds good, but in practice I would prefer a personal chute every time. If you are in a midair 500 ft above the ground, a BRS will save you. You'd never make it trying to bail out with a personal chute. A Personal Chute assumes you are still a going concern. A friend of mine was hit by a piece of wreckage as he left the aircraft. Had he had a BRS he would still be with us. |

The Genesis-2 was designed for a BRS system, but production was stopped before testing was done. I have installed 36' BRS (1050) systems in a couple of G-2's. Several years back, I came close to a mid-air in the pattern..............I believe a BRS would have offered my only chance of surviving that day, had we hit. Having the little red handle available, gives me a great sense of confidence! At 84, I can hardly climb out of the cockpit, no way wearing a parachute! Add G forces that would be present in a hard-over rudder situation...........? BRS claims their system will work as low as 350'.
Wishing everyone, happy landings, JJ |

Part of why some (me included) feel a static line is good. If you hit the tail after getting out, you may be unconscious (similar to your ship hitting the bottom of another, etc.).
Yes, you may get tangled in the line and it slows/prevents chute deployment. I believe ours is usually 20' or so, enough to clear the tail. It is in a small coil (enough slack from cabin mount to rip cord of maybe 4') with a single wrap of electrical tape to maintain the coil until needed. |

To me the major advantages of a BRS over a personal parachute are the
speed and certainty of deployment.Â* Of course either system may fail or malfunction, but with the BRS, you lose the difficulty of getting out into space and deploying at in unfavorable position. Simply pull the handle and enjoy the ride. But, upon landing in a windy situation, you run the very real risk of being killed in a tumbling, disintegrating wreck being dragged along the ground.Â* Is there a jettison capability that could be armed by the sudden deceleration of landing?Â* Perhaps an automatic jettison?Â* Might that malfunction at 500' and give you a last thrilling ride?

I'm curious about BRS system deployed when the aircraft/glider is spinning. Structural failures or loss of flight controls/wings in a midair could lead to an unrecoverable spin. Would it be better to eject or to hope the BRS won't get tangled by virtue of the rocket pulling the canopy clear of the spinning airframe. I must assume the manufacturers have already considered this.

Plenty have died following a conventional parachute mal- function. The bottom line is that BRS will work at a lower height but is hardly available in any common sailplane on sale today. Retro fitting a BRS to an EASA sailplane would be a expensive, possibly impossible, task. With ultra-light sailplanes it's different. The other major problem, as clearly explained on DG's website, is that "safety does not sell sailplanes". The majority of DG sailplanes sold were NOT equipped with the NOAH system: the new buyers simply did not order the NOAH system. Even if BRS was available today how many buyers would buy it? Dave W |

Dave W If a BRS system were available factory installed at a reasonable price, I suspect that a very large percentage of buyers would sign up. It's a huge selling point if you are trying to get the OK from your spouse to upgrade to a new glider. Offering a BRS system standard on all of their airplanes is probably the #1 reason that Cirrus is now the largest piston engine aircraft manufacturer in the world. |

Cirrus and Phoenix think that BRS systems are important enough that they make them standard and a significant part of their marketing. |
