Ever since Boris Popov introduced his “ballistic recovery systems” (BRS) for small airplanes in 1980, skeptics have continued to question their value. Popov came up with the idea of a whole-airplane parachute after surviving the structural failure of his hang glider, and Cirrus Aircraft subsequently incorporated the safety feature in its SR20/SR22 models. On its website, BRS Aerospace claims 380 lives have been saved by the system, which deploys a parachute that gently returns a disabled aircraft to the ground.

Recently an independent academic study confirmed how capable the system is in saving lives.The analysis, written by researchers from Ohio’s Wright State University and published in the journal Aerospace Medicine and Human Performance, found a 13-fold decrease in the odds of a fatality when the Cirrus Airframe Parachute System (CAPS, developed with Popov’s company, BRS Aerospace) was deployed in an accident, versus when it was not.

Based on National Transportation Safety Board accident data from January 1, 2001 to December 31, 2016, which included 288 Cirrus accidents and 57 deployments, the findings “suggest that [ballistic parachute recovery systems] could play a significant role in the next major advance in improving [general aviation] accident survival,” according to the authors. 

Olson, who got the idea for the study while earning a pilot’s license several years ago, thinks he knows why some still question the value of a whole-airplane recovery system. “When you pull the parachute, you become a passenger, and I don’t know if certain people want to give up control in that situation. They may be potentially overconfident in their abilities, and I think that may be a factor associated with some of that contention.”

BRS deployment

Piloting skill isn’t required in the event of a BRS deployment unless the aircraft is below deployment altitude. Cirrus recommends landing straight ahead rather than deploying the system at altitudes below 500 feet above ground level, among other parameters, including model type. 

Since the study was published, Cirrus has introduced the CAPS-equipped Vision SF50 (aka Vision Jet), but that airplane’s 6,000-pound maximum takeoff weight (vs. about 3,600 pounds for the SR22) may represent the upper limit of current BRS applicability, Kowalski suggests.

“With today’s materials technology, as you get into larger aircraft, you start running into physics that can be very challenging,” he says, noting the 90-foot-diameter canopy of the VisionJet’s parachute is “larger than the wingspan of the Concorde.”

Looking ahead, Popov believes tomorrow’s parachute materials will allow the rescue systems to be used on heavier airplanes. “Graphene level and atomic level materials, much thinner, much lighter and much stronger than today’s,” promise “a quantum leap forward in weight and performance,” he says.

Cirrus’s piston-engine aircraft 

Meanwhile, BRS Aerospace continues making recovery systems for Cirrus’s piston-engine aircraft and a host of light sport, experimental and ultralight aircraft. The company also recently announced an expansion of aftermarket retrofit systems for Cessna 172s and 182s.

Popov is also in discussions with manufacturers of “some well-known larger turbine powered aircraft—six to eight seats,” he says, as well as with manufacturers of autonomous aircraft currently in development.

Everything flying should have some decelerator—I don’t call them parachutes—and I don’t care how,” says Popov. “[Otherwise], it’s like driving down the highway with a car with no brakes. This is simply a braking system.”
