WMU Receives Grants For Aviation Safety Studies
(Press Release From Western Michigan University)
KALAMAZOO, Mich.--Western Michigan University has received three grants totaling $434,690 from the Federal Aviation Administration NextGen Weather Technology in the Cockpit program to study weather information systems to improve general aviation safety and, ultimately, reduce accident risk.
The grants fund three of four Federal Aviation Administration projects aimed at improving the use of weather in the cockpit. The goal is to use the latest weather technology research to improve pilot decision-making during adverse weather conditions and enhance crew awareness.
"The bottom line is that aviation overall has increased in safety," says Lori Brown, WMU associate professor of aviation, who is principal investigator for WMU on two of the research projects. "About two-thirds of all general aviation accidents that occur in instrument meteorological conditions are fatal--a rate much higher than the overall fatality rate for general aviation."
Reducing general aviation fatalities is a top priority of the FAA and similar to commercial aviation, the FAA is focused on reducing general aviation accidents by using a primarily non-regulatory, proactive, and data-driven strategy to get results.
All four of the projects are through the FAA's Partnership to Enhance General Aviation Safety, Accessibility and Sustainability-- PEGASAS--program, whose mission is to enhance general aviation safety, accessibility and sustainability by partnering the FAA with a national network of world-class researchers, educators and industry leaders.
In one project, titled "Visual Flight Rules into Instrument Meteorological Conditions Transition" and funded by a $104,226 grant, Brown and WMU are partnering with Purdue University. In the project's first phase, researchers surveyed more than 600 pilots and conducted focus groups to identify the gaps in weather-related pilot training.
"We wanted to find out how come aviation safety is improving as a whole," Brown says, "but general aviation weather-related accidents are still occurring. We've been looking to find where the gaps are and what we can do to close the gaps."
Brown and her WMU colleagues Bill Rantz, Geoff Whitehurst, Dennis McFall, Dominic Nicolai and Dr. Beth Seiler are developing innovative training modules to construct interactive, computer-based decision trees that can be used by a broad demographic to improve decision making in unintentional transition into adverse weather conditions. They evaluated pilots in late July using flight simulators at the FAA's William J. Hughes Technical Center in Atlantic City, N.J.
Not all pilots are trained in a structured academic program like the WMU College of Aviation, Brown adds. "It can be a different experience, based on where you're getting your training," she notes. "We're trying to develop something that could be available through an electronic link--computer-based training to pilots in the entire nation."
In phase two, researchers are testing pilots who have received enhanced training using events from real accidents, Brown says. Pilots go through training, respond to events, make decisions and then are evaluated and compared with those receiving traditional training.
"In the survey and focus groups we conducted, the pilots themselves, the examiners and the certified flight instructors indicated the gap is the lack of ability of pilots to correlate the weather knowledge that they have," Brown says. "In other words, they're learning about weather, they're learning how to read charts and graphical displays, but it doesn't really prepare them to have the ability to make sound decisions in-flight, to put decision-making and weather knowledge together. That's one of the gaps we're looking at."
Brown's second research project, titled "General Aviation Weather Alerting," is funded with a $158,906 FAA grant in partnership with Texas A&M University. It will look closely at weather technology in the cockpit and weather devices and functions.
"Pilots can get all their pre-flight weather information, their weather pre-flight briefing, and plan their flight, make their go or no-go decision and start their flight and then the weather can change somewhere along their flight and they may not have the ability to have that information while they're en route," Brown says. "We're testing out new ways to alert the pilot when weather has changed."
The College of Aviation is now drafting a proposal for phase three of their research to look at retention of new training modalities in aviation to reduce accident risk for weather-related accidents in general aviation.
The third WMU project, titled "General Aviation MET Information Optimization," is also in partnership with Purdue University and funded with a $171,558 FAA grant. Geoff Whitehurst, associate professor of aviation, is WMU's principal investigator. Whitehurst is overseeing a research team that is investigating the effect of latency or delay due to data transfer rates of NEXRAD information presented to pilots during bad weather.
