AST Completes FAA Grant Project

09.01.2016

Aviation Safety Technologies, LLC is proud to announce completion of a FAA Grant Project, DTFACT-14-C-00004 entitled “Determining Runway Friction Conditions in Real Time Using Data Obtained from Airplanes during Landing Rollout.”

The project was performed by Aviation Safety Technologies, LLC (AST) personnel with tremendous support and guidance from FAA personnel, carrier and airport partners, and other industry experts. AST executed this project through the use of its commercial prototype system, SafeLand utilizing software scripts installed on carrier partner aircraft to collect data during landings.  AST processes this data with its proprietary methodologies to generate friction information about the runway on which the landing occurred.  The friction information is immediately distributed via multiple paths to provide the National Airspace System with a step-increase in safety awareness and operational efficiency.

AST now has the 6 of the largest US carriers as partners and over 1,000 aircraft, including common Boeing and Airbus models, reporting multiple landings on a daily basis.  The SafeLand database currently holds over 2.3 million landings and is projected to generate over 1 million landings in the next 12 months.

The study validated AST’s methodology and the feasibility of obtaining useful runway friction information in real-time from landing aircraft during normal operations and how this information might be distributed to and used by airports and carriers.

AST in The Wall Street Journal – New System Targets Runway Overruns

09.24.2012

 

Now being tested by four carriers, the technology gives pilots objective, current data on conditions

Today the Wall Street Journal published an article on Aviation Safety Technologies and its revolutionary SafeLand safety technology that helps prevent airliners from rolling off slippery runways. It mentions that four U.S. airlines, including American and Delta, are currently testing the concept.

The article reports that AST "has developed a system to provide pilots with more accurate information about conditions on the tarmac, particularly for landings in bad weather. By automatically retrieving and analyzing data already collected by aircraft sensors and onboard flight-control computers, Aviation Safety Technologies LLC seeks to give pilots what they sorely lack: standardized, real-time measurements of local braking conditions right before touchdown.”

The article also quotes Patrick Doyle, the Federal Aviation Administration’s top runway-safety official as saying: “It’s a wonderful technology, and we are pushing this very hard.” He called it superior to current methods, which can cause delays when specially equipped vehicles are sent to determine surface conditions. “You’re taking that runway out of service for a period of time,” Mr. Doyle says, maybe for as long as 20 minutes.

As the article says, “Early testing highlighted promising safety benefits, and the FAA is now planning a broader study to assess whether SafeLand could improve airlines’ on-time performance at busy airports. Mr. Dahl is confident it can.”
