Ryan Gardner receives the 2016 Outstanding Young Engineer Award at the Maryland Science Center.<\/figcaption><\/figure>\n

As more aircraft continue to crowd our skies, Ryan Gardner, MSE \u201908, PhD \u201909, has been focusing on ensuring the effectiveness of the Federal Aviation Administration\u2019s<\/a> new collision avoidance system.<\/p>\n

The new system\u2014Airborne Collision Avoidance System X (ACAS X)\u2014is being developed by several organizations under the FAA to help pilots avoid midair collisions when other safeguards have failed. In some ways, it\u2019s the last line of defense in air safety.<\/p>\n

Expected to be operational around 2020, ACAS X uses probabilistic models to calculate potential outcomes more accurately. Its goals: improve safety and, at the same time, increase operational suitability by reducing the number of unnecessary alerts that pilots receive.<\/p>\n

Gardner, who is a computer scientist in the Asymmetric Operations Sector at Johns Hopkins University’s Applied Physics Laboratory<\/a>, is working with a team that is employing formal methods to assess the system\u2019s safety in all possible situations. While most of the team\u2019s work so far has centered on piloted airplanes, its findings will apply to new standards for unmanned aircraft as well.<\/p>\n

\u201cOur primary focus is safety more than the operational side,\u201d says Gardner. \u201cOur goal is to verify that the new system does what it\u2019s supposed to do.\u201d<\/p>\n

The Maryland Academy of Sciences<\/a> recently presented Gardner with the 2016 Outstanding Young Engineer Award<\/a>, in part for his work on ACAS X.<\/p>\n","protected":false},"excerpt":{"rendered":"
