Teledyne Controls, a subsidiary of Teledyne Technologies Inc., obtained Federal Aviation Administration approval for installation of its aircraft cabin environment sensor on the Airbus A320 aircraft.This follows by four months the approval of the FAA to use the sensor from the El Segundo subsidiary on the Boeing 737 series aircraft. The sensor allows aircraft operators to monitor and measure air quality in the cabin and cockpit.Teledyne Controls is the aircraft data management business of Teledyne Technologies Inc., the Thousand Oaks aerospace, marine and digital imaging products manufacturer.George Bobb, president of the Teledyne aerospace and defense electronics segment, said that having the sensor, known as ACES, approved for both the 737 and A320 is a significant step forward.“It gives airline executives, engineering and maintenance teams the ability to monitor cabin air quality on a large portion of the world’s aircraft flying today with a solution ready to deploy,” Bobb said in a statement.Multiple sensor units are distributed in the aircraft to capture a comprehensive perspective of the air quality. They measure and record data on airborne particulates including carbon dioxide, carbon monoxide, ozone and volatile organic compounds. The recorded data is stored in the compact sensor units and is automatically transmitted to the ACES Cloud Service portal for processing and analysis upon landing, the company said.Shares of Teledyne (TDY) closed down Tuesday $3.48, or less than a percent, to $441.51 on the New York Stock Exchange on a day when the Dow Jones closed down a fraction of a percent.
