Emergency location

Emergency location

A highly radar-reflective fabric has been developed by Massachusettsbased Echo Co. According to Echo’s Harry Shamir, the fabric “has almost zero volume and weight, and requires no maintenance.” The question is how the fabric might be exploited for transport category aircraft. One possible application: a cartridge-initiated radar-reflective balloon for survivor’s use as a backup to the emergency locator transmitter (ELT). After a crash, survivors could open the balloon’s storage canister, extract the package, inflate and launch the balloon. Launch heights of 1,000 feet or more might give much improved detection range for search aircraft in comparison with an ELT trapped inside wreckage. >> Shamir, e-mail r_da@adelphia.net <<
