through cybersecurity and other upgrades to the Aircraft
Communications, Reporting and Addressing System and
Controller Pilot Data Link Communications;
(4) whether the Federal Aviation Administration is
requiring sufficient cybersecurity and electromagnetic
spectrum defenses to address denial of service attacks and
other risks in new technologies it mandates be used on
aircraft; and

Comptroller General.
