Ongoing Sequester Will Challenge NextGen, FAA Chief Says

June 10, 2013, 11:10 AM

Continuing annual budget reductions due to the sequester process in the U.S. will make it difficult for the Federal Aviation Administration to complete the enabling programs of the NextGen ATC modernization effort on time, FAA Administrator Michael Huerta told the NextGen Advisory Committee (NAC) on June 4. In April, the U.S. Congress passed legislation that gave the FAA flexibility to reallocate money and help restart one such program, he said. But the legislation stays in effect only for the balance of Fiscal Year 2013, which ends on September30.

Mode S Elementary/Enhanced Surveillance

While traditional Secondary Surveillance Radar (SSR) stations interrogate all aircraft within their range, Mode S establishes selective and addressed interrogations with aircraft within its coverage. Such selective interrogation improves the quality and integrity of the detection, identification and altitude reporting.

These improvements translate into benefits in terms of safety, capacity and efficiency benefits which are key to supporting the future of the high-traffic density airspace. This first step of selective interrogation is known as Mode S Elementary Surveillance.

Mode S Enhanced Surveillance builds upon the concept of Elementary Surveillance and consists of the extraction of further aircraft parameters known as Downlink Airborne Parameters (DAPs). This facilitates an increase in the safety and efficiency of the ATM operations.
