Automatic Dependent Surveillance Broadcast (ADS-B) [1] is a technology that can be viewed either as a complement or as an alternative to current radar-based surveillance techniques. ...Despite its many benefits, this technology suffers from the security flaw of having its messages sent as clear text broadcasts, which makes it vulnerable to several kinds of attacks affecting the authenticity and integrity of ADS-b messages - a problem we addressed with a security framework presented in previous work [2]. ...In this paper, we propose to enhance that initial work by using keyed-hash message authentication code [3] (HMAC) to ensure the authenticity and integrity of ADS-B messages. The proposed improvements include changing the structure of the security-related data and, more importantly, adding a cognitive risk adaptive module.

In addition, the traffic indications were considered to be consistent with actual traffic locations, and the timing of the runway indications was considered appropriate. ADS-B signal loss anomalies due to line-of-sight blockage and multi-path reflections were also observed and noted by pilots.

Materials become design, design becoems function Once things you could hold in your hand, materials have become more design ideas than entities, and the designs themselves are transforming into operational activity. The next steps in flight A look at sero engine and assembly developments as commercial airframe and engine manufacturers begin the biggest battle of all-for next-generation short-haul jet aircraft sales. NextGen Today and tomorrow The FAA has reached a major milestone on the Next Generation Air Transportation System initiative to modernize America's National Airspace System. Stacking the material deck for the 787 Combinations such as composites and titanium being used in future aircraft programs can be very challenging when drilling holes during manufacturing and assembly operations.

Improving power quality Avionics power supplies are being redesigned to reduce harmonic distortion and work with wild frequencies. Think smart As aerospace manufacturers and suppliers continually look for new ways to improve passenger safety and comfort, an increasing emphasis is being placed on the role of advanced, 'smart' interiors. Getting it together The manufacture and assembly of today's aircraft must be in line with market needs and emerging technologies in a challenging business environment.
