Today’s airspace is becoming increasingly more crowded. Airlines and aircraft operators are trying to optimize flight plans and landing approaches to maximize efficiencies, operations, and to reduce costs. These new and ever changing complexities are making it more critical for new and updated situational awareness systems that provide secure real-time location data of other aircraft, instantaneous position reporting, and reliable detection of hazards such as terrain, traffic, and weather. Since 2001, Performance has been involved in the development of Transponder and Traffic Collision Avoidance System (TCAS) applications and software upgrades needed to safely and efficiently operate in this ever-changing environment.
