Correct Answer : Advanced integrated avionic architecture
Explanation : The Joint Strike Fighter’s sensors, communications, and flight-control systems will blend together more tightly than any other combat aircraft in history, and will revolve around high-speed fiber-optic data buses and powerful commercial off-the-shelf microprocessors using advanced integrated avionic architecture.
Correct Answer : Option (A) : Cost reduction
Explanation : The total cost of sensors used in avionic systems costs around 70% of the total avionic system. IS2 is the concept of an integrated sensor system in which the sensors are shared by different avionic components thus reducing the overall cost.
Correct Answer : Option (B) : Federated architecture
Explanation : Federated avionic architecture is a type of second generation architecture in which the data from each avionic component was converted into digital information and sent to the main frame computer. This technology was called the DIAS or Digital Avionics Information System.
Correct Answer : Option (B) : Pave pillar architecture
Explanation : In a typical single seat fighter aircraft the pilot has to play the role of both controlling the aircraft and weapons management as opposed to a twin seat aircraft where the pilot flies the plane and the RIO or Radar Intercept Officer manages the weapons. Pave pillar architecture allows the pilot to be the weapons system manager without which single seat fighter aircraft like F-22 and the F-35 would not have been possible.
