Cost reduction

B)

Easy maintenance

C)

Better performance

D)

Software compatibility

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.

Which type of avionic architecture was the first to use DIAS?

A)

Pave pillar architecture

B)

Federated architecture

C)

Centralized architecture

D)

Open system architecture

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.

Which avionic architecture allows the existence of heavily armed single seat fighters with a variety of weapons?

A)

Centralized architecture

B)

Pave pillar architecture

C)

Distributed architecture

D)

Federated architecture

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.
