Question

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

(a) Federated architecture

(b) Pave pillar architecture

(c) Centralized architecture

(d) Distributed architecture

I have been asked this question by my school principal while I was bunking the class.

The origin of the question is Modular Avionics Architectures & UAV Avionics topic in chapter Avionics System Integration of Avionics

Answer 1

Correct choice is (b) Pave pillar architecture

Easy 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.
