Question

Which one of the following is not a true with respect to integrated modular avionics architecture?

(a) Reduces weight

(b) Easy maintenance

(c) Hardware independent software

(d) Increased life cycle

I got this question in final exam.

I want to ask this question from Modular Avionics Architectures & UAV Avionics in chapter Avionics System Integration of Avionics

Answer 1

The correct option is (d) Increased life cycle

Easy explanation: An integrated modular avionics architecture system reduces weight as the processors are centralized and relatively fewer components are required. It is also easy for maintenance as each component is a separate block which can be repaired or replaced easily. Modular avionics architecture ensures that the software used is hardware independent and can be updated in the future. However they do not ensure increased life cycle of the components, the life cycle of a component is same if the architecture is modular or any other type.
