Challenges in the Aviation Industry

Designers Analysts

Metal 5 1

Composites 1 2

Structural Integration

Composites complicate

significantly structural

development,

certification and

production processes.

Systems Integration

Systems development

limited by document based

and “silo-ed” processes.

Thermal/Energy Management

More Electric A/C

leads to

Thermal

Management

Issues.

Verification & Certification

Software –

Structures -

Systems

Certification

becomes

unaffordable.
