When to use inheritance ?

Inheritance as a knowledge representation model
Does a radar-plane inherits from a plane or from a radar ?
This  relation depends of the point of view :
? for a pilot, the radar-plane is a kind of plane
? for a radar-specialist, the radar-plane is a kind of radar

My aim was to prove that dynamic inheritance could be included in C++. And
to show that dynamic inheritance is useful, we had to discuss about design
decision.
