Popularity of aircraft - dependent from country

Hi,

one factor for the rating is the popularity of the aircraft which is always "constant" (high) and (in my oppinion) just a rough basic number.

Why not add a "national" factor? I think if an airline would grow in the US with a majority of russian or even chinese airplanes, their image would be lower. Or else: if you play in Brazil, Embraer would maybe give an increase in image over Bombardier or others..

Short:

Give an "bonus" for popularity for the country (or countries: Airbus :/) of origin for the plane manufacturer...

Sounds difficult from a programming perspective to me.

sounds almost impossible, not to mention how do you determine which aircraft is popular?  Then there is the idea of do people really care which type of aircraft they fly?  Granted some of us who are aviation enthusiasts but Mr and Mrs general public just want to get to their destination.
