Anyone knows where to get this freeware addon? It is mentioned in the Aerosoft Airbus manual as a good tool to calculate takeoff performance data but I can't find it anywhere. (Pity TOPCAT doesn't support the Airbus 318!)

 

Or maybe somebody knows another tool or site I could use to calculate this kind of data?

Stumbled upon this, then found your post while looking for a more recent version: http://www.avsimrus.com/f/for-pilots-19/popular-calculator-to-calculate-takeoff-parameters-in-from-airbus-type-36340.html
