not sure how the craft would know when to emit the contrails, though... might want to ask over in the sub where they are working on the AI...
Only one particle emiter, particle size calculated from aircraft category for smal visual difference between Citation X and Jumbos.

Pressure and temperature are quite altitude dependent.[1]
By doing a Google search for "formation of condensation trails" I found the paper [2]. Which one could probably be boiled down to that all that is needed is an altitude span, a QNH span and a relative humidity span. When those coincides the conditions are met and contrails would form.
