bywarren/Denny, I used up the hangover so will add a little pepper to the chile pot. I don't know how many pilots Tropic or Maya have on staff but I would be willing to bet very few of them,if any, are IFR rated. If a ILS was installed in SP add about $1500/$2500 to train each pilot to become IFR rated. The ILS system plus training could very well effect ticket prices out of sight. JMHO
