You are right Poonpossum, I don't want to upgrade avionics I want to upgrade aircraft.
Crunching numbers with the ever increasing number of AD's on old 206's and now with the SID's, if we are knocking out 1000 to 1200 hours a year per aircraft, we can make payments on a newer aircraft less than 5 years old with just what we save in having quicker 100 hrlys with less AD's etc and smaller maintenance bills and time offline. Want something less than 5 years old as the SID's will kick in again 15 years and hope to be able to replace again in 10 years at 10 to 12,000 hours.
However trying to find low time less than 5 year old aircraft without all the wiz bang electronics just isn't possible as now they all come standard with G1000. I just want a ute. Same seems to apply to the Airvan as they are also going more glass.
