I have been in aviation as a mech/tech for about 20 years. Now 40ish and looking at the possibilities of going into aerospace engineering (aeronautical or electrical or...). Basically I am bored of being a mechanic all the time and want to step up to area of design it and figure it out rather than just fix old stuff. I am trying to find a way to justify the expense of going back to school for several years. It will be costly but possibly cost effective over time. The idea of a fun challenge in a new area of aviation is exciting. The thought of it costing me more than I will make back after time spent in school, spending and not making money, is enough to give pause to the idea. I would like to find a few folks that maybe have already done similar and hear from them. I want more from aviation and have invested a lot of my life to it but I am not happy with where I am. It seems then, I should invest in school and go for it. How can I convince myself and my wife with some reasonable degree of assurance that it would be in our best interest for me to be a student for the next 4 to 6 years? Meaning I will be looking at being a new aeronautical/aerospace engineer at the age of 47. The up side is that I will not be new to aviation at 47. Part of this comes from not wanting to be a mechanic crawling around all the time inside of a dirty old aircraft. Which is how I do spend a fair bit of my time now. It has its rewarding times when trouble shooting systems but it will not get easier on an aging fellow as time goes on. In looking at median or entry level wages for engineers compared to my wages there is not a big increase but there is an increase and I am looking for a way to justify the time and money investment. I am not so much worried about being an older returning student. I am fairly well self taught and believe in my ability to succeed in school. Just looking for some input. Thanks for your time. viking42 PS I have been reading some posts here and this seemed a reasonable place to put this. If I should post elsewhere in this forum let me know.
