Think your Mode-C transponder was expensive just so you could fly into class B airspace? By 2020 you could also have to have an ADS-B (Automatic Dependent Surveillance-Broadcast) installed. As part of the FAA’s “Next Gen” proposal; all aircraft will need to be outfitted with ADS-B to enter class B and C airspaces. I had a chance to use ADS-B while I was in school and found its many uses to be quite helpful. We could pull up real-time weather, be alerted to near by traffic, use it as a form of terrain avoidance, navigate around restricted areas and class B airspace. It was a very nice piece of equipment… I’m sure it costs a fortune. I briefly looked around to try and find a price for purchase and install but had no luck. The price I’m sure is astronomical. The price will not just be high for pilots. The FAA will have to place GBT (Ground Based Transmitters) across the US for the ADS-B to function. All in all, I could see this killing the weekend flyer who is struggling to afford an already expensive hobby. Not to mention rental rates going up with FBOS having to outfit all their aircraft. The FAA is currently looking for comments. AOPA, has more info on their website.

Here is some reading on the Situation:
