I just googled average household income. It's CNN so it has to be accurate. lol. Anyway, in 2015 it was 56K. So basically, a Cirrus or Mooney will cost 15 years of a family's entire pre-tax income. If the family goes cheap and gets a 172, maybe they can get by with only 8 years worth of income. The problem is simply cost. Market all you want, but you're not getting the average American family to buy a new certified plane. They simply can't afford it. You're now trying to sell planes to the 1%ers that actually have an interest in flying themselves. I just picked a year (1969) A cessna 172 cost $12.5k, and average household income was $7,330. That's less than 2 years income. Still a lot, but far more realistic. I realize there is a lot more to the newer planes, but I assume regulations, lawsuits and manufacturing costs have contributed to this unbalanced increase. Aviation is simply outpacing the average Joe's wallet.
