Why do "commercial jets", even the newest ones, with tripple multi million dollar IRS systems, lack synthetic vision on their PFD.
On my crummy little 2017 Cessna 182, I have dual GPS navigators, I also have a flight director and a Magenta Line just like the big guys. Only difference is, I can see the hills around me, the big jet crew can't. I can see the hills on my PFD with Synthetic Vision, and I can see them on a 2nd, independent system...EVS and it's only really a budget system, not like the units fitted to G650's but it does work. I always know where the hard stuff is in relation to my magenta line.
So why should I have better SA in a 400,000 Cessna than the guys in a $300 Million 748.
