There is some upgrades for airliners, some new tech including Auto Land and FBW. The pilots can actually see the runway even in CAT III conditions. The companies will have to go to the CIA in the United States of America in order to arrange the upgrade.It involves Mil-tech which is why installation has to be done in the United States of America but it makes the jet safer when flying....It also does one more thing, it counters turbulence. Boeing jets are getting them!
