Simply Put "tradition" it the reason behind eveything. Noone want to
move to something new, even if its better. There are some old time
pilots who don't even use GPS. I just think that pilots don't like
change. This is way Sporty, asa, gliem, and jepp are the only
manufactures that make it. Pilot are afriad to try something new. But
i do think that the new generation will be changing it.
