The question you have to ask yourself is why? There are probably dozens of reasons why they are sticking to the older systems and a handful of reasons to modernize. It is a lot easier to build new infrastructure (e.g. in the 1950s when air transportation was expanding) than it is to replace operating infrastructure.
