Want RNAV with that?
As RNAV assimilates all aspects of IFR, even the unassailable ILS gets segments only available to the /G enabled. And even better, you don’t need that pricey WAAS.
Back when Southwest Airlines was the upstart operating out of airports “nearby” major cities rather than in them, everyone in New England knew about Manchester Airport (KMHT). They even call it the “Boston-Manchester Airport,” even though it was an hour’s drive away in a different state.
Now Southwest flies to Boston’s Logan Airport, and KMHT is more a sleepy reliever field. However, it’s still an aviation trendsetter, and this trend is open to anyone looking for more efficiency.
