Yes, the technology exists, and no, we don't fully use it. For flight plans, on the 777, we could receive a flight plan enroute to address track/routing changes. Normally, we didn't receive it that way. On the 737, I've never seen it. Radar...no.

We still use logbooks, although we send maintenance messages via ACARS. So we actively use archaic means of business despite the fact all the means to step into the 21st century are at our disposal and operational. A nice little aside is that unsigned pages in logbooks are a hot item, regardless of whether the gripe is signed off in the master maintenance computer.

In the technology "I'll show you mine..." vein, I heard you guys don't do LNAV approaches and still use dive and drive NPAs.
