whole point is it is not an additional instrument, and it doesnt distract you
I'd be interested in a system which did my WCA and interception angle sums for me ... which I'd assume is standard with glass systems, particularly if you connect them to the autopilot ... and automagically knew my ATC clearances and reminded me where I'd been next asked to report, that sort of thing ... which sort of aircraft <-> controller data link I'd assume is not standard with the sort of systems fitted to spamcans and small airfield towers.
