Many, many years ago when I joined this august forum, I mentioned my annoyance, nay, outrage at turn and slips being removed from public transport aircraft. I was flamed. I was then told I couldn't control a jet transport aircraft with this simplistic instrument. Strange how I'd flown so many sectors with the horizons shielded - from my view, I hasten to add.
It was one advantage in working for an airline that was going broke. Empty sectors. I've flown more than my fair share of those.
That, now miniaturised instrument is capable of latching on to the fabric of the Universe . . . whatever that might be.
