Re 'Flight Director'.
I'm really used to the FD these days. It's a valuable tool in a lot of ways. One of which is that as it showsthe ideal flightpath, if you're handflying, it shows your deviation from same.
When I started (on Loganair Shorts SD-360) most of our a/c had no FD or autopilot , or nothing.
Yet we still had to hack a CAT 1 ILS to mins and did so all the time..
My handflying then was !!!! hot.
Recently, going into Nice, the autos and FD both went off. Took me a few swerves to get the ILS going properly.
I was a bit ashamed of myself when we'd landed off the same 'raw data' ILS that I used to do 'day in and out' on the shed.
Use it, or lose it.
