I turn it off on any ship with an ADC.I just spent 5 minutes trying to land near some plants I needed to scan, WITH auto-land. It screwed up so much I just turned it off in the end.
I used to faff about a lot trying to land until I realised that the reason I was losing the blue indicator was that the vertical thrusters were obviously aligned with the ship but the ship’s vertical no longer aligned with the planets causing me to move out of alignment as I thrust down. Eventually I realised the simple way to drop vertically onto the landing point was to orient the ship then go to FA-Off the ship then simply falls to the right spot nearly every time.
So much better than the ADC.
My issue with the Mandalay is that I can’t get used to how much of the ship is below the cockpit that the ground keeps hitting when I am flying low.*
Landing it was pretty much like any other ship barring occasionally having to rotate so that the wing wasn’t hitting the side of something.
*Which is why my current Exobiology ship is the Cobra V.
