Over the past 2 years, I've decided I would keep the AT/AP/FDs at all times. Result : my last sim check was a nightmare. B737-300, 55 tons, no AT, no AP, no FD, on an ILS with only light 20 knots crosswind. I've been lucky the DJ in my back allowed me a second try because the first one looked very, VERY poor. I felt like I was somebody else.
I've completely lost all my sensations and reflexes. Visual pattern very inefficient, if any. This is it. I'm going back to my old habits, i.e. switching everything off as often as possible. I cannot keep on degrading my capabilities in such a way.
I think an airline demanding automatic systems at all times is making the wrong bet on the longer run. I'm ok with clinging to autos in busy TMAs because 4 ears is better than 2. But please, chieft pilots, allow your pilots to keep training up. Or there will be a bill to pay sooner or later.
