The FBW system on the A320 series is a pretty good system. While nothing is perfect, the protections that it provides makes my job easier. I don’t need to worry about over stressing the aircraft, stalling, over or under speed situations. If you are about to fly into a mountain or an obstacle, the GPWS will scream at you to pull up, and you would select TOGA and pull all the way back on the stick without fear of stalling or breaking the wings off. Nice trick. I don’t know why there seems to be a push for single piloted operations. Every single flight, one of the pilots will make some kind of error. It doesn’t have to be anything consequential or dangerous, but the other set of eyes will generally catch the mistake. If the discussion is about saving money, then it doesn’t really make sense to me. Pilots gain experience flying with other pilots. How will the junior pilot gain the experience to become the only pilot on the flight deck? Watching videos? Flying simulators? Sims are great, but they aren’t going to be enough to give the real experience necessary to achieve the level of safety we all have come to expect. I don’t have a dog in this fight. I will be retired before any of this could conceivably come to pass. I do know that when I fly as a passenger in the future, I won’t get on an airline without two pilots in the cockpit.AIUI the Airbus systems (at least some years back) use 5 computers running 2 different (written/developed by different teams) sets of code (3 on one code, 2 on the other) for exactly that reason.
Failure is still possible, but I've not heard of any.
As these are bread and butter (or maybe waffles and maple syrup) to @321Captain perhaps he can elucidate on the latest 'stuff' with Airbus FBW.
