           | PLC or relay logic machines, to multifunction keys on the
           | human-machine interface display (HMI) before touchscreens, to
           | a fitful few years when people thought it was a good idea to
           | build machines with VB6 and various serial to digital IO
           | adapters, to purely touchscreen-driven machines with one
           | legally-mandated physical emergency stop button (about when I
           | arrived in the industry, the other machines were mostly
           | historic beasts I've occasionally been charged with
           | maintaining), and back towards multifunction keys. There are
           | usually a few dedicated buttons and indicators for common
           | operations (reset, cycle start, control power on, feed hold,
           | feed rate override, etc), that still makes sense most of the
           | time.
           | 
           | I really think multifunction keys are the best of both
           | worlds. As the author of this piece describes, the
           | multifunction display with 20 keys around the outside (or,
           | for CNCs, 10 keys across the bottom of the monitor and 10 off
           | to the right, in a 1-4-4-1 spacing so you can feel exactly
           | which button you're hovering over while you're staring
           | unblinking at a cutter chewing through 5-figure assemblies)
           | is a good compromise. It takes some serious concentrated
           | planning to design a set of keys that are intuitive (top to
           | scroll up, bottom to scroll down, one dedicated for enter,
           | two for context-specific operations, etc), but it gives you
           | the freedom to design relatively shallow but featureful menu
           | systems that you can memorize and get tactile feedback to
           | operate with confidence.

         | A war plane is something you have to operate while it's
         | burning, or while you're bleeding on it, or while you can't see
         | properly because it's full of smoke or someone just blinded you

           | example, the F-35 so engine so engine failure is likely to
           | result in a lost aircraft.
           | 
           | It's basically been decided that we are going to spend silly
           | money keeping a small number of absolutely cutting edge

               | That's simply not the reality of modern fighter jets. The
               | vast majority of time is going to be spent flying over
               | either open ocean or friendly territory. That's been true
               | even if you're only looking at recent combat missions.
               | 
               | Anyway, single engine aircraft are always going to be at
               | higher risk for mechanical failure, yet that's the chosen
               | design. Just look through this list: https://en.wikipedia

               | commercial aviation 4 crashes per year worldwide is a bad

               | a good month.

       | You can learn quite a lot about aviation UI experience from

       | Boeing-777X ones.
       | 
       | It is not great, actually. PFD (primary flight displays) are
       | cluttered and information-noisy. HUD is a much better tool for
       | flying experience. Fortunately for civilian pilots, this is
       | becoming more common now.
       | 
       | FMS (flight management system) has all the usability of IBM
       | mainframes from 1960s and about the same performance.
       | 
       | The tasks that pilot have to do before the flight are rather
       | simple: you have to input weather conditions, aircraft load and
       | waypoints for autopilot. But with even the most modern FMS it is
       | a tedious and frustrating process, you have non-intuitive control
       | flow and non-qwerty keyboard. Also all text-based, non-graphical
       | interface.
       | 
       | The better parts of aicraft UI are EICAS/ECAM (engine information
       | and alerts) - they are both useful and intuitive to understand,
       | with emphasis on graphical indication.
       | 
       | A lot of hard to use bits are not from any technology limitations
       | - modern aircraft displays are rather capable, but from the
       | decades of industry legacy and expensive certifications required
       | for any change.

             | (transport category) aircraft are CS-25.
             | 
             | So the small jet in my example indeed has less regulations

         | There's also sort of a method of flexing their thighs that they

         | for the rest of the body. That's a bit of an athletic endeavor
         | in and of itself. Try flexing your thighs... now hold them that
         | way for 5, 10, 20 minutes. Yikes.
         | 
         | Anyway, how the hell could you even bark out voice commands

         | time with Digital Combat Simulator. In there you can get first-
         | hand experience with the Harrier and the F/A 18 discussed in
         | the article. You will spend a lot of time with the cockpits and
         | start to develop your own affinity for things in the cockpit,
         | and develop your own ideas about what you like and what you
         | don't.
         | 
         | Do a Google Images search for "DCS FA18 cockpit" or "DCS
         | Harrier cockpit" and you'll see that the real life photos are
         | pretty much indistinguishable from the screenshots, if you take
         | the word "DCS" out of the search term. Every switch and gauge
         | are faithfully simulated, and you can use the real-life
         | operating manuals to operate these simulators.
         | 
         | There's a lot of overlap with a lot of the things I love about

         | making the machines do your bidding. Those types of feelings
         | are much the same (and different) between operating computers
         | and operating aircraft systems. To a large extent these modern

           | In 1983, serving alongside the almost completely analog/60s
           | F-14, the F/A-18 had 3 pretty modern MFDs. Definitely more
