Was | great. | | Update: was one of these. https://xkeys.com/ | LeifCarrotson wrote: | My company builds and works with industrial automation, | custom CNC machines, and industrial robots. I've observed a | shift from purely button-and-neon operated panels from early | 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. | nickff wrote: | There are lots of buttons and switches on the throttle and | stick. Most modern western fighters are designed for HOTAS | (hands on throttle and stick) operation, where the pilot never | takes their hands off the throttle and stick during combat. | cccc4all wrote: | The touchscreen is not there for UX. The touch screen is there | to charge $200,000 for basically $500 ipad. | | The software costs for touchscreen probably is in the $ | millions. | topspin wrote: | > I can't imagine the frustration trying to use a touch screen | to fly a fighter jet. | | 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 | with a laser. The adoption of touch screens in this sort of | cockpit seems misguided. Particularly for anything related to | controlling comms or navigation. | Retric wrote: | That's really not how we design modern jet fighters. Air | combat involves a huge number of tradeoffs and ejecting is | now the correct response to a wide range of issues. For | 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 | aircraft flying rather than thousands if not tens of | thousands of of likely more efficient but less capable | possibly drone aircraft. | | PS: To be clear it's possible their making the correct | choice. I personally doubt it, but I don't have access to the | kind of classified documents to justify things in one way or | another. An effective labor weapon for example might render | vastly cheaper drone fleets ineffective. | jki275 wrote: | No, the post above is exactly correct. | | Ejecting from an aircraft is an absolute last resort, and | you stand a good chance of dying or being badly injured if | you have to do it, and even if you survive the ejection, | the parachute ride, and the landing, it's a better than | even chance you're going to be captured and beaten, | tortured, or killed on the ground. That's if you land on | land of course -- if you land in the water you might just | drown or never be found. | Retric wrote: | > it's better than even chance you're going to be | captured and beaten, tortured, or killed on the ground. | | 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 | .org/wiki/List_of_accidents_and_incident.... In | commercial aviation 4 crashes per year worldwide is a bad | year, in military aviation 4 crashes a month worldwide is | a good month. | topspin wrote: | > That's simply not the reality of modern fighter jets. | | Even Iraq managed to capture US and allied pilots. I | think I'll forego the rest; you're reality and actual | reality are a bit too divergent. | d_silin wrote: | You can learn quite a lot about aviation UI experience from | civilian airliners' instruments. I did work a little bit with | 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. | d_silin wrote: | To elaborate on my point. Arcade flight and space simulators | have probably the optimal possible UI for | "aviate/navigate/communicate" activities. | t0mas88 wrote: | Ask any pilot what the most complex part is about switching | aircrafts and getting a new type rating. It's never the way the | plane handles, is always either remembering the mandatory | systems knowledge or how to use the FMS. | | I flew along on a small private jet recently, their system was | 10x easier to understand and more capable than the typical | airliner... So it is possible, probably even at a lower cost. | mshockwave wrote: | are private jets under different regulations (rules)? | bdavis__ wrote: | Yes. Both for pilots and the airplane. | t0mas88 wrote: | It depends on the weight, seat count and type of operation. | Very generally speaking small jets with 9 seats or less and | not being too heavy are CS-23 certified while larger | (transport category) aircraft are CS-25. | | So the small jet in my example indeed has less regulations | than a larger airliner. And would probably not be allowed | to be used for commercial air transport, only charter | flights. | DSingularity wrote: | Wow, how did the fact that the G-forces will make it difficult to | use voice commands or to interact with a touch screen not kill | these F35 cockpit features a long time ago? | JohnBooty wrote: | To be _really_ specific for those not aware, pilots need to do | special breathing routines when under high g-forces. | | Deep, rapid breaths. They need to suck oxygen into their body | as quickly and efficiently as possible to maintain | consciousness, because the g-forces forces blood away from | their heads and towards their legs and feet. | | Here's a "classic" video of a pilot successfully evading an | unbelievable number of SAMs over Iraq. The rapid breathing | might make you think he's panicking. Nope, he's got it 100% | under control and is following training perfectly. Though I'm | sure he certainly needed a drink after making it home. | | https://www.youtube.com/watch?v=qUjX1RntqVw | | There's also sort of a method of flexing their thighs that they | learn. Restricts blood flow to the legs, so there's more blood | 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 | while doing that sort of breathing!?!? | waiseristy wrote: | These voice commands are usually just for changing radio | settings and other non-essential functionality. Stuff that | would be just as difficult to change with tactile switches in | high G. The Eurofighter has been using a similar system since | the 90's | mshockwave wrote: | I only know some standard "anti-G" actions involve breathing | really hard while keeping your lungs inflated. I guess that | makes speaking more difficult? | medium_burrito wrote: | First, I'm curious if they use a throat mike or something bone | conducting. | | Second, given how shitty voice interfaces are, I'm shocked they | would use them at all. I assume the military funds a lot of EEG | research- that would be ideal here. | jandrese wrote: | According to the article the author knows of no pilots that | use the voice interface. | | Given how finicky they are I can't say I'm surprised. Maybe | with modern pseudo-AI systems they could be reliable enough | to depend on, but none of that is in military hardware | specced out 20 years ago. | medium_burrito wrote: | If you used the nato phonetic alphabet maybe, ie shortcodes | for voice??? | jandrese wrote: | It would probably help, but there is still the enormous | noise floor to contend with. Jet Fighters are | unbelievably loud. I mean that literally. If you've never | watched one take off you would think I'm exaggerating the | noise level. It's hard to describe because most people | have never experienced something that loud. | stickydink wrote: | Not sure how much I'd trust my brain for this kind of | thing...

A little | buzzer somewhere in their flight suit might provide pilots with | 'a button was pushed' confirmations. Maybe that would be too | distracting though. | banana_giraffe wrote: | I've missed notifications on my phone on long flights because | I didn't feel the buzzer. I can't imagine a fighter jet is | more conducive to feeling a buzzer than a commercial airline. | | Honestly, I'm amazed the buttons around the edge of the | screen aren't context aware buttons based off which screen a | non-touchscreen display is showing. | jandrese wrote: | It would probably be a little hard to feel when you're | already getting buzzed constantly by the turbine engines and | airflow. | stretchcat wrote: | True... maybe if they could get buzzers in the fingertips | of the gloves... maybe. You're probably right though, the | vibrations of the aircraft would drown it all out. | emilecantin wrote: | This particular acronym is also used a lot in the marine | industry. Marine GPS, also known as "chartplotters", are mostly | called MFDs nowadays, as it's a much more descriptive of what | they've become. | brmgb wrote: | Touch panels on military boats are called MFDs too. They are | actually surprisingly good but they come with large handles | you can use to stabilize yourself while the boat is moving. | snide wrote: | I play a lot of Digital Combat Simulator, which models a lot of | these planes. At first I was interested in shooting things, then | I was interested in the flying, but in the end I learned I was | most interested in the computer systems and how these games are | mostly virtual simulations of old computers. It's fun to see what | changed over the years and between cultures. The MiGs are | completely different than their Western counterparts. How you | navigate from point to point is often completely different. It's | also interesting how durable the UX of MFDs were in cockpit | design. When I went for my GA license, it was funny to see how | many newer models of planes had moved to "glass" cockpits. It | some ways, it felt like putting wifi on your fridge. Most of the | GA planes folks fly were made in the 70s. | unoti wrote: | Agreed! If the information in this article is even slightly | interesting to you, then you owe it to yourself to spend some | 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 | computer systems. It's fun to _learn_ , and to operate systems, | and to feel that feeling of mastery as you gain confidence in | 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 | planes feels a lot like operating a big flying computer, at | least in the simulators. This is also true of things like the | Cessna G1000 glass cockpit in Flight Sim 2020. | mhh__ wrote: | > DCS FA18 cockpit | | One thing that's particularly impressive about the F/A-18 is | that the Spec available in DCS (give or take a few features) | is almost the same as the first batch from the 80s UI wise. | | In 1983, serving alongside the almost completely analog/60s | F-14, the F/A-18 had 3 pretty modern MFDs. Definitely more | advanced than most Star Wars cockpits, for example. | ak217 wrote: | I'm flabbergasted that MFDs haven't made more inroads in | automotive and computer input device applications. We even have | decent HUDs in cars now, but no MFDs. I'm convinced a good MFD | would be far superior to the typical touchscreen crap - if | Tesla had a MFD and a HUD instead of the giant TV screen, I | would have bought one by now. | mhh__ wrote: | I think it's because the MFD model is designed for trained | pilots who have to take a test to use them, i.e. I'd love | one, but I can just imagine the complaints about the | different pages and things like that. | | Also, I'd love one for home automation too. There's only so | much data you need to display or enter so the reduced latency | of a dumb screen going straight into the back of a internet | connected SBC (or even microcontroller) could be really nice | to have in the kitchen, rather than having to fiddle around | with either just a phone or what would end up being a tablet | bolted to a wall. | tra3 wrote: | I upgraded my car's stereo and it went from a knob for volume | control to two small buttons. Hate it. | | It was difficult enough to find stereo with dedicated volume | buttons. The rest of the functionality is via touch. Not a fan. | I've never driven a BWM, but I believe they have a knob beside | the shifter that allows you to go through the menus.. that feels | like a much better system. | t0mas88 wrote: | They do, and also a physical volume knob that you can find and | turn without looking at it. | | When I had a rental Renault that had everything on a | touchscreen I thought "cool, looks modern!" when I looked at it | stationary. And then totally hated it after 5 minutes of | driving because it is so much worse to use on the road than the | BMW system with actual buttons and the controller you can use | blindly. | jeromenerf wrote: | Renault cars have audio controls behind the right hand side | of the steering wheel, alongside the touchscreen. It works | fine and you keep your hands on the wheel. | visviva wrote: | > At present I am pressing the wrong part of the screen about 20% | of the time in flight due to either mis-identification, or more | commonly by my finger getting jostled around in turbulence or | under G. | | That seems... bad, but also totally unsurprising. | waiseristy wrote: | I'm surprised there isn't more hand rests used in these | applications, similar to how the Dragon capsule has those | finger "shelves" for the touch panels. Would make accurate | touch input at least slightly easier | t0mas88 wrote: | Some general aviation planes have this, I've only used one | during a short test flight in a simulator but it seemed to | work quite well. | jandrese wrote: | Yeah, this seems like a fairly easy workaround. A possible | limitation is the cramped cockpit may literally not have | enough room, your knees might hit the rests when working the | rudder. | | Maybe if it were a flip-down thing where you could rest your | hand when needed, but also bounce it out of the way when its | not needed. | cccc4all wrote: | F-35 is a slush fund for politicians and Military Industrial | Entertainment Technology sector. | | $1.5 Trillion and counting. | waiseristy wrote: | Alright, HN.
