The Most Advanced 5th Gen Cockpit? | F-35 Lightning

[@SkyhawkSteve]

back in the mid-80's, as a young engineer at McDonnell Douglas in the flight simulator group, I saw that they had a cockpit mocked up as the "cockpit of the future". It was a big screen, with all of the radar, nav, comm, etc., info all merged into one big display. This was when the F-18 was still new and the glass cockpit was evolving. They certainly knew where they wanted technology to go, but the display technology and processing power still needed a lot of development.

[@LRRPFco52]

@@SkyhawkSteve There were 1980s artist renderings of the future fighter Man Machine Interface as well, with an HMD and full glass panel cockpit. Loral had some cool artwork that was featured in Aviation Week & Space Technology frequently. The actual systems development was going on right under our noses with the AFTI F-16 at Edwards AFB from about 1982-forward. It was always a cool plane to see and check out whatever cockpit variation they were using at the time.

Having read about these systems, I understood how they worked but seeing them in action really convinced me of their capabilities.

[@fredsalfa]

That’s really incredible. My dad was a P51D fighter pilot in WW2. I wish he could have been here to see the latest and best fighter planes of today. I wonder what he would have thought about these planes.

[@lovetoride9646]

Fascinating. It was cool to see how the instructor, Puff, walks around in front of the cockpit and reaches inside to assist. It makes using the simulator seem so easy. It's great that the air force is so open with their systems. Even after this great insight I still have absolutely no idea how it works🤗

[@johnburpi8484]

What I’m most impressed is how automated everything is it’s truly like playing a video game. One thing I wish you could ask is how has this impacted training I would love detail video about what parts of training f35 pilots vs legacy aircraft pilots get Easier and harder what unique challenges or skills each pilot has when training in the f35 and weather the access of flight simulators like DCS or Microsoft flight simulator has any long term impacts on training future pilots when aircraft become more digital each year. Love to ask these questions

[@MilitaryAviationHistory]

I'll note them down :)

[@LRRPFco52]

It’s harder to train a 4th Gen pilot to fight in the F-22A or F-35s because they have so many different task sets and task-switching habits trained in well, whereas a new pilot is fresh with no 4th Gen habits. Managing all the information is hard though, because there is so much more of it in a 5th Gen cockpit as you can see. 4th Gen has federated displays and systems where you have to HUD-Radar-RWR-FLIR scan, whereas this is all fused in the F-35 HMD and PCD. F-35 Situational Awareness is an unfair advantage, and even former F-22 pilots who have gone F-35A say they have more SA in the -35 than the -22. The F-22 has far more SA than legacy 4.5 Gen fighters, with huge gaps in sensor performance and fusion that don’t exist on legacy birds.

[@davydatwood3158]

That was super interesting, so thank you to all involved. Two main thoughts in my head: first, the data sharing capabilities sound so much like what David Drake was describing in his novels in the 80s and 90s. Clearly everyone knew where they wanted to go, and now we're finally getting there. Second, I've been doing a lot of training for work this past fortnight, and have dealt with a wide range of instructor personalities and skill levels. "Puff" was just perfect, clear explanations, stead tone of voice, steady speed of instruction. I'm very impressed and I'm sure his students appreciate him!

It's interesting to see how the displays have changed since the pre-production days.

But it was many years ago, and I didn't see them in situ for that long.

[@FISSIONINITIATEDSUNRISE]

I'm soo acustomed to flying the f35 in microsoft flight sim that I'm mechanically itching the pre dial my nav and autopilot the second I see the interface. The only thing shown here which is lacking in MCFS is the radar, which will be aded in the next update. The speed bleedoff during that maneuver and the angle shift is pretty indentical to the MCFS plane . Also, the plane in the game is slightly less sensitive on takeoff. Those guys at indiafoxtecho really nailed the thing with the game addon. Fantastic video.

The anime itself is "ok" but I'd love to just hear you talk about the planes, and any historical accuracies or inaccuracies. From the planes themselves to the fighter group tactics, and so on. You could easily do a series of videos reacting to each episode, or just watch the series on your own time and then do a single video on the series. However you did it, I just wanna see you talk about the series and the planes in it..

[@zlm001]

This was awesome. It’s so hard to communicate the advantages of this plane without going to classified territory. So much of it is EW, and that’s some of the most secret information out there. I hear all the time about situational awareness and information management, but you can’t get an inkling of how advantageous it is without seeing how it works inside the cockpit. Lockheed Martin should do A LOT more public engagement this way. I’ve got no ground to stand on with this, but I’ve seen a couple of pilots who apparently were trained on the jet seemingly giving BS answers about the plane’s performance. One of them, it seemed to me, seemed like he was giving answers trashing the plane just to appease the two other pilot hosts who had never flown it. I guess what I’m trying to say is that there seems to be a lot of misinformation even within the fighter pilot community. Edit: comment on a decent chunk of KZbin fighter pilots being low key drama queens deleted, even though I’m sure nobody would take offense to this. 😅

That RCS screen is very peculiar. Even though it has probably have nothing to do with the reality (seems that highest visibility is in head-on aspect), I can clearly see how it could be extremely useful. Keep your threat emitters to the lowest RCS aspects until the time is right.

[@kjell-oh7ez]

As you have been in the Gripen E simulator also any comparisons?

[@MilitaryAviationHistory]

Likely in an upcoming video. The interface on the screen is quite different as both jets have distinct capabilities (example that separate screen on F-35 providing feedback on detectability). Also, I did not yet see the FLIR screen integration on Gripen (during my session).

How do they get around lack of tactile feedback when using touchscreens? It seems like it would be a huge ergonomics problem e.g. flying formation when you're eyes on lead, then you've gotta switch radio freqs/channels without taking your eyes off lead.

We worked hard AF to make it simple. In the early days pilots kept trying to get us to put buttons and switches back in the jet. Some systems did earn their way back into the jet, you can see the center console has some knobs and a few dedicated displays. For the most part though, the increase in speed and efficiency is just too good to pass up.

[@LRRPFco52]

If you look at start-up procedures, in-flight tasks, and maintenance, this cockpit smokes legacy cockpits. Legacy cockpits have a black box behind every display and panel, with wiring coming out of the back that flows into the wiring harnesses. They are a nightmare to maintain, doubled in 2-seaters. Corrosion, G forces, dust, sand, moisture, and wear and tear wreak havoc on cockpits. This is one of the several reasons why it’s so much easier to operate and maintain F-35s vs 4th Gen. Look at the MMH/FH numbers if you have doubts.

[@MrRobertX70]

@@jeffbangle4710 The screens in the F35 (actually all modern aircraft touch screens) work on a different principle than phones/tablets. While normal phone screens detect the heat from your fingertip, the F35 screens are covered with an invisible grid of laser beams and sensors. When a pilot presses on the F35 screen, his fingertip interrupts some of the laser beams and the touch location is determined based on which beams were interrupted. These screens are less likely to not register a touch and also allow pilots to operate them while wearing gloves.

The video also shows why so many other manufacturers, military and civilian, are putting so much into developing system platforms to more easily support integration of functional modules.

Rafale does not have anywhere near the sensor count or closed-loop sensor fusion that JSF has. Totally different ballgame, and the Rafale is a great system, just not really like JSF.

It’s more affordable than any other fighter on the market. Low price point for acquisition, low maintenance hours, costs the same to fly as an F-16, but one major difference is you don’t lose them at rates like legacy fighters are written off. ROI is much better with F-35s, as is pilot safety.
