I don't forsee pilots going away anytime soon.

There will always be a need for somebody flying the plane, making the hard decisions and seeing what is at the scene.

The media always likes to claim (Death of _____)

It's non-sense.

Modern AI isn't what most people think it really is, it'll be able to categorize, sort, ID stuff better; but it'll never be a proper substitute for a human being.

The future I see is Man & Machine combining the best parts of both along with their capabilities.

Over on previous page this thread is talk about night time 'too bright HMDS symbology' on the overall scene. Anything that helps solve the BLACK NIGHT scenario is welcome - one day we may see a video from the F-35B/C cockpit or whatevers.

On another appropriate 'talkitron' thread about F-35C Nose Gear redesign there is notable impact on the HMDS vision/oxy mask during catapulting and immediately afterwards - however nose gear may be redesigned - not HMDS I gather:

First, thanks spaz. Interesting...

However, the side-by-side provides no environmental data that would help viewers judge how close an to apples-to-apples comparison the images might be. Something simple like time of day, but for starters, others like OAT, dew point and absolute humidity would help an assessment because each can have a dramatic effect on the deltas that might be present in an image.

Second, wrt the Nz oscillations during 'C' model cat shots -- iirc Super Hornet had a similar deficiency in DT. The solution was not a default to "redesign of the strut". Rather, a systems engineering approach to the problem and ultimately, a solution was used -- as will certainly be done with F-35C. The press like to default to the most severe consequence while ignoring the most likely solutions that will be tested first. The SH solution, iirc, was an adjustment to the catapult shuttle pre-load. I expect that's where they will start for this occurrence in the 'C' as well.

As far as hardware mods go, they've stated that:

Long-term actions would not begin until 2019 and would take 12 to 36 months to complete. These include RRHB geometry that would reduce compression of the nose gear strut before launch. This course of action may require ship modifications, according to the red team.

Article gives a comparison of demands on pilot using HMD Night Vision system vs traditional NVG which are, literally, a pain in the neck to use.


http://www.businessinsider.com/f35-helmet-2017-1

God's-eye view: The F-35's helmet lets pilots see the battlefield in a radically new way

US Air Force Brig. Gen. Scott Pleus, director of the F-35 integration office and former commander of the 56th Fighter Wing at Luke Air Force Base, said that tasks in the F-35 cockpit are "unbelievably simplified" due to the helmet.

"There's no focusing, changing batteries. There's no getting things on and off in the cockpit. There's one button you press on the stick and it turns on," said Pleus, who has flown both the F-16 and F-35.

"You just climb to the airplane like you would normally do. You turn on the helmet like you normally do, and all you do is turn the night-vision camera on when you're ready to have your night-vision camera, and when you're done you turn it off. That's it."

Here's how Pleus described the process of switching to night vision in a traditional flying helmet:

"You go into a very dark room with specific testing equipment and you tune and focus your night vision goggles for night flight. You then put them into a little case you step out to your airplane, you start your airplane, you take off your airplane, once you get airborne in the night sky you put the aircraft on autopilot, reach down grab the night vision goggles, clip the night vision goggles on, turn the night vision goggles on, swing them down and they hang out in front of your face.

You have about a 20 degree field of view, it's two little tubes that sit in front of my eyes. The weight is about four pounds and it sits right here like on the end of the bill of a baseball cap is probably the easiest way to think about it.

After about two hours of flying, if you could imagine, if I hung a weight off the end of a baseball cap you're going to feel the neck strain on the back of your neck because that weight is forward of your center of gravity. At that point, you're just going to deal with the pain and you're going to keep flying around like that.

Total, from the time you're in the cockpit it's about 5 minutes of preflight before you get into the airplane and then you got about a minute once you're airborne. Additionally, those night vision goggles are operated on batteries, like, no kidding, batteries. And so you have to carry an extra pack of batteries for specifically long combat missions and you'd have to change those batteries out during flight.

So you'd have to take the whole thing off, unscrew the back of it, get a new battery put the new battery in, screw them back on that takes about four minutes to do and while you're doing that you have no night vision goggle capability. You're flying completely in the dark."

Pleus also noted that the night-vision camera built into the F-35's helmet gives pilots almost double the field view of standard night-vision goggles.

OLD VIDEO from 2015 - no mention HMDS replaces a HUD + the rest as mentioned - how much chizit? The HUD?
What can a £263k/$400k F35 helmet do? BBC News
Published on Nov 23, 2015

"The government is to set out details of its five-year defence strategy on Monday. Speaking to the BBC's Andrew Marr on Sunday, Chancellor George Osborne confirmed that by 2023, the UK would have 24 F35 jets operating from its aircraft carriers. A spokesman for the Ministry of Defence said those would be the first of a total order of 138 F35s - an expensive weapon, the helmets alone for which cost over £263,000 ($400,000). Jonathan Beale tried the helmet for himself."

Navy F-35C Pilots Test New High-Tech Helmet

Sensors in the pilot’s Generation “3 HMD” have been improved with new firmware to better enable pilots to target enemies and perform missions at night, Navy developers explained.
The new display is engineered to add more image fidelity in lower ranges of brightness and low-light conditions; this allows for better targeting and carrier-landing ability in the darkest conditions when there is no moonlight, Navy officials explained.

Some good howlers in that lot: "...An empty F-35C weighs approximately 3,500 pounds...." & "...Pilots follow a yellow light on the flight deck of the ship called the Freshnel Lens to help the trajectory of the approach, called their glide slope,..." & "...Upon landing, three doors open up and allow the tail hook to fall down, Navy pilots said...." WUT?!

A new helmet intended to address shortfalls in night vision capability, among other things, was developed and delivered to the program in 2015. Developmental testing of the new helmet is mostly complete, and officials believe that issues such as latency and jitter have been addressed. Green glow, although improved, continues to add workload for the pilots when landing at sea. Officials believe that they have done as much as they can to fix the green glow problems with the hardware currently available...."

....with all of the struggle in developing the "Latest and Greatest" lightweight F-35 flight helmet; why would not the F-22 use it, even if they do not have "ALL" of the functions from the supporting avionics. LockMart must have transfer of technology for developing similar functionality without "yet again reinventing the wheel".

And for those who would insist, commonality "can" include benefits.
