"The current training program for F-35 transition pilots is 8 weeks long. The transition pilots are comprised of legacy aircraft experts such as experienced F-16 or F-22 pilots. These pilots will become F-35 instructors upon the completion of the program. Training begins with a week of military lectures, followed by 3 weeks of lectures and academic courses specific to the F-35. A pilot training aid (PTA) laptop simulator is flown by transition pilots during these early phases of the course. The last phase of the training program is a mixture of 8-10 F-35 Full Mission Simulator (FMS) sessions and 4-5 actual flights in the F-35. The PTA and the FMS are the two main simulators used in the transition curriculum.",,etc.

Das coming to next gen Tilt-roter
*please ignore the scantly clad women click bate* ... game-17509

new Army-led effort to engineer a next-generation tiltrotor aircraft for the 2030s includes the integration of a high-tech 360-degree sensor suite quite similar to the one used on the F-35 Joint Strike Fighter called a Distributed Aperture Systems, or DAS, developers explained.

“Instead of having sensors mounted to the turret, you have sensors that are mounted to the aircraft – so essentially you have sensors staring in 360-degrees around the aircraft at any given time. Those images are stitched together so it appears as one continuous image to the pilot. Both pilots can make use of the

I could see a lot of potential applications to EODAS style spherical system. Tanks, IFVs, APCs and other ground vehicles definitely. Rotary wing aircraft also and also maybe UAS/UAV/UCAVs could benefit from such sensor systems. Only problem is money and also space/volume/weight in some applications. Of course these things are getting smaller and consume less power and the computing systems to handle the image data gets smaller and more efficient.

I've thought for a while that DAS on UAS would be a good way to implement sense and avoid for integrating UAS into the NAS, assuming you could get the cost and size down enough.

This is a small sub-section relevant to the new lightweight helmet and ejection seat system - either go to SOURCE URL or this forum URL for relevant text about MB seat modifications that go head in helmet with the whole shebang:
F-35 Program Office Hopeful to Move Out on Ejection Seat Retrofit Plan This Fall
19 Sep 2016 Valerie Insinna

WASHINGTON — With just one test to go, the F-35 joint program office is confident that modifications made to the aircraft’s helmet and ejection seat will ultimately fix issues that greatly increase the risk of casualties to lightweight pilots upon being ejected from the plane....

...In an exclusive interview with Defense News, JPO officials said they expect the Air Force will be able to remove all weight restrictions following the final test of the modified escape system later this month. Preliminary data indicates that the upgraded seat and lighter helmet will have removed what the service termed “excessive” and “elevated” risk to light and mid-weight pilots, said Todd Mellon, the joint program office's executive director....

...The lightweight helmets will also begin coming off of Rockwell Collins’ production line this November,  but will be limited to six units this year, said Rich Lukasik, the JPO’s helmet mounted display lead integration engineer. Pilots below the 136-pound weight threshold will be the first to obtain the helmets. Full production of the lightweight helmet starts in 2017.

“Once we begin and get the ramp to an appropriate point, the only thing we’ll produce is the lightweight helmets,” Mellon said."

Headline misleading perhaps however there are 'improvements' also 'perhaps' on the way for HMDS III according to article.
Contractor Reports Progress on F-35’s Gen III Light Helmet
23 Sep 2016 Stew Magnuson

"Rockwell Collins, maker of the F-35 joint strike fighter’s helmet mounted display system, will begin delivering a lighter version of the system next year, company executives said in a recent interview....

...A half pound has been shaved off the helmet’s weight, which will re-adjust the center of gravity, said Joe F. Ray, the company’s marketing manager for government systems. All pilots, not just the lighter ones, will receive the new version of the Gen III helmets next year.

“Pilots of all shapes and sizes, if you will, will be able to operate the helmet,” said Brad Haselhorst, Rockwell Collin’s vice president for government systems strategy and development.

The helmet’s display system is an integral part of the F-35, but one that has suffered some development setbacks. Gen II helmets had an issue with the tracker. That has been resolved. “Now the pilots aren’t having any of the delays or inconsistencies in the visual system,” Ray said.

“Just like any system that you have, when it’s new and it’s unique, you’re going to have issues. We understand that. You just continue to plug though and now we have, we think, a pretty good product,” Ray said.

The Gen III models went into production about two years ago, Haselhorst said. Approximately 170 have been issued and 400 are on order. It has been baselined, meaning its design will remain as is for the next 2,400 or so units produced....

...Rockwell Collins will continue to look into improvements. “We want to be able, from our contribution, reduce the amount of power, make it lighter, make it more comfortable for the pilot,” Ray said.

Reducing the power consumption would lessen the amount of heat being emitted and would make the helmet more comfortable. Shaving off energy needs, no matter how small, is important. “Even in an aircraft like the F-35, you’re always concerned about power because you’re putting more capabilities on the aircraft,” Ray said.

The company could make that adjustment by using “visual organic light-emitting diodes,” an emerging technology that Haselhorst predicted will be in most consumer televisions within the next five years. “It’s light and takes less power,” he said.

Rockwell Collins is also working with prime contractor Lockheed Martin to reduce the cost of the display system as part of an overall effort to reduce the per-aircraft price tag. “Everybody is trying to get the costs down,” Haselhorst said. As the rate production rates go up, the manufacturing process will become more efficient, which should result in some savings, he added.

Meanwhile, pilots are having to change their thinking about the technology. [easy tell 'em and anyway they see for themselves how important HMDS is to the F-35] They can’t have a cavalier attitude and treat the system like their old helmets. This education begins at one of the three pilot fit facilities, where trainees are issued individually designed helmets, Ray said.

Pilots sit in a chair, where a laser takes precise measurements of their jaw structure and head. Frames come in standard sizes: small, medium, large and extra large, but the data taken from the measurement is processed and then used to whittle down the inside liner for a precise fit. The display’s apex is also adjusted.

Since everyone’s eyes are different, measurements are taken of them for the display as well.

Pilots used to throw their helmets on the ground,” [bollocks - in RAN FAA the safety equipment guys would throw YOU to the ground if they saw that] Ray said. It has to be impressed upon them “this isn’t just a helmet. You need it for protection, but this is your cockpit and you have to treat it that way. ... The aircraft doesn’t fly without it.”"

Which display? I'll guess you mean the helmet display? No point getting airborne without it however if it fails inflight then there is the PCD Panoramic Cockpit Display to get home with (or complete the mission if that important). Vice Versa an F-35 pilot said he could complete the mission with a bag over his head - so there is that.

Bright Future?

"...Dogs & Reapers Share the Deck - Green Glow
Despite the success at qualifying by day, VFA-101 pilots were unable to qualify for night operations. Software for the Generation III helmet has not been released to the fleet, but was being tested in DT III. Briggs [Thomas Briggs, the Air Vehicle Engineering Department Head of the F-35 Lightning II ITF] explained that during DT II the helmet did not function optimally: “During DT I, test pilots discovered a green glow, as if they were looking through a dirty window. The pilots could not see the lighting of the ship and also had difficulty seeing aircraft around them. In DT II we saw an improvement, but the problem was not fully solved. In normal overland night operations it was not really an issue, but in a moonless dark night at sea it was. We expect to have this problem fully solved now.”...

F-35 Helmet, Ahead of Our Time [LONG ARTICLE]
19 Nov 2016 DVIDS

"...Fabricated with its own Display Management Computer Hardware operating system the helmet enables pilots to toggle through different modes of data visualization. It also delivers a more efficient video feed than the F-35’s Gen II helmets — equipping pilots with symbology correlated inside the cockpit as well as outside the aircraft with the use of the Distributed Aperture System (DAS). Using multiple DAS cameras installed peripherally around the aircraft, the pilot is able to display various modes of imagery such as thermal, night vision, and actual and achieve an unprecedented look-through-aircraft capability. All modes are beneficial to pilots as they deliver a clear 360-degree picture during daylight and lowlight settings. Thermal images portrayed through DAS enable pilots to view heat signatures emitted by various objects. For instance, a pilot can identify a ship running a hot engine against the vast darkness of the cold ocean. Night vision can also assist in magnifying low visibility objects against areas of very little to no light.

“The helmet mounted display (HMD) allows critical flight data to be viewable anywhere I look,” added Marine Corps Major John “IKE” Dirk, a test pilot and the F-35B DT-III Officer-In-Charge (OIC) from the Pax River Integrated Test Force (ITF) assigned to Air Test & Evaluation Squadron (VX) 23 based at Naval Air Station Patuxent River, Maryland.

“In addition to the aircraft’s flight symbology, I can display tactical data and even live night vision video. The helmet helps me find friendly and enemy aircraft, locate targets on the ground, and can even point out the ship. It is fully integrated into the aircraft systems and enables a seamless transition between tactical display and the outside world,” he added.

Joint Helmet Mounted Cuing System (JHMCS) helmets worn by pilots of legacy jets such as F/A-18 Hornets, Super Hornets, and AV-8B Harriers, take a long time to install equipment enhancements while F-35 Gen III helmets are specially designed to facilitate the quick installation of equipment, thereby reducing the maintenance time required for each helmet.

Another problem with JHMCS legacy helmets is the graphics on the display visor, which block the pilot’s ability to see through an overly bright image. Engineers worked to refine this imagery on previous iterations of the Gen III helmet and now the latest helmet enables pilots to toggle through several gradients of opacity. The pilot is also able to devote less time switching through different modes and doesn’t have to physically install Night Vision Goggles before starting a night mission because the Night Vision Device (NVD) is built-in.

“Legacy systems are often limited to a fixed heads-up display or separated into several systems — targeting helmet, night vision goggles, heads up display, etc.,” Dirk said. “The F-35 helmet integrates all of these capabilities and more into one balanced and comfortable helmet, complete with active noise reduction.”

These technological advancements of the F-35 Gen III helmet will save military expenditures due to several new factors.

The use of laser scanning technology creates an exact replica of a pilot’s skull, thereby fabricating a portable styrofoam helmet liner that is a break-through above and beyond the traditional custom-designed helmet for each pilot. This styrofoam cap fits into any size helmet, enabling a pilot to take the helmet liner from squadron to squadron for use throughout his or her career, optimizing the flexibility of the pilot flight equipment inventory, eliminating risk of damage to helmets during squadron transitions, and reducing investments in large inventories of helmets.

As the pilot dons the cap and helmet, two ocular cameras situated above the helmet’s display visor are manually aligned to his or her interpupillary distance (IPD) settings for each eye to ensure the acuity of each pilot’s vision and establish the proper fit of each helmet.

“The helmet is definitely well worth it considering what it brings to the fleet, the capability it brings to the warfighter who keeps us safe, and how it equips all of the pilots,” said Smith, referring to the clear 360-degree picture of the battlespace that the helmet delivers.

This unrivaled situational awareness equips the pilot with an unparalleled ability to dominate the tactical environment. Likewise, commanders at sea, in the air or on the ground immediately receive information collected by the F-35’s sensors via data link — empowering them with an instantaneous, high-fidelity view of ongoing operations, making the F-35 a formidable force multiplier while enhancing coalition operations.

Additionally, legacy aircraft only displayed targets on screens installed inside the actual cockpit, creating a disadvantage because pilots would have to turn their heads away from their surroundings. Now, F-35 pilots can focus on their targets via the Gen III helmet display visor. This empowers them to keep track of adversaries farther than they could ever turn their heads...."

F-35 Helmet "Green glow" issue still not resolved. Problem still identified during shipboard trials in low light conditions:

F-35’s $400K Helmet Still Blinds Pilots on Night Flights

"A software fix designed to make the F-35 Joint Strike fighter’s state-of-the-art helmet easier to use for Navy and Marine Corps pilots landing on ships at night is still falling short of the mark, the program executive officer for the F-35 Joint Program Office said Monday.

One discovery made as the F-35C Navy carrier variant and F-35B Marine Corps “jump jet” variant wrapped up ship testing this year was that the symbology on the pricey helmet was still too bright and distracting for pilots landing on carriers or amphibious ships in the lowest light conditions, Air Force Lt. Gen. Christopher Bogdan told reporters.

During the final developmental test phase for the F-35C aboard the carrier George Washington in August, officials told they were testing a new software load specifically designed to address this “green glow” problem, which can make it difficult for pilots to detect outside light sources and the cues they need to land their aircraft safely.

While testers were hopeful at the time the problem was solved, Bogdan said officials are not yet satisfied.

“The symbology on the helmet, even when turned down as low as it can, is still a little too bright,” he said. “We want to turn down that symbology so that it’s not so bright that they can’t see through it to see the lights, but if you turn it down too much, then you start not being able to see the stuff you do want to see. We have an issue there, there’s no doubt.”" ... oD+Buzz%29

A future hardware change / Gen 3.x (or 4) seems likely.
