OK thats cool! Never knew that IHAADS can project PNVS and TADS imagery through the cabin fuselage like F-35 DAS.

I was US Army active duty and then in Reserves, as Field Artillery officer Fire Support (FIST). I worked, indirectly through JTAC, with Apaches, on exercises. I had no combat deployments. I served from 1992-1995 on active. At the time AH-64A and A+ with post Desert Storm modernization was norm for active duty Aviation Bns. We did receive instruction at Ft.Sill Artillery School, on capabilities of Apache. We were never shown or instructed about ability of Apache crew to see through the fuselage, within gimbal limits of TADS. We knew they could operate 24/7 with very low minimums, nothing like what DCS: Apache shows. I suppose US Army PTB did not consider that capability as 'need to know' for artillery junior officers. Or perhaps it was not available at that time. I don't recall that capability disclosed in numerous documentaries on Apache from 1990's till GWOT , OEF AfPak, and PG OIF. Documentary voice over and crew interviews did discuss IHAADS, TADS, and PNVS , but see through fuselage ability was not mentioned.

I notice that PNVS overlay of IR imagery lags by a frame or two , is off by couple of pixels, and has lower frame rate update. I wonder if that is a real world limitation of the system?

I suppose that in near future complete spherical DAS imagery will be projected on to helmet visor, with cockpit controls projected as holography. Like flying disembodied. With helmet and flight suit lined with haptic pressure pads, alerting crew to threats.

Yes.  It has been discussed that the PNVS slews faster than the TADS, so you see more of that lag if you slave the TADS to the CPG helmet and start whipping your head around.

Also, getting a good boresight alignment calibration impacts the accuracy of how the PNVS is over-layed on the real world.

Also keep in mind that the PNVS/TADS turrets are physically mounted to the nose of the aircraft, which is why you may see an offset image when viewing objects at closer ranges.

It's actually a bug on the PNVS system right now. It's very noticeable when flying VR. Although the TADS is not as fast as the PNVS, it's much smoother and more comfortable to use. The PNVS in VR has a very distinct stutter when moving your head around, making it impossible to use in any meaningful way.

If its a bug, OK. It may not be a bug but emulation of real world system's limitation.

There are two things at play. There is the slew rate being limited as per the real aircraft. Which is not being discussed here.

The bug is that the actual video feed for PNVS runs at a seemingly lower frame rate than the TADS. So even moving your head incredibly slowly, will result in stuttering views.

Technicly talking, aint the ''F35 DAS like the IHADSS'' and not the other way around ?

F35 DAS is not the same as IHADSS. DAS uses a different system.

[DmitriKozlowsky]

I believe that F-35 DAS projects 360 all spherical POV onto visor allowing for more accurate depth perception. DAS uses distributed sensors, so it has no FOV limits. I imagine is like flying disembodied, which may be weird at first. F-35's helmet is unique to F-35 is the aircraft's primary flight instrument. Or so it is said. Probably the shape of things to come on all manned air systems. But thats off topic.

No the DAS is a sensor it does not project like Bobba Fett's Helmet or Wraiths Helmet. The F35 Helmet projects onto the Helmet similar to the HUD. So if you look at an aircraft outside then you would see it and a box showing its position. If it passes your view during a dogfight then it can give IFF colour to the aircrafts box. The SCORPION is totally different, it is in the same class as IHADSS which detects and translates everything 360 x 360 including being able to look through the aircraft. The SCORPION Helmet has more levels of Night Vision and essentially makes Night like a clear Day through the Helmet. There is an Infantry Version and Law Enforcement Version which can track stolen vehicles using a Tracker. So the F35 Helmet is like the HUD but the SCORPION Helmet is more like IHADSS but has more features and more levels of Night Vision. F35 Pilots will probably get the SCORPION HELMET. And they would get the best performance in all roles with it. There is a video on DAS and then you could see the difference, the difference in accuracy with a SCORPION HELMET. The SCORPION HELMET is precise with object location. It also does a wire frame of ships when you are approaching an aircraft carrier or ship in IFR then you can still see it precisely. For helicopters and Search and Rescue it is the best technology.

 

 

One point EO DAS does not look through the floor like IHADSS. It is something else that does this. What it can do is show through the floor a target or point that is being detected and tracked by its thermal image.

He's refering to the ability to see trought some part of the cockpit, not on the technical aspect of it
