- Skip to 30:00 to get to completely new material. A bit of recap at the beginning, with some amplifying information about the left seat runup.
Finishing the right seat runup (right-seat checklist complete).
Detailed discussion about the NAV ALIGN process, FADEC SYSTEM check, how the RADALT (radar altimeter) works, and getting the aircraft to 100%, ready to fly (but not complete on the left-seat tasks).
Super nerdy.
The discussion of the NAV ALIGN process got a little convoluted around the Initial Position key. Stick with it and ignore the confusing blather and eventually I get there. - Auta a dopravní prostředky
We really appreciate the amount of time and effort to bring us "as close to reality as possible" Kiowa. Your derailing is even more appreciated, because we love to know everything. I hope the multi-crew will be available ASAP, because I want to see You and Casmo doing Your magic. Thanks a lot for these videos. And I mean all the videos on Your channel. Great stuff!
Thanks for your comment! I'm kinda amazed people are still watching this 9 months later!
There'll be more coming, rest assured.
Probly some collaborative stuff with Casmo too.
Cheers!
@@Barundus Maybe it looks strange to You, but even the boring stuff for You, is exciting stuff for us. :-) Cant wait for more videos. And even Im not from US, I thank You and others for Your service. Take care!
25:52 Don't worry about derailing!! You stated pretty clearly at the beginning of this introduction video series, that it is NOT about doing a quick startup, but about taking a detailed look at the process and the respective systems and that's exactly why I'm here (and probably others as well)! So don't worry about getting off track. I really enjoy that kind of additional information!
I tell people that I fly a military grade flight simulator and they think, oh, you can shoot missiles and drop bombs! This video (the first I've seen) will say to them, uh, it's complicated...
Barundus, this video is unbelieveably intense. The aircraft is just as intense. My god, this is going to be.... I'm beyond words. I just spent almost an hour and a half listening to ever single word you said.
Hey Barundus, First off, thank you for your service! I served in the
1/10 cav back in the early 80's when we had the 58C and AH-1S. What a
difference the 58D is to the C. Thank so much for sharing your knowledge
and creating these videos. Every one of them is outstanding and will be
a huge help for the community!
Awesome! Buffalo Soldiers!
I love this kind of deep dive nerd stuff.
To whit, a couple bits about GPS.
Military GPS receivers can be slightly more accurate than civilian ones, this is because mil receivers can access the encrypted P(Y) code. In practical terms, a receiver using the P code can get down to about 1m accuracy without external aids. A receiver with only the standard C/A code can only get down to about 3-5M accuracy without external aids. In practice, all receivers use other sensors to improve that accuracy, and that's why your phone will typically have ~1m accuracy. I don't know the actual numbers for mil GPS/INS systems, but we've all seen precision weapons go through a specific window based on GPS guidance, so it's pretty damn good.
Since Barundus mentioned that they didn't use the encrypted signal, I'm guessing they simply didn't need the P code's accuracy. This isn't that surprising, since the Kiowa didn't employ any precision weapons, and only used the GPS/INS for navigation.
Starting with block III in 2018, the satellites no longer carry the equipment to do SA. This means that as the block II sats get turned off, SA will permanently go away. The block III sats also add new civilian signals that will give unaided accuracy around 1m. Meanwhile, the military will get a new M code that will further improve their accuracy, and improve jamming/spoofing resistance.
This last part is speculation. If there were a war with a peer adversary once the constellation has moved to block III, gps would be denied to the enemy based on jamming rather than SA.
Good stuff. Welcome fellow nerd.
42:15 Fun fact, the MH-53 flew lead for the Apache's during the initial attack of Desert Storm. The 53's tossed chem lights out the back of the ramp at specific locations so the Apache's could do this very procedure.
One more awesome vid. Love the level of nerdines and knowlage. Cant wait for more vids and be able to get my hands on it!
Wow Barundus, another great video on the KW with all your expertise :D
Don't worry about going off track, I think most of us here love that you are treading in so much detail :P
Many thanks for making these videos. I will be making a voice-attack profile for the checklists to help in VR, probably using male/female voices to separate the left/right seats. I find that the action of making the profiles helps with actually remembering them so hopefully I will hit the ground running when the release date arrives. Keep the videos coming, much appreciated.
please do that sounds awesome
Great little bonus "brief history of GPS" tucked in there about 52:00. Thanks for that!
You bet! I don't claim 100% accuracy on all the details; but it's close.
Yeah! I'm not an expert but your broad strokes are much appreciated. If you want a real head-trip, check out how satellite navigation helped prove some of Einstein's theories practically. It's wild! www.pri.org/stories/2015-06-08/next-time-your-gps-gets-you-somewhere-time-thank-albert-einstein
So much knowledge expressed. Impressive! Outside Kiowa related systems description, I am getting good general knowledge on the nitty gritty of some of these avaition systems that I did know earlier. Looking forward to the Kiowa in dcs. Great video.
Plan on sitting down and watching these again while taking notes, will be good for getting a start on learning the module.
so awesome! can't wait to fly it!
can't wait to fly this one ! :) Very interesting videos. Thanks a lot.
These videos are great, keep them up.
I don't know how you resisted saying "The kiowa knows where it is because it knows where it isn't" after talking about the nav align for so long haha
OMG yes. Missile guidance 101.
Great Vids Barundus, Hats of to You and Casmo, I was on the other side I was a Ground Pounder INF/JFO. Great intro to one of the best platforms ever made. Miss them buzzing around. As a Follow up to Pt4 you should do a run up, and taxi out/and different style of your take offs. Like Coming out of COP, Small FOB,Jump Farp etc.versus Jbad,Bag,Khand Etc. Would be cool for some of the Rotor heads in DCS to see.
Cant Say it Scouts XXX cause i was Blue Cord and you know we dont do that LOL. But Awsome stuff. Later on down the road a smal CCA vid would be cool.
thanks for the comment!
incredible these are still garnering the occasional view.
I absolutely will do more vids, so watch for those.
I know anything 19D is like a poopy diaper to you 11Bang-Bangs, lol.
Check Casmo's channel; he and I did a very rough attempt at a short scout mission in the early days of his channel.
Great Job. Great video. Great chopper. I already love it. Come on release it already!
Another excellent video. You must have been an awesome instructor pilot
Well if you ask me...😁
Edited, reworded, erased, and .... well, just wow.
Yihaa Kiowa deepdive continues :P
Good afternoon sir! all your vids are awesome and very helpfull! Would you upload SHUTDOWN procedure too?
Amping up the capabilities of the datalink to what they could theoretically do would be absolutely sick. Lasing a target already is still great but being able to generate coordinates for JDAM strikes across multiple targets would be insane! Could be an absolute nightmare to implement though.
I'm hoping that it's possible to get everything warmed up properly reasonably quickly with some practice. Mainly for multiplayer purposes where I might need to get back in fast if something's gone really wrong and/or I've done something stupid.
I did really enjoy this deep dive into the cockpit and systems though. It's really interesting to see insight from someone who flew it operationally.
It can already generate the target location/grid. Passing it digitally to another platform is the sticky point. We actually didn't do that much IRL, although the system was there. Most targeting info was passed voice.
ETA on part 5?
Anyone else notice that the pressure altitude displayed on the MFD pages differ by 10 feet on the left and right sides? Left seat showing 40ft, right side showing 50ft. Is that a bug, or am I missing something?
Good catch. Though I state in the vid several times the left and right side of the cockpit are not correctly synchronized in-game yet.
pleeaaaaaaase take my money
I don't care WHAT I have to pay for this!
Not a question about Kiowa persay but more an Army doctrine question. I've always felt like you lose something special from the peaking ability of the Kiowa going to the Apache. Being able to look over something without necessarily exposing yourself. Do you get some of that capability with the Longbow? Of course it’s not to the same degree as say EO/FLIR.
Longbow has the Fire-Control Radar mounted above the mast. The TADS and PNVS are mounted on the nose.
The Mast-Mounted Sight definitely allowed the ability to remain masked and expose only the optics in a near-peer, slow-moving and hovering situation.
It becomes less useful when you're at speed. The control and motors weren't designed to cope with rapid movements in the "yanking and banking" type of flying performed in the counter-insurgency conflict, nor is it that useful when looking for something nearly underneath you.
So, depends on the application.
as AH-64D shows up with existing A-10C II and F-16C modules, and if ED would update CA module with Copperhead round for SPH M-109 Paladin... it's a time to close the loop and bring the OH-58D from the fridge, full integration man.. it would be awesome.. do you think so ??
{ P.S: you left nothing to say in your 4Pts vids👍😃 except Alignment demonstration, especially with GRID NORTH in case of INU Heading Failure }
if you care to would you expand a bit on what you meant when you mentioned friction between the services re digital info sharing ? thanks !
Basically it's divergence and incompatibility between the various systems installed on the aircraft.
While there is generally an "idea" that information sharing is enabled across platforms, in many cases the reality is that the acquisitions path and budget process between services often don't end up as originally envisioned. So when aircraft and systems are modernized, often times incompatibility develops. Or; there isn't any requirement in the first place.
Many of the digital systems within the Army itself may have proprietary technology that is exclusive to one particular system, i.e., the artillery digital fires net doesn't talk to anything else. The problem is amplified when you have to go cross-service.
Workarounds are to have "gateway" systems, intended to translate one language of digits into another language of digits, but there is always friction.
odd question but how do you decide where you put the aiming dot on the windshield?
So I just came across this after watching the BlackSharkDen video where they interview Barundus and start talking about stuff out of the real life army manuals.
From TC 1-248 Aircrew Training Manual OH-58D (April 2007), Pg 4-117: Aerial ballistic reference mark (ABRM) (windscreen mark) Engagement:
(1) Prior to flight:
Pilot/Co-pilot measures from the bottom seam of the windscreen (where the riveted
metal strip meets the windscreen) and marks a point 24 inches up with a grease pencil.
Then measure from the center seam of the windscreen outward 12 inches. This is the
center point of the ABRM. Mark the point and make parallel 3/8ths inch wide by 3 inch
long horizontal and vertical lines. It should look like the outline of a plus sign.
Whether or not this is how it was actually done I couldn't say. Grease pencil was the method I've seen on the UH-1N in the USMC as well (I was a mech, not air crew).
Would you also set the Hi and Lo bug during the radar altimeter step?
You could, certainly. Personally, I never bothered with it, as we routinely bounced between altitudes so much it would just be an annoyance.
43:40 What if you actually start below sea level? Let's say you're operating out of Israel for some reason (e.g. training excersise) and startup from a forward location near the dead sea. Would a proper alignment not be possible in that case? Could you just trick the system by dialing in an altitude above sea level for the alignment and then dial in the correct altitude below sea level after the alignment is done?
I know it's a pretty unlikely situation, but it just serves as a theoretical example as I'm curious about the technical implications.
Yep, you'd have to set the altimeter to read above sea level pressure until the NAV Align is complete
First of all, thank you!
Some parts I noted:
Surprised to hear that there's so much avionics configuration needed, I expected most of that to be in the data cartridge.
On the satcom CB: I agree that it's possibly too much to integrate the system, but it would be cool to just have the CB to go along with the checklist.
Nav Align below sea level: You never were in the Netherlands with the KW, right? :D
Was fast align possible in a quick deployment scenario out of a C130? Prepare the Datacard, brief the C130 crew where to stop after landing, unload the KW and do that fast align?
A lot of it is on the mission card; however certain things can't be imported/configured directly from the card.
A proficient crew can get going within five minutes.
I agree with that. Make the CBs clickable but not necessarily functional
1:11:00 I thougth the angle of the rotor disk/swash plate is 90° offset from the direction of cyclic input, because of how spinning objects work? Or is that something separate from what is shown here?
Half correct. Gyroscopic precession causes the movement of the rotor to be 90 deg from the direction of input. Consequently you build the swashplate to translate the input automatically. In simplified terms; The force applied through the pitch change links is 90 deg from the direction you want to go. But the control movements are set up to "make sense".
This is called cyclic rigging. If we didn't build it that way, all control movements would be 90 deg from the direction you want to go, which is really hard.
@@Barundus So this is a problem of mapping input to rotor pitch angle? I always understood it as the pitch angle change has to be 90° off where you want to go, and that that's the reason the cyclic is rigged differently.
I misunderstood it as a problem of the LIFT being changed 90°, which would mean forward as highest lift and aft as lowest lift in the actual, physical rotor blade to command a left or right (depending on CW or CCW motion); consequently, the rotor plane moving forward or backward when commanding left or right cyclic.
But you say, in actuality for you to go for example to the left, the pitch (and with it the lift of the blades) should be highest on the right side of the helicopter and lowest on the left side? Again, I thought that the lift would have to be shifted, and consequently, input itself.
Instead, in reality, you'll have to 'command' the highest pitch at the front of the helicopter (assuming a CW spinning rotor) so that the highest pitch 'arrives' at the right side? And the vectors work normally like in a straight flying object, tip the right side up with more lift, dip the left side down with less lift, off you go to the left?
That means that the rotor plane is still highest on the right side (highest lift) and lowest on the left side (lowest lift).
Helicopters are really complicated, and some things are difficult to wrap the head around - spinning things are really counter intuitive.
@@GeFlixes You want to move forward. Push forward on the cyclic. PC link 90 deg out of phase moves. Helicopter moves forward.
czcams.com/video/eTjGTxSevHE/video.html
@@Barundus Thanks. So it's the lift itself that's 90° out of phase.
--Shouldn't the rotation plane/the position of the rotor blade tips not be 90° out of sync with the inputs as well? So moving left/right on cyclic moving the blades on the front of pillot closer/farther away from the ground, as they rise and fall with added lift? That's what got me stumped in the first place.--
Nevermind, I think I got it.
Will this aircraft be able to designate for fixed wing buddies?
Simply put: yes.
41:53 DCS can simulate GPS restricted environments, where GPS is not available, so I would be quite happy if INS drift and updates would be simulated for the KW eventually. It's not a priority feature of course, but would be nice to have eventually.
More than 5 hours of kiowa video and still any flying.....when did you take off ? 😉
Think of this as ground school...
Is this still under development or has it died a death?
2020 was tough. PC is still developing after some setbacks.
@@Barundus Ok thank you for your reply, I won't ask anymore, but good to see it's still in the pipeline
Stop flipping teasing me..........
