** DCS: AJS-37 WIP Pre-Release Manual Released! **

[AdurianJ]

I dont know if I didnt notice in the manual, the manual has that feature not documented yet or the feature itself is still WIP.

 

 

The timing between ejections on the BK90 should be variable. Probably it would be set in a similar way as the RBS15 seeker is programmed.

 

The Viggen can't use the full functionality of the DWS-39 probably due to a lack of computer power and supporting avionics.

MIL-STD-1553. Either it supports it, which it obviously does, or it doesnt.

It can speak to the RBS15, which uses the same bus, quite elaborately. Setting a variable for ejection timing doesnt require an anymore computing power nor more bandwith then updating the weapons self coordinates, target coordinates or traveling altitude.

 

I have programmed "computers" less powerfull then the upgraded Viggen ones. There is really no performance problem to implement such a feature. :D

 

For the avionics, all it needs is the data panel to write a few flags to some register on the BK90s. Nothing it doesnt do with the RBS15.

 

Could possibly also be set on the ground only. But given that the MIL-STD-1553 is used to set other values anyways.

:)

 

I mean I dont _know_ it, but knowing what is used for on the Viggen, from a technical standpoint it doesnt require a different functionality from the computer then what is already used by BK90 and RBS15.

 

I dunno maybe there is another reason I dont know about, but thats why I am asking. :D

Well I wouldn't be so sure, MIL STD are NATO Standard, and Sweden is not part of NATO. For Gripen they use the bus, but I'm not that sure for the case of the Viggen...

They would have to since the weapons they use in the AJS upgrade uses said standard. The AJS upgrade was done specifically for it to be able to carry weapons designed for the Gripen system.

100% sure that it is MIL-STD-1553. People who worked on that confirmed that and iirc its some military version of a z80 processor which interfaces the MIL-STD1553 to the "old" system.

 

 

 

Its somewhere in the 90000000 pages Viggen thread before it had its own subforum.

 

 

EDIT: OCR'd manuals to the rescue:

@Leatherneck : Here are more errors to fix (and some questions). BTW, I can't wait to fly the beast!:joystick:

 

 

161 : "The first press of the button will clear the own-position fix", OK but which one? The one that was just entered? The sentence should be more precise.

 

171 : "The fuel required is the amount of fuel..." : the required fuel?

176 : "How this is done is described below is discussed below" : repetition

176 : "with such a rate that is reaches" : it

176 : "If the LOWNAV HUD mode is used the course..." : missing coma

176 : "the course scale and timeline with markers remains visible": remain

176 : "by pressing the waypoint button for the target in mode AKT POS. Switching to master mode ANF or setting trigger to UNSAFE.": I don't get it. Maybe the stop should be a coma, instead?

178 : "Clearing the data indicator, for example if a wrong number is entered is done" : missing coma

180 : "After this input the next set of coordinates." : missing coma

186 : Figure 144 shows that we can only use 4th and 5th digits to enter the distance. If that is true, there should be some explanation about the useless 6th digit.

187 : "A failed transfer is indicated by the flashing stops."

188 : "the fuel indicator indicated" : indicates

187 : "the necessary fuel required fo the mission" : repetition? + required fuel

I don't know what others think, but I'm finding the typeface (font) used in the manual quite a strain to read for long.

 

Not had this issue with any of the other manuals - compared to the MiG-21 manual, even, which is very clear and easy going on the eyes.

Question about a contingency, parralel runways...

 

from the manual:

 

How do we know a runway 27R from 27L, or even C? How is this solved for McCarran on Nevada?

Serif'd fonts like in the pre-release manual aren't everyone's cup of tea, and I'm among those who much prefer fonts without serifs. I hope the AJS manual will use the same font as the Mig's manual. :)

171 : "The fuel required is the amount of fuel..." : the required fuel?

187 : "the necessary fuel required fo the mission" : repetition? + required fuel

 

It sounds backwards, but "fuel required" is often used in aviation terms. I guess because it's stated under the fuel paragraph in loadsheets and flightplans.

 

Fuel:

Enroute___

Diversion___

Reserve___

Extra___

=======

Required.

[Flappie]

I agree. The most important to me is to have the same expression used all along the section.

 

Fuel calculations

 

The required fuel is continuously calculated and displayed as the amount of fuel required from the aircraft’s current position to the next destination and the remaining route to the primary landing site (L1) and the amount of fuel required for a landing.

 

The fuel required is the amount of fuel the aircraft requires currently to fulfil the planned flight as programmed into the computer. The computer accounts for the increased drag due to weapons and planned flight path and profile, taking into consideration the variables of ingress speeds and wind.

I asked to keep to 'required fuel' because it's the first expression used in the section. To me, it's important to keep the same expression to facilitate the learning.

 

But Leatherneck team could also stick to 'fuel required' all along that section.

Please, it is possible to free the PDF in the section "copy of content". Thank.

Hola ruso, yo no comprendo tu mensaje. Quieres descargar la documentacion del Viggen?

 

Puedes lo descargar aqui (flecha arriba a la derecha).

[Skulleader]

Hello guys,

I would like to know if it's possible to have the last version of the manual ?

The manual available to download here is good but a new version will be better, no ?

Or we must wait friday for the official release ?

 

Thanks again, Skull.

only 4 days left, it's ok to wait ;)

Thank you Flappie. But what I want is to be able to do a short-cut (edit) of the manual to translate it. Right now with the version that I have this possibility is not allowed. A greeting.

[Flappie]

Ah OK! My bad.

http://www.loneflyer.com/saab-boz-100/

 

The manual and current WIP releases show 36 flares and 72chaff iirc, the only info out there I can find about the BOZ100 is 540 55m chaff cartridges amounting to 80kg of chaff and 28 flares.

 

Iirc that is also corresponding with numbers in the pre subforum aera viggen thread.

 

I know that there are slight variances in the boz100 series. But A its same perdiod, the BOZ100 is just 11kgs heavier then the KB pod weight listed in the manual. So even if the KB we have only loads 70kg of chaff, that would be nearly 1kg per chaff cartridge atm. Which is pretty ridicoulous thought. :D

 

So is that aspect still considered WIP or do we have better data basis which supports the CM composition atm ? :)

[Flappie]

@Leatherneck: Time for some more fixes :

 

188 : "A similar indication will be displayed as for the B1." : remove the? or add waypoint?

188 : "Output of navigation data" : different font used

188 : "Output AKT POS" : different font used

188 : "in mode AKT POS the aircraft current position" : missing coma

190 : "This is done by in mode" : remove by?

193 : "With the data selector in TID the current time" : missing coma

194 : "Before take-off the remaining time..." : missing coma

194 : "...the remaining time to take-off time is displayed in the same manner." : repetition?

194 : "This mode in indicated by the number seven (7) in shown in the first digit on the data indicator." : the sentence is wrong

197 : "can be pressed at any one time" : remove one?

197 : "The letter buttons (A/G, B, C/F, C2, D/E) on the second row are used to selecting the different channels" : select?

197 : "Every sixth position of the selector knob" : positions

198 : "The top row of button" : buttons

198 : "The frequency selector requires the" : unfinished sentence

199 : "The backup radio FR 24 is and VHF AM radio" : remove and?

199 : "It has 3 fixed channels ( E, F, and G) and a fixed channel (H) for emergency channel" and a bit further "E, F, G: Preset emergency channels using the FR24 backup radio." : If all four channels are emergency channels, the first sentence might need a reformulation.

201 : "Therefore, the pilot does not need to operate the battery and can be considered to always switched on." : which can be considered always switched on

201 : "Speeds over 700 km/h may lead to damage of the RAT and at speeds below 290 km/h no voltage is generated." : missing comas?

201 : "Extension of the RAT occurs automatically when the nose wheel is depressed and is retracted" : missing coma

205 : "Failure cases." : text is missing style

205 : "Indication: HYDR TR 1 lit and Master Caution" : ... is on?

210 : "Small" : mixed text styles

214 : "opens and closes to oxygen flow to the pilot’s mask. " : the?

220 : "This requires to ships to be closer" : remove to?

225 : "However, in Swedish Air Force service only flew" : missing coma

231 : "Before engine star- up" : start

231 : "Press and check that all indicator lights on the warning panel." : remove that?

231 : "Without Ground power ELFEL, RHM FEL and CK will be lit." : missing coma before ELFEL

232 : "LD Sets altitude" : missing dot

232 : "Set correct IFF setting." : unuseful sentence?

 

 

 

I also have somes questions :

 

194 : "Calculated flight time to target is displayed if no waypoint button is pressed and no Time on Target is set." : What is designated as the target when no waypoint button is pressed? The next entered target waypoint?

 

221 : "The seeker has a range of about 8 km and an angle of ±28°" : both vertical and horizontal angle of ±28°?

 

224 : "The AGM-65 “Maverick” is an electro-optical television guided, stand-off missile designed for engaging armour, fixed units and fortified targets. " : Isn't this version of the Maverick capable of hitting mobile targets as well?

Thanks Flappie-- we're reading all of your input! Just too busy to reply properly these days

I bet you are! ;)

[Enduro14]

Cobra i apologize if its already been answered but today with the launch is the Viggen coming with a updated manual compared to what we have now? Just doing logistics for all my ipad and stuff...

[drPhibes]

No. There is no manual included in today's update (unless they hid it really well; it's not in either of the two new AJS37 folders).

[Hyperion35]

No. There is no manual included in today's update (unless they hid it really well; it's not in either of the two new AJS37 folders).

 

Yeah, normally the manuals are in Mods\Aircraft\<module name>\Doc (for example, Mods\Aircraft\Mig-21bis\Doc has the Fishbed manuals), but after downloading and installing the Viggen module, I see Mods\Aircraft\AJS37 but there is no folder Mods\Aircraft\AJS37\Doc inside it.

 

I was planning on transferring the manual from my computer to my tablet for reference while flying, but it sounds like the manual in this thread is all that's currently available.
