Guys, regarding the quick mode of the RB15 https://forum.dcs.world/topic/356307-rb-15-quick-release-issue/#comment-5510568, would that change be OK / good enough for you?

 

 

A minor typo, "the missiles has an operational range".

Are you sure about the word "immediately" or is there a min range or min time delay before it will start locking targets? I would expect some kind of safety minimums, and maybe a warmup time for the radar.

Good day dear Viggen drivers!

Here are the manual updates that came with the DCS update October 30th, 2024:

Manual update 2024-10-18:

.) page 29: Removed double information about the airspeed index dial; added info about red/white off flag.
.) page 29: Added pressure values for all common measuring scales.
.) page 30: Reworked description for the Attitude indicator.
.) page 31: Renamed chapter "Course ring and Course index" to "Heading ring and Heading index"; this was done for didacic reasons, because a "course" is typically used to describe a direction (a line) from or to a navigation facility (like a VOR), and a "heading" is the direction where the aircraft longitudinal axis is aligned with. For this change, a lot of literature was considered. References will be adopted in the next weeks.
.) page 58: Moved last sentence between the two pictures for didactic reasons.
.) page 73: Added header "Overview" for didactic reasons.
.) page 74: Moved subchapter "Differential" to page 73 for didactic reasons.
.) page 76: Added subchapters "Pitch trim", "Roll trim" and "Yaw trim".
.) page 76: Added description for new subchapter "Roll trim".
.) page 76: Added text " and works for pitch and roll" to chapter "Trim system".
.) page 103: Added "... reference altitude is ..." in 4^th paragraph.
.) page 165: Changed sentence to "From the static pressure from the flight data unit, the barometric altitude adjusted for sea level is calculated by the computer.".
.) page 165: Added "(above transition altitude)" in last sentence of section "CK37 calculated altitude".
.) page 168: Added "Beredskapsvarning" to header "BER mode warning".
.) page 168: Changed wording of first sentence in section "BER mode warning" slightly. Thanks to Discord user Anarion!
.) page 360: Changed section "M1-M9" slightly. Thanks to Discord user Bobthe28th!

Kind regards,

Hi @TOViper

I know you recently reworked the page about the A2/B-scope in Decembre last year , however I would like to add a few suggestions to the current version:

This is from the current 18th Oct 2024 edition:

The B-scope is used when additional detail is needed. It displays a vertical extent about the range of a selected waypoint

from -6 km (near side) to +4 km (far side), and ±20° horizontally. This view takes the distance to a selected waypoint (left picture),

and places the near and far borders accordingly, but it doesn't attempt to scan the waypoint itself. The mode just scans at the same

range to the selected waypoint, no matter if this waypoint is in front or behind the aircraft.

 

A couple of things:

- we may be splitting hairs here, but the near and far limits are 6,5 and 3,5 km respectively

-I would rephrase the 2nd part of the paragraph here:

This view takes the distance to a selected waypoint (left picture), and places the near and far borders accordingly, but it doesn't attempt to scan the waypoint itself..

 

 I understand what you try to say and it is somewhat clear, but it could be worded differently and slightly more accurately . I would suggest:

The A2 / B-scope mode is used to provide additional detail of a specific area.

It displays a vertical extent about the range of a selected waypoint from -6.5km (near side) to +3.5 km (far side), and ±20° horizontally

It is important to note that this enlarged view of the area is not anchored to the actual waypoint  itself, the radar only takes the distance to the selected waypoint for reference and shows an enlarged view of the area currently ahead of the aircraft at that distance with the following borders :  -6.5 to +3.5 km distance to selected waypoint and -/+20 degrees left/right of the current aircraft heading.

Whether or not the selected waypoint itself is located within that area or not is not relevant for the radar scan orientation in A2 mode. It scans ahead of the aircraft within the above-mentioned limits , regardless of the actual selected waypoint location being to the left/right of that area or even behind the aircraft.

 

I would also definetely add  that the radar picture in A2 mode is compensated for speed and doesn't "move" with the aircraft but stays "in place"

Something like this:

The enlarged area view shown in A2 mode is automatically compensated for aircraft speed , so the radar picture does not "move along" as the aircraft moves.

In other words the radar scans and shows the same geographical area (unless you change aircraft heading) while the aircraft is flying towards that area.

This compensation for aircraft speed ceases when the aircraft approaches:

0.6 km range to the "bottom" limit of the scanned area when radar range is set to 15km

1.2  km range to the "bottom" limit of the scanned area when radar range is set to 30km

2.4 km range to the "bottom" limit of the scanned area when radar range is set to 60km

4.8 km range to the "bottom" limit of the scanned area when radar range is set to 120km

At these limits , the radar picture begins to get blanked from the bottom of the screen upwards.

However its just my suggestion and personal opinion.

I attach the relevant page from the AJ37 Del 2 Kap 1 manual:

 

Thank you for your continued hard work on improving the manual,

Kind regards,

Snappy

Ok, I'll see what I can do on that! Tahnks for posting your observations and suggestions!

[TOViper]

Guys, I need you to read through. This is the first part of my change regarding the B-scope. Another one regardin the distances will follow.

I divided the content, now spread over chapters 3 and 5:
Chapter 3 now contains only a very rough description of the B-scope (changes on page 97), and chapter 5 now hosts a detailed description (new on page 266).

This chapter is not easy to change, thus I am asking you for your opinions.

Just a comment: It seems to me that if there is going to be a version number on the manual, it should be updated with each revision rather than staying fixed at RC 2.1.

Appreciate the constant improvements, though!

[TOViper]

It has. The current version is 2.1.2410, as wished by many. A newer version is work in progress right now.

You can download the latest revision RC2.1.₂₄₁₁ using the link in the first post of this thread.

Manual revision 2024-11-12:

.) page 56: Added header "Engine data" for the data table
.) page 82: Added headers "Main landing gear", "Nose landing gear", "Limits"
.) page 82: Added text about the maximum allowable descent rate to the chapter "Limits"
.) page 184: Added didactic reference to chapters "Vind / RUTA / MÅL Overview" and "Reconnaissance"
.) page 192: Moved picture to page 191 for didactic reasons
.) page 215: Moved chapter "Canopy Jettison" to page 214 for didactic reasons
.) page 215: Reworked chapter "Ejection seat" slightly
.) page 215: Added pictures for Ejection handles and the Seat height switch
.) page 216: Reworked chapter "Oxygen" slightly
.) page 251: Removed picture (already shown in chapter 03 & to keep layout of chapter 05 consistent - no pictures)
.) page 252: Restructured chapter "AKT POS" for didactic reasons
.) page 254: Restructered chapter "Vind / RUTA / MÅL Overview" for didactic reasons
.) page 256 & 257: Restructered chapter "TID" for didactic reasons
.) page 258: Restructered chapter "TAKT" for didactic reasons
.) page 260: Moved text about Normal mode to page 259 for didactic reasons
.) page 376: Removed "I." from the header
.) page 376: Removed "II." from the header
.) page 382: Added new chapter "Miscellaneus", currently covering the special options tab and details about the two currently existing options.
.) all pages: Exchanged "Course" with "Heading" whenever applicable (following the change for page 31 that came with update 2024-10-18; note: "Course correction knob" is being kept)

Preview: The next revision will take care about the B-scope of the radar, some clarification about the target fix function, and some other small issues. Since this is a bit more difficult step than just tiny corrections & bug fixes, it might take a little more time as usual.

Kind regards,
TOViper

Just received message from Myse, which I want to share with all mindful readers of the Viggen manual.
It will be corrected with the next manual revision, but I wanted to let you all know in advance.

Would it be possible to add "weapon restriction" of which some combinations of loadout would be invalid?

Just asking, why would a restriction make a combination invalid?
If one weapon is missing, the other one is still there to be used?
Or didn't I understand what you want to say?

I understand the appeal, but cant help to wonder how many users would go into the cost of printing and binding a book of almost 400 color pages. On my case, I will stick to reading the PDF version on my iPad.

I would. But I'm not normal. I'm a documentation super-geek. Double-sided printouts and it's all good. TOViper's outstanding work deserves the best, a hard copy printout!

An iPad of that size seems perfect! I have an 11" iPad and it's too smal for comfort reading a PDF. How do you mirror the iPad to you computer, Airplay or something? EDIT: Nevermind, side-by-side window screenshot obviously! Silly me

Agree, this size screen is perfect for reading  and this is an early 10-year old 1st generation iPad Pro, but it still works perfect for this duty.

On my PC I store my DCS documentation on a Cloud Drive, and on the iPad I employ the https://www.goodreader.com/ software, to get the manual from it.
