Hey Everyone!

Time to start shipping what we've been working on this summer; starting this patch with a large upgrade to the DCS: AJS-37 Viggen! From here, we're setting our sights on launching the AI Intruder and Early -A in the next patch.

This large Viggen update overhauls and enhances many core and fundamental systems. The biggest highlight is the new electrical system, bringing a host of new warnings and failures, circuit-breaker functionality, instrument fault indications, improved RAT and AC/DC failure modelling, and more. We’ve also fixed the issue preventing RB-24 and RB-74 missile lock ons — our sincere apologies for the inconvenience.

Additional improvements include an updated RWR and database, restored KB automatic mode, major fixes to the RUTA display, and refinements to instruments, cartridge and WP management and more. In all, this update delivers a wide range of fixes and quality-of-life enhancements.

Please see the full Viggen changelog below and we can't wait to hear your feedback. We hope you enjoy! Stay tuned for the launch of the Intruder and early Kitty as we wrap up the summer's work.

Your Heatblur Team



DCS: AJS-37 Viggen by Heatblur Simulations

  • NEW and overhauled Electric System
  • NEW warnings and failures
    • Electrics
    • Hydraulics
    • Autopilot
    • AFK
    • Reverser
  • Changes to the RWR
    • Updated database to be closer to the F-4’s
    • Fixed radar carrier freq. not being set (ELINT file now has the emitter band set correctly)
    • KB’s automatic mode works again.
    • Added full fidelity MiG-29 to RWR library
  • Added logic for the breakers
  • ADI aligns to magnetic heading (+ deviation correction set) on the ground and if the fast erect button is pressed. Calibrated to true heading on rotation (based on stored runway heading)
  • Added warning flag logic to air speed indicator and altimeter (LDOK)
  • Cartridge loading now requires being on the ground and in BER
  • Airbrake will slowly close from the airflow if hydraulic pressure is lost in Syst. 1
  • RAT failure when extended happens at much lower air speeds (>700 km/h)
  • Added AC-DC rectifier failure
  • Implemented a fix for “rough search” on reciprocal runways
  • Fixed the “BANA line” hiding
  • Fixed RR/ANF “cross” on CI stuck on screen
  • Temperature measuring logic has been improved
  • Flood lighting is now on during cold starts
  • Implemented a random start position for the ADI
  • Fixed kneeboard WP names
  • Backup heading now shows raw magnetic heading, without declination correction
  • Fixed HUD/ADI commands being stuck to U point
  • Added logic to unselect U point (Safety unsafe or ANF selected)
  • U point can now be reselected after having been overflown
  • Timeline and compass now shows in LowNav mode when <40s from U WP
  • Fixed RB-24 and RB-74 (Sidewinders) not locking anymore
  • Setting rb15 ToT now only requires pressing BX button (without needing to press 8 as well)
  • Updated rb15 ToT calculations
  • FÄLLDLAST now illuminates on light test
  • Added variable indicator light brightness
  • Added instrument backup lighting
  • Added instrument fault indications
    • Distance
    • Fuel
    • Speed
    • Altimeter
    • ADI
    • Pitch trim
  • Corrected RUTA display
    • Circle now shows R point location – it moves between them on “WP change” when drawn
    • Line now alternates pointing toward previous and next RUTA WP
    • Only draws R points that are “in order” (ie. with R1,2,3,4 all 4 are shown, but with R1,2,3,5 only 1 to 3 are)
  • Changes to “Destination presentation” when a R WP is selected
  • AoA indicator shows aircraft pitch on the ground
  • Changed yaw Trim switch hint from “Emergency Yaw Trim” to “Yaw Trim”
  • Updated the manual
  • Like 6
  • Thanks 6

Love that you guys are still working on this, its a wonderful module. Thank you!

Also a user request (prayer?) - your other modules come with some bundled campaigns and mini-campaigns. Here's begging for a Heatblur Kola map campaign for the beloved Viggen!

It is "just" the known issue. As explained in the threads, the exact way how the bug surfaces on your end changes with each update (for technical reasons - its called "Undefined Behavior").

1. If I manually enter the coordinates into the inertial system, there won't be a problem.

2. If you insert the cartridge in NAV mode, then close the Kneeboard, switch the mode to BER and dial 9099, everything works. (50%)
