  1. This has bothered me ever since I learned how to do radar fixes. I assumed it was a cheap mini joystick on my throttle, but it's good to hear you other users have the same complaint. Now is the time to get HB's attention!
  2. You should be able to use AG mode on the ground, I don't know what might be causing your problem. Some people boresight on the ground, but it's really intended to be done in the air. You can circle your own departure airfield and use one of the auxiliary vehicles or buildings, or find a point of interest en route to your target. You can also use Mav VIS mode instead, which doesn't use the TGP at all.
  3. The boresight is what enables the auto handoff by removing alignment errors between the TGP and Mav seeker. If you aren't boresighting successfully, you will not get a good handoff. Once you have boresighted, you will be able to slew the TGP to a target and the Mav will follow it. Then when in range, you can do the handoff. It also helps if the TGP is in white hot mode and the Mav is in narrow FOV.
  4. I always love homemade tools for this kind of stuff. The other week I made one to estimate the drag on the F-16. Did you guys know that if you make waypoints with the F10 map and load the cartridge, it populates the QFE values for all your waypoints in the kneeboard?
  5. Are you sure you're hearing TACAN? This does not sound like TACAN. TACAN plays only the Morse code of the station it is tuned to a long as the signal is received, regardless of what you happen to fly over.
  6. Is this screenshot an example that's hard to read on your display? I don't find the MFDs in your screenshot particularly hard to read on my monitor. I wonder if it has to do with local graphics or monitor settings?
  7. I'm missing something. When you air start on this dogfight server, are your TCN and ILS automatically tuned to active stations to give you the Morse code? And why are you flying over the approach beacons to land on an air start dog fight server, is that typical? I thought you were always supposed to get a new jet to start a new dogfight.
  8. All real forces except gravity are physically the same magnitude but need to be converted to spherical coordinates. I think it's more likely that DCS uses an atmosphere lookup table. The exponential model is not very accurate over large changes in altitude, and a table can be highly customized for variable weather conditions. Plus is is more computationally efficient to avoid exponentials. Centrifugal acceleration is "omega cross omega cross R", unrelated to gravity (omega is Earth rotation rate and R is aircraft position). Maybe you're thinking of a circular orbit where they happen to be equal? If DCS uses a flat Earth it's unlikely they are modeling Earth rotation. Thanks for humoring me while I nerd out a little bit. This simulation modeling stuff is my favorite part of my day job.
  9. A coordinate conversion from Cartesian to spherical would allow remorphing of the maps, but there's more to it. The equations of motion of all the moving objects (aircraft, missiles, ships, ground vehicles, projectiles) would have to be updated to include terms for Earth curvature (non-Cartesian) and Earth rotation (non-inertial), namely spherical coordinates with terms for spherical gravity, centrifugal acceleration, and Coriolis acceleration. (See page 7 of this paper)* Any aircraft or missiles with Inertial Navigation Systems would need to have their software updated to include the above Earth curvature and rotation effects. There may also be weapon targeting systems, such as electronic gun sights, that would need updates for Earth curvature and rotation as well. While on a flat Earth all sunlight strikes the ground at the same angle, on a spherical surface the sunlight direction for shadows and reflections needs to be calculated as a function of latitude and longitude. Maybe this could be ignored or simplified over the relatively small maps we have. All line of sight calculations between any two objects on a spherical Earth need to calculate whether the LOS intersects the ground. To be really good about it they should also add in atmospheric refraction, since in real life it allows you to see far beyond the true horizon. Refraction depends on the wavelength of the radiation (visual light, infrared, radar, etc) and atmospheric conditions such as density and humidity. * Alternatively, the equations of motion could remain Cartesian and inertial, but a whole bunch of additional conversion equations would be required to convert the Cartesian motion variables (position, velocity, attitude) into useful quantities relative to Earth and Earth's atmosphere. This is not hard or groundbreaking, it's all very standard stuff that's present in a lot of high fidelity simulation software. But it takes a ton of work along with checking and rechecking to get it all correct.
  10. It's possible they model an overall lighting scale that brings everything up or down to match the ability of your monitor to display the full dynamic range. Broad daylight is something like 10,000 times brighter than indoor lighting or a typical CRT screen.
  11. New threads are easy and free, and they keep the forum better organized and searchable. For your afterburner issue, consider using the throttle detent keybind. It's also more informative to look at the fuel flow rate than the RPM.
  12. Setting trigger UNSAFE (open safety bracket) is how you tell the CK37 that the point on the ground beneath the pipper is your target for certain CCRP calculations. Welcome to the Viggen, by the way! Hope you find it really satisfying and hope we cross paths on the multiplayer servers. We always need more Viggen pilots to support anti-ship and other strike missions on the big disorganized servers.
  13. Why is your MFD text green? Are you using a mod?
  14. Unfortunately I only have a single stage trigger.
  15. I used tooltips when learning the aircraft, then found I didn't need them anymore, not because I learned the Swedish but because I knew the positions of everything.
  16. Interesting. The Viggen guys are saying it's fixed. I figured it would be the same bug and fix.
  17. If you turn on cockpit tooltips it gives you English labels.
  18. But you can use the helmet mounted site to shoot off borsight with the 9x.
  19. Thanks for elaborating. I was thinking technically and you were writing systematically.
  20. It must use gyros of some kind, because an INS can't function without attitude data.
  21. That was a good write up, but I want to correct one thing. The main nav source is the inertial navigation system (INS). The TERNAV function is supplementary to correct for the inevitable INS drift.
  22. Again, the vertical line does not indicate where the TGP is pointing, is indicates the current Sensor Point of Interest (SPI). SP does not affect SPI, but as soon as you slew the TGP it is either in Area Track or INR, which both drive the SPI.
  23. That's great news. Any idea when ED will release a patch?
