  1. You could've left your trim in DISC during the start up. That would explain both issues.
  2. Iirc for a repair you have to completely shutdown the aircraft. After that you need to do a full IRS realignment (the 8 minute one). Don't forget to enter the lat as well as the long. Default values are fine.
  3. Congratulations to me.... Woke up my family laughing...
  4. @IR.Clutch How does the INS error show? What do you intend to demonstrate with the red arrow in your description?
  5. No, works fine for me. But the JTAC supplies me with 8 digit MGRS with an 100k square identifier. It omits the gridzone designator though. Ie Nevada is 11S (which never gets mentioned) NB 1234 5678. You enter everything as is. Don't bother adding the extra zeros it accepts 8 digits, it's not that ghetto. What sometimes happens is that the grid leads with a easting zero. DCS omits that zero in the teadback and you get a 7 digit grid. That's the only time I will add zero's in the while entering MGRS coordinates.
  6. That could be very well be but in that case it should also work with 2x receivers imo, just need extra time to compensate.
  7. I don't consider BN's reply a real answer. He only stated documents reference they need 3x emitters. I asked for a reason why. Of course it's possible he can't give a reason, which is fine. At least three receivers is neither fish nor fowl. A true TDOA solution requires 4x receivers (=3x TDOA). If a solution only requires 3x receivers, my bet is the system uses a Kalman filter to get a fused location using ,3x receiver TDOA ( a curve) and multiple triangulation ellipses (the location is where the curve touches the ellipse or DTED as suggested by @toilet2000). But then this system would also work with 2x receivers (the location is where the hyperboloid touches the ellipse, if there is overlap there is a significant reduction of the area where the true location is at). The beauty of a full TDOA location it's that it is near instant high accuracy. Any location fusion with less than 4x receivers just requires (a lot of?) more time to get proper measurements and have the Kalman filter come up with a precise location. or ED interpreted the 3x TDOA as 3x receivers.
  8. The solution provided does not answer my question and is incorrect. TL;DR There are multiple variations on solving emitter locations with multilateration. In this case KlarSnow conflates 3d true-range multilateration, in the text and 2d TDOA/ pseudo-range multilateration with the visual example (both 3 receivers). But the problem in localizing a hostile emitter in DCS is a 3d TDOA (not a true-range 3d or a pseudo-range 2d) problem which according to the formula for pseudo-range multilateration, m≥d+1 (m=receivers, d=dimensions) requires at least (3+1=) 4 receivers. Hence my question; how does ED solve the 3d TDOA problem with 3 HTS equipped Vipers when technically 4 receivers are required? Now for my lengthy/nerdy explanation. Multilateration is difficult subject. To begin there are two distinct problem sets. Multilateration with known ranges, true-range multilateration, with unknown or biased ranges, known as pseudo-range multilateration. True-range multilateration can be done with radars for example. With just range 2 emitters can locate a target in a 2d situation. With 3 emitters a target can be defined in a 3d environment. With the HTS and passive equipment in general, ranges cannot easily be obtained. Time Differences of Arrival (TDOA) can be used to overcome the ranging problem. TDOA is typical for pseudo-range multilateration. The formula used to determine the amount of receivers to determine the location of the emitter is: m≥d+1 (d are the amount of dimensions being dealt with, and m the amount of receivers). To put it simply a TDOA solution in a 2d environment requires 3 receivers and a 3d environment requires 4 receivers. In passive equipment (yes there are exceptions but only in a cooperative environment) a single station, when receiving an emission, can only establish that an emitter exists. It can’t determine range or location for that matter (by using directional antenna’s you would be able to determine direction). A single TDOA requires at least two Times of Arrival (TOA). In other words, a single TDOA requires a minimum of two receivers. With a single TDOA a pseudo range can be determined which can be plotted on a half of a 2-sheeted hyperboloid (either the top or bottom in the picture). Adding a third receiver adds a second TDOA and hyperboloid. The location of the emitter in this case is on the curve (in red in the picture below) that intersects two hyperboloids. Adding a fourth receiver will have the previous curve intersect with the hyperboloid on a single point (most of the time as I understand it but apparently it sometimes can intersect in two points. I might be wrong here as I don’t fully understand this part). The point is the location of the emitter. With the visual examples as well as the formula I hope to demonstrate that locating an emitter with TDOA in a 3d situation requires 4 receivers. In the video by Matt, it is mentioned that at least 3 Vipers with HTS pods are required. To come back to my original question; how does ED tackle the TDOA equation with only 3 receivers? In the above quoted part it’s clear that KlarSnow is referring to 3d true-range multilateration and not pseudo-range multilateration. The picture provided references a 2d (on a single plane) TDOA which also only requires (2+1=) 3 receivers. The TDOA problem in DCS is a 3d pseudo-range multilateration so both the written as well as graphic representation provided in the solution don't apply.

  9. In the recent ED Matt video of the HTS improvement, it was mentioned you need at least 3x Vipers to get a TDOA solution. What is the reason for that? Edit: my mistake report in bugs wasn't intended. Please move to general.
  10. The way I interpret this is that a AG radar handoff is already as accurate as it can get. Makes sense because unlike the laser it's constantly ranging already.
  11. Might I suggest another improvement? The effects themselves are all the same. n Sure after fireFx in the zone description you can enter the required size. Would it be possible to enter "r" or "rnd" in the description so that DML then randomizes effects (fire / smoke), effect sizes (S/M/L/XL) and smoke density? To develop it further combine it with spot zone destruction. So you have randomized smoke/fire and combine it with say 60% (user changeable) of the objects at the fire/smoke destroyed? This would quickly add a lot of grittiness to scenario's that is randomized.
  12. Is there a way to randomize the position of FireFX in a zone?
  13. My bad. I forgot the reconModeConfig. It is properly mentioned in the DML Documentation but not really in the DML Quick Reference.
  14. cfxReconMode still returns altitude in meters and latlong even when MGRS and imperial is set to true. Is there a way to change it?
