Weight itself doesn't affect top speed, but rather affects acceleration towards the same top speed. One also has to take into account that the JF-17's RD-93 is not very powerful. Also, drag isn't linear with velocity and thus isn't 1:1. The JF-17 with the 2x PL-5 + 2x SD-10 is still able to accelerate towards the higher numbers, albeit slowly, due to the thrust overcoming the drag but the amount it is overcoming the drag is not that much, which is why it slowly accelerates towards the maximum. The GB-6 loadout isn't able to exceed the drag at ~Mach 1 with the thrust available to the JF-17. You can observe this behavior with other aircraft as well as this isn't a JF-17 exclusive thing. Also, feel free to read other materials available online that can help you understand aerodynamics. You can also look for the T.O. GR1F-16CJ-1-1 supplemental flight manual online and look at the level acceleration tables that detail how drag indices and weight affect distance traveled, time, etc., to reach a certain Mach number.

While the drag increase between the 2x PL-5 + 4x SD-10 loadout and the 2x PL-5 + 2x SD-10 + 2x GB-6 SFW loadout is only a 65% increase based on the Cx_pil values, that doesn't mean the aircraft will be 65% slower with drag being nonlinear relative to velocity. The reason why the GB-6 loadout "gets closer to its top end much faster" is because the ceiling speed limit for that loadout is lower than the 2x PL-5 + 4x SD-10 loadout, with the 2x PL-5 + 4x SD-10 loadout still having better acceleration. This comes down to general aerodynamics with the interaction between drag, thrust, and weight.

I don't know your testing parameters but in my tests, the JF-17 with CMBT engine mode, full internal fuel, QNH 29.92, +20°C, 30k ft altitude hold, starting speed of Mach 0.75 are this: 2x PL-5 + 4x SD-10: Max Speed of Mach 1.15 before complete fuel exhaustion 2x PL-5 + 2x HF20 - 16x BRM-1 rockets: Max Speed of Mach 1.04 before complete fuel exhaustion 2x PL-5 + 2x SD-10 + 2x GB-6 SFW: Max Speed of Mach 1.00 before complete fuel exhaustion With all three payloads generally starting to plateau in speed after 10nm traveled with the 2x PL-5 + 4x SD-10 loadout taking the longest to get to the max speed I recorded. The values presented for the HF20 with the BRM-1 rockets in the post by AeriaGloria are incorrect, as they have an effective payload drag value of 8.192 (0.002 * 4096) for one pod. I would personally attempt to double-check the payload drag values themselves for inaccuracies since the ones posted don't seem to be 100% accurate. I personally do not see anything wrong with the drag for these weapons. The only gripe I have would be the payload drag for the LS-6-250 being the same as the LS-6-500.

The dual SD-10 pylon loadout is ~6.16 (0.00150390623 * 4096), which includes both missiles and the pylon. Each missile itself in that loadout is ~2.64 (0.00064453124 * 4096) and that value is subtracted from the dual pylon loadout when the missile is fired. Same for the single SD-10 loadout which has a total drag value of ~2.64 (0.00064453124 * 4096) while the missile itself is 2.2. The drag for dual SD-10 loadouts are high but aren't that high. For reference, the AIM-120 LAU-115 2xLAU-127 dual pylons has a drag roughly of 8.027.

Thanks for explaining! I've implemented a new hint checkbox that users can enable that does almost exactly that: For the results page I've left it as is since I think it'll be less important after taking the quiz.

Ah, that's something you can enable with the "Show Radar Description" hint when you hover over a radar with your cursor. It's something you can disable/enable for added difficulty.

Heyo, thanks for the suggestion! I've just implemented it.

AGM-45 should be able to track sidelobes and backlobes since that is a basic requirement for ARM seekers. The HARM in DCS can also suffer from the same issue regarding sidelobes if the HARM were to attack from directly above the radar threat, thus this is indeed an ED weapon issue. Also, if the AGM-45 was able to pick up the SA-6 TR no matter the direction prior to launch but fails to guide post launch, that's a discrepancy between how the AGM-45 works while on the plane (HB side) and when it guides as its own entity (ED side).

I updated my site last week but forgot to post it here for you guys to see. The update included an updated site UI as well as a quiz page for you guys to test yourselves on the RWR library. You can change number of quiz questions, what symbols are tested, what threat categories are tested, and some additional hints for those who would like to make it trickier or easier when testing themselves. You can also share a link to your results with others if you want to show off lol. Also, one of the other changes I didn't previously mention that I had implemented was that the respective RWR symbol is now included for each sound in the RWR where possible. Feel free to post any suggestions or feedback! https://officialdsplayer.github.io/F-4E-RWR-PRF-Library/quiz.html

This month's patch included some changes to the HARM that were not included in the changelog. Now, a HARM upon target loss will attempt to hit the last known INS position of the target while attempting to search for the signal. The HARM is not laser pinpoint accurate in INS, but can still get close enough to kill the targets as is in your case. I will note that if you were to make the radars stop emitting even earlier in flight, the miss area would increase further. In previous patches (like the June patch), the HARM after target loss basically didn't fallback to its INS and continued the last command it had before target loss. That behavior was not correct. There are also some other HARM changes like I said, but they're slightly unrelated to this specific case.

Do you have any mods installed?

The LITENING TGP we have right now has unrealistically good lossless digital zoom which it should not have. The ATP implementation, however, does have the digital zoom limitations. Otherwise, I feel like the ATP is pretty easy to use, but the HOTAS commands are not the exact same as the LITENING's and I would suggest reading the manual chapter on the ATP to become fully acquainted with the system and how it works.

BAP-100 and BAP-120 are defined in CoreMods/aircraft/AircraftWeaponPack/common_bombs.lua

I would have to test it out again but I believe it does still work with the latest DCS version. If not, I'll have to update it.

What's the mission you're attempting this Mach 2 run in? The weather/atmospheric conditions do play a part in the maximum speed that you can achieve. I'm able to achieve Mach 2+ in level flight at 38000ft with a standard day.
