FC3 Bug thread

That is completely untrue. Missiles have no IFF capabilities.

 

5. Auto lock for missiles should not target friendly targets. That is one of the purposes of the Friend or Foe transponders.

I believe I've read somewhere that the real Su-27S has a target unlock button on the throttle. I don't believe there is a toggle function of the lock button in the real craft. Don't know about MiG-29 though.

 

In the MiG-29 there is a lock-on button on the throttle and an un-lock button on the flight stick - see attached images.

Hi sorry if this has been posted as i have heard about it. Two of my friends have recently bought fc3 and they happened to be flying f-15c's. I snuck up on them with irst and a lock. They reported mig-29s's searching for them on their rwr. before hand i did a similiar thing in a mig-29s but this time i was in a su-27. It seems irst in bvr mode is seen as a mig-29 radar pinging the f-15c. can anyone concur?

[FLANKERATOR]

Sometimes, radar turns on automatically while on IRST. It was at least a confirmed issue, not sure if that has been fixed in the latest version. Anyway, you can tell from the HUD symbology whether the radar is emitting, just keep your eye on the left side of the HUD and toggle radar on and off, you should be able to spot an indicator, then next time you stalk someone on EOS, you'd notice the second you start pinging. There was a debate whether the radar taking over EOS was a feature or a bug. I used to expect radar to take over as target starts changing aspect, if you want to remain silent then you'll have to turn EOS off before radar kicks in, then try to pick up the bad guy using EOS again. If unable, then he's likely closing in, your SPO maybe already confirming it.

[HiJack]

Have this been fixed in the upcoming release?

A minor graphic bug on the MIG29 HSI. The first digit of the DME readout actually sits outside the HSI overwriting the HSI surround. The digits on both DME and Course Digits don't line up with their respective tumblers. They all look slightly shifted to the left ... Layer alignment issue perhaps ?

 

Yet to check the other types.

 

You can't expect perfect lining in a cockpit without 6DOF, or you shouldn't.

Yeah, probably layer alignment or something similar, but show me if it happens in 6DOF F-15C cockpit... I didn't see it, but I believe it doesn't happen there.

In addition to what Flankerator said,

 

The Su-27 radar is larger(therefore more powerful) than that of the MiG-29, but their "signatures" are the same, so the reason why the RWR of the F-15 is showing MiG-29 although you are flying an Su-27, is because the RWR cannot determine whether the spike is a MiG-29 or an Su-27 further away and since the former would constitute the bigger threat(being closer), the the RWR always assumes that it is a MiG-29.

[arteedecco]

A-10A always starts with nosewheel / rudder at full deflection, both in-air and on ramp start (have not tried hot start).

 

Note, I disabled twist for X52 joystick and just use X and Y.

 

[EDIT]Similar to A-10C module, except with A-10A there's no "nosewheel steering" to turn on and center up the nose gear. Doesn't happen with other FC3 aircraft and I doubt that the A-10 nosewheel goes to full deflection when hydraulics are shut down IRL.[/EDIT]

[GGTharos]

I have some serious doubts about this. Optimal frequency and PRF turning can be easily related to antenna size. In addition, those radars may have common components, but they are not the same.

Possibly, but that was the explanation given as to why the RWR shows "29" for both types in the game.

 

In addition, those radars may have common components, but they are not the same.

 

Depends on what you mean by it - they are certainly built on the same design and IIRC share some 70-80% of components. The antenna is practically identical apart from size and the emitter output is also the same - whether PRF's are too to the point that they cannot be distinguished I don't know.

 

But at least it seems that whatever difference between them has much more to do with the associated WCS features(which so far isn't replicated in the sim) than the hardware itself.

[theChris]

Hello me again. I just played a very long game online with some friends. I had the same occurance happen when i am in bvr mode in a wvr fight (as you do with ruskies), and i turned my irst on (o) indicated by a t on the hud (note: there is no r under it... i am not a newbie) i found myself behind my enemy who was searching for me (who was also on ts). he promptly turned around as my irst was tracking him and we engaged eachother. r-27et and aim-120c at close range. We both died. He later told me i had my radar on and he got a mig-29 warning (which was my aircraft but the same occured to me in a su27 as previously posted). Obviously there is a problem with irst giving out radar waves to f-15c's rwr. I have always flown around without radar and irst, flying low and fast thinking i am invisible. This has mostly worked for me, but now i realize the enemies i have killed with ets were most likely novices, preoccupied or perhaps this irst glitch is a (not so) rare occurence. I plan on doing some more tests to make sure i am not half asleep when i turn my irst on etc.

 

Another bug with the irst i have found is as follows, when i am tracking a target, i always turn on the radar for a second or two to get the "F" on the hud for friendly or not. This also gives me a more accurate range to target. I tested with my friend doing the same trick but leaving radar on and he said he didn't get a solid lock tone. He was in a russian jet so i know that friendly radars are not dismissed (as i play flanker/fulcrum most of the time)

 

Another small bug i have found is aa vehicles such a buks tracking targets (me) whilst i am behind hills. I believe this is unrealistic for radar waves to act. I have reason to believe aircraft do this as well sometimes. But not enough evidence.

FC3 A10A Slats stay deplyed while flying around.

[71st_Mastiff]

FC3 A10A, not sure is this is supposed to be available for the A10A in FC3, CBU97's they do not deploy correctly in FC3 from the A10A..

[71st_Mastiff]

FC3 A10A the TGP seems to be available for the A10A on the weapons platform pylon 3.

Something from <<Electronic-Warfare-Fundamentals>> Chapter 17

 

Figure 17-8. Sample RWR EID Table

The EID table is a predefined table of radar characteristics associated with known radar systems

 

Figure 17-11. Signal Frequency Spectrum

Figure 17-11 depicts a number of friendly and threat signals that operate between 8000 and 10,000 megahertz.

On any given combat mission, it isquite possible that the RWR will receive signals from one or more of these threat systems at the same time.

If frequency is the only signal characteristic available for processing, the RWR will not be able to determine which system the signal represents.

Since threat systems operating in this frequency range are potentially lethal systems, the signal processor will attempt to match the frequency with a threat system from the EID table.

Any solved confirmation on some of these bugs?

Not 100% sure but during my flying in 1.2.4 I haven't had a single gear collapse, i'll go back and check some more today.

[arteedecco]

^^ Great to hear! I'm not saying I'm spectacular at landings, but it was a wee bit tough in 1.2.3 to get the FC3 aircraft down w/out belly sliding... at least with the F-15C.

[arteedecco]

FC... A-10A... in Nav mode (1), waypoints don't start from first WP.

 

For example, if I create a route in the ME for an A-10A (playable) and then jump into it (Multiplayer)... the first waypoint is actually the second one I created in the ME, not the start position.

 

I don't think it's just auto-cycling to the next waypoint (e.g. similar to pressing LCtrl + ~).

[TheMoose]

... MiG-29 or an Su-27 further away and since the former would constitute the bigger threat(being closer), the the RWR always assumes that it is a MiG-29.

 

Not sure about being a bigger threat ;) The Mig29 has R77 :D

Yes but the question was whether the known radar characteristics(EID table) of the N019 and N001 are so similar that they can't be distinguished.

[Alfa]

What I meant was that if the same "spike signature" can be either a MiG-29 close by or an Su-27 further away, then the MiG-29 would constitute the bigger threat simply because its closer :) .

 

The Mig29 has R77 :D

 

Well thats the thing - in the real world both types would most likely be employing the same BVR weapon(R-27R).

In the 3rd SU-27 Mozdok Campaign mission "relief", the SU-25s tasked with destroying the artillery tend to head home before having killed all the objectives, leaving me unable to finish the mission.

Generally, N001 is N019-Enlarged-version.

 

Attachment 2 shows the frequency characteristics of them.

Hi i had similiar isues but in one instance was able to complete the mission! Kill al the f-16s before telling the frogfoots to attack. However i played this mision multiple times and it could just be an ai bug, all other times they would destroy the buk radar then head home with ful payload minus 1 kh58. One way to complete would be cheating and turning immortal and unlimited ammo on and strafing with your mg. This is what i did on the mig29s mission similiar.
