AIM-7M sparrow & the RWR
-
re AS’s post - according to the (apparently not entirely accurate or uptodate) RP manual chaff is meant to be most effecitve vs ARH missiles from 8-6nm. once they are closer, the CCM tends to discount the chaff much more reliably. using chaff when its in close proximity isnt supposed to work very well.
i guess what he means by indefeatable is ‘undecoyable’.
anyway, i look forward to seeing what this aim-120 upgrade looks like if and when its finished if thats indeed what I-hawk meant…

Probably an improvement in the CD indexies (drag) due to CFD simulations, hence more range at higher altitutes and maybe not so easy avoidable with that “RWR 10 o´clock head-on dodging” anymore … just my guess
PS: at 6-8nm (if RP5 manaul is valid still) would indicate the moment of where the missile switches to independent or goes terminal, thus it would make sence to be “confuse-able” at that moment. But keep in mind, that at RP5 times there were no MPRF or HPRF stages introduced.

@A.S:
You keep saying “undefeatable”.
I really do not understand at all what your problem is with defeating ARHs in BMS???
Defeating ARHs in BMS is infact EASY in almost all situations - pretending one knows what he is doing in terms of BVR (and that without that “put the <m>symbol on 10 o`clock on RWR and break into it”</m> trick btw!).
In AF Aim-120s were much much more difficult to defeat… and in OF and FF ARHs were a friggn JOKE !!! …waaaay too easy - made by “modders” who only flew on “editors” or in F4browse and i am getting really tired to be told from those “desktop specialists”, who never appeared in any multiplayer human vs human BVR-events, how our missiles and chaffs are supposed to be :-? . “I can´t dodge a ARHs, so the code must be broken” is not the correct logic. Grr, sorry, but sometimes this make me angry.BMS is an excellent “balance” between AF and modFalcons imo… Not only that… it makes common sense in terms of what variables have to be generally considered in BVR engagements and missiles defensives.
Examples:
- Exploiting the proportional navigation and CATA intercept nature of the missile, meaning draging the missile to an extended lead intercept pursuit course where the missiles looses “track-angle” ability by overshooting its own FOV. (This happens as the missile is dragged into to parallel flight-path and due to its excessive speed, the target falls behind its own seeker FOV).
- Exploiting Line of Sight (LOS) rate, meaning flying as fast as possible 90 degrees to the inbound missile in order to exploit the seekers update-rate (works nice versus Aim-9x ie.)
- The Beam or the Notch at possilbe ranges (those are clear in BMS) to break the tracking-guidance aka the planes radar first. As example to defeat semi-actives as they require constant lock till impact or to break locks of actives before they enter the terminal stage (this is where chaffs would matter), or to break lock of bandits before actives go MPRF > HPRF.
- Using Groundclutter to confuse the tracking or guidance with radar-returns from the ground (“look down” of missile radar).
- Geometrically, meaning fighting the missiles maneuverbility due to its exessive speed (Gs and turnradius).
- The Sun as distraction for heat-seaking missiles.
- Rmin, meaning exploiting the missiles fusing-time by staying closer to the launch-plattform (if possible).
- Most importantly and probably prior to all others >> Kinematically, meaning bleeding the missiles energy by provoking increased drag in its initial or/and terminal flight-path. Clasic example would be a cold “snaking-maneuver” versus a missile with possitive closure i.e. or an initial intercept path determination and energy bleed-off as missiles flight path obeys your own trajectory.
- using lower altitutes against the missile (higher drag)
- using higher altitues against the missile (drastically reduced turn-abilities)
- and last but not least CHAFFS and FLARES as distraction or as LAST INSTANCE to increace the miss probabilities, whereas “miss probabilities” are puropsly minute (as described above) and are not “fail gurantees”.
- etc etc …
All those things WORK in BMS !! (see tapes below).

http://www.as-private.com/ACMI/excuseme.acmiIf you really think, that countermeasures (chaffs) are the only (or the most the important) method to defeat ARHs, then i think you have missed a whole chapter in missile defense.
it is broken. in the code it says that chaff can decoy it, in actuality it cannot. if you think that it should be undecoyable, that’s fine. but the fact that it’s undecoyable ignoring it’s own decoy % is clearly a bug and should be fixed. you don’t need to defend the sim as infallible. while it is truly excellent, this tiny bit of it doesn’t make any sense.
if you think the AIM-120 should have a 50% decoy chance or a 100% or a 0% doesn’t matter, that the missile effectively does not obey the way it’s supposed to work is a definite bug

I-Hawks comment blurs the line between bug and feature…

Do you have access to the BMS code to make such a claim?
-
Indeed. the percentage is irrelavant in this experiment as we analyse the function itself. What kind of objective tests have you done to support that claim? Elaborate.
-
Define “the way it’s supposed to work” according to your opinion? or to real world documenation or logic?
you don’t need to defend the sim as infallible.
I don´t, because i don´t observe what you observe and for me things make sense from the falcon-logic perspective. I remember the “why it was done that way” in order to have a compromised tactical semi-realistic solution. Chaffs deployed at the right situations and moments do make sense in my install.
Ps: On the other hand i must agree, that it is almost irrelevant in what quantity and quality (sequence or programing) chaffs and flares are deployed.
HERE i would love to see improvemts aswell.cheers

Quantity of chaff deployed basically IS irrelevant. Deploying two packets of chaff at once does not give the chaff bundle a bigger RCS.

Two at once most likely not (seen from your logic above). But there is a reason for sequence-control (amount and intervall) of countermeasures.
Or do you think, they implemented that into the F-16 because it looks funnyPS: Also it is not sound, i still use different programs for 1-4. One (1st Prg) chaff program for defending missiles close up… another (3rd Prg) totally different one for fighting enemy airborne radars.
That´s what im using currently - personal preference!! - and not mandatory.
-
well, no arguments over the implementation of the countermeasures dispensing AS. I suspect they implemented it into the F-16 in BMS because thats the way it is in the real jet, without concerns over whether the real jet looks funny.
-
Of course.
Search into the Electronic Warfare Fundamentals the chapter about RWR and limitations. (Chap17 If I remember correctly)
…
Chapter 13 it is.
I also have shit loads of material on that topic i believe.

i dont think its to do with the PRF mode switch, but the mathematics of the seeker and RCS modelling etc.
