FWind Posted September 4, 2018 Posted September 4, 2018 why the SP PD position is only used with AIM-7 and NORM position used with AIM-7 in CW mode or used the AIM-54 in semiactive guidance mode？
Blaze1 Posted January 28, 2019 Posted January 28, 2019 It may be a compatibility issue. Earlier versions of the Sparrow were CW only, with the 'F' model being the first to support pulse doppler.
Naquaii Posted January 28, 2019 Posted January 28, 2019 NORM sets the normal launch mode logic (CW for SP and PH according to radar mode) while SP PD sets pulse doppler for newer AIM-7 and PH ACT sets phoenix to launch active.
Blaze1 Posted January 29, 2019 Posted January 29, 2019 The 'A' model Phoenix was older than the AIM-7F and this could be one of the reasons it didn't/couldn't benefit from PD illumination. I don't know if the Phoenix 'C' suffered from the same limitation.

kotor633 Posted January 29, 2019 Posted January 29, 2019 By the way, one Question to the Sparrow Missile: Which Version of the Sparrow can our DCS Tomcat carry? Only the AIM-7E-4 Version? Or maybe a newer version? ************************************** DCS World needs the Panavia Tornado! Really! **************************************
turkeydriver Posted January 29, 2019 Posted January 29, 2019 By the way, one Question to the Sparrow Missile: Which Version of the Sparrow can our DCS Tomcat carry? Only the AIM-7E-4 Version? Or maybe a newer version? AIM-7E-4 all the way up to the latest AIM-7 in the game. VF-2 Bounty Hunters https://www.csg-1.com/ DCS F-14 Pilot/RIO Discord: https://discord.gg/6bbthxk
Naquaii Posted January 29, 2019 Posted January 29, 2019 Yeah, we will eventually have the AIM-7E2 up to the AIM-7M. And the AIM-54A uses pulse doppler illumination, that's the normal mode for it when not set to active at launch.

CarbonFox Posted January 30, 2019 Posted January 30, 2019 I also understand that ED is working on the AIM-7P which added mid-course correction capabilities and better low-altitude performance. Will this also be incorporated into the F-14? F/A-18C; A-10C; F-14B; Mirage 2000C; A-4E; F-16C; Flaming Cliffs 3
Naquaii Posted January 30, 2019 Posted January 30, 2019 Which mode the AIM-54 use CW illumination？ It doesn't. Only the AIM-7 uses CW. If the -P is introduced in DCS we'll have a look, I haven't read up on it so not sure if the F-14 used it.

Naquaii Posted January 30, 2019 Posted January 30, 2019 Is the AIM-7 in PD have something different with the AIM-54 in PD？ It works more or less by the same principle but different frequencies and commands.
FWind Posted January 31, 2019 Author Posted January 31, 2019 It doesn't. Only the AIM-7 uses CW. If the -P is introduced in DCS we'll have a look, I haven't read up on it so not sure if the F-14 used it. So the CW illuminator only Uesed with the AIM-7.
WindyTX Posted January 31, 2019 Posted January 31, 2019 Nice thing about selectable CW illumination is you can fake a launch without actually launching a missile.

Dudikoff Posted January 31, 2019 Posted January 31, 2019 (edited) Nice thing about selectable CW illumination is you can fake a launch without actually launching a missile. If the switch is in the NORM position, does the WCS always trigger CW illumination no matter the AIM-7 variant carried? I guess the monopulse seeker in the later Sparrow variants can lock on to CW illumination as well, but if the WCS follows the same CW illumination/launch logic, does e.g. the AIM-7M seeker then needs to be locked on to the target before it can be launched (as this would shorten the maximum launch range)?

Yes, the later sparrows afaik were also capable of using CW as a kind of fall-back mode. And yes, in NORM CW will be used, you have to set it to SP PD to use pulse doppler. That said, an rwr will still be able to see the AWG-9 doing "new" stuff indicating a missile launch so the effect in DCS will mostle be missile range. The AIM-7 PD works differently than the AIM-54 which only requires momentary illumination and commands from the AWG-9, the AIM-7 is used in STT and requires constand PD updates and illumination.
turkeydriver Posted January 31, 2019 Posted January 31, 2019 The VF-1 Tomcat that got an Mi-8 kill in Desert Storm had the AWG-9 fail IIRC but stated he could still use his AIM-7 in degraded mode- I wonder if he meant illuminator only since its seperate VF-2 Bounty Hunters https://www.csg-1.com/ DCS F-14 Pilot/RIO Discord: https://discord.gg/6bbthxk

Yeah, I'm aware that AIM-7 requires an STT lock (except in FLOOD mode), but I specifically stated seeker lock before launch (LOBL) which is a different thing. So, just to reiterate, if I launch an AIM-7M in CW mode, I presume there would be no mid-course updates sent via PD mode and the missile seeker would then require a direct lock to target (which shortens the launch range to e.g. 20 km for a fighter sized target)? Because, normally, AIM-7M flies to an intercept point and receives corrections until it reaches the estimated seeker range where it activates the seeker and tries to lock on to the illuminated target (so, the seeker is in LOAL mode at ranges beyond its lock range), but I'm wondering what happens with it in CW mode.

Afaik, in CW it's pure CW, so no PD updates.
Dudikoff Posted February 1, 2019 Posted February 1, 2019 Afaik, in CW it's pure CW, so no PD updates. That's what I thought, thanks. But, then, the maximum launch range should be shorter as the seeker needs to get a lock on before launch, which begs the question if this could (and would) be simulated in DCS? :) i386DX40@42 MHz w/i387 CP, 4 MB RAM (8*512 kB), Trident 8900C 1 MB w/16-bit RAMDAC ISA, Quantum 340 MB UDMA33, SB 16, DOS 6.22 w/QEMM + Win3.11CE, Quickshot 1btn 2axis, Numpad as hat. 2 FPH on a good day, 1 FPH avg.

Naquaii Posted February 3, 2019 Posted February 3, 2019 The next launch button sets prio 1 for TWS launch to the hooked target. As for CW and range differences we'll see if we can implement that.
