  1. Thats actually hilarious. My response that it, when reading from POV of another. I feel a little foolish. Well, only a little. In truth I dunno. However I think it does. 'Plus' variant was given F/A-18 radar for AIM-120 carry, to improve Harrier's AirAir capability. I imagine Plus having same fire control symbology as F/A-18 and F-16. For our N/A variant I dunno, but intend find out. I think, likely it does. Wether or not it is on RAZBAM's todo list is another matter.
  2. Well it is a commercial flight sim for entertainment and enthusiasts. RAZBAM has to implement it. A team has to programme it. Assuming that RAZBAM's AG gun's ballistic algorithm is solid, which it appears to be, and AA projectile path computation is solid, which it appears to be, funnel should be not be overly difficult. But it took RW Einsteins at GE 15 some years to develop a funnel for M61A1 on F16 . It still gets updated based on real world reports, and better CFD tools, and new ammunition. I am not a software engineer, but I do know that this stuff is sophisticated. From my artillery school days, the basic math is called Closed Loop Form Fitting Ballistic Algorithm. Model starts with round in a vacuum, with known muzzle velocity + platform air speed and directon vector, under Earth std gravity of 9.98 m/s^2, then drag is added using Standard Atmospheric Model (air density only, no winds, with 29.90 In-hPa), then mix in randomness to simulate mil deviation from tables published by weapon developer, and test firings of the weapon itself to gauge barrel condition, and some models implement Earth gravitational deviation. The ballistic algorithm then computes projectile trajectory, and reports that at specified rate to sim engine. The sim engine takes that trajectory and compares it to trajectory of target. If the two meet in time+space within tolerances, the sim engine calls the damage model, which computes hits, if any. Without radar or laser lock, the fire control computer has no way to judge distance, so it has to have an assumed target size measured in meters of the wingspan. Provided by pilot in RW , player in sim. Standard is 10-15 meter . 10 meters for F-16 (9.7 m actual), 10 meters for Mig-29, 12 meters for F-15, 14.5 meters for SU-27/30. The HUD funnel symbology is adjusted to desired wingspan. During combat, assuming pure or slight lead pursuit from 1500 feet (450 meter) on target's 8-4 aspect maneuver own ship as place wingtips to touch funnel sides, as seen through HUD, that means you have a good firing solution. Hold steady and press the trigger without jerking the a/c nose. So that is basics of using EEGS sight. It is sophisticated to develop, but relatively easy to use in a fast turning fight, where a snapshot with a gun is all you may get.
  3. Curious why my wingmen is running out of fuel, while I have plenty at end of mission. Wingman has same loadout, flies at same altitude, same stores. But runs out of gas 10-15 minutes before I do.
  4. I think that depends on your grossweight, a/c configuration, stores. If the center of pressure is aft of center of gravity, pitch up occurs. If COP is fwd of CG the pitchdown. Or is it vice-versa. The nozzle angle may be the critical factor. If nozzles are fully back flaps have small droop. As nozzle angle is increased the flaps follow. At maximum flaps are drooped so much that they act as airbrake, lift device, and ground effect generators. Last few feet prior to touchdown Harrier feels like a hovercraft. Even without H20 VSTOL , Harrier may be reluctant to settle. Especcially when it is light, all stores expended, and fuel is 750 TOT , and remaining H20 is 300 or less. The trick is to develop a feel for smooth slow throttle retard to touchdown. Practice practice practice. For VSTOL recoveries at less then 50kn KIAS or KIAS , nose into wind, I turn AWL ON, and Master Mode to VSTOL.The HUDSON symbology makes it easier to level and alight a/couple for two point toychdown.Harrier gear is strong, but if you touchdown on main first, the a/c will rotate down and bounce the front gear. By cycle gear likes nice two point touchdowns.
  5. DU hazard is not radioactivity. Its radioactivity is about same as raw U ore. Hence its name, DEPLETED. As fissionable istopes have been removed for nuclear fuel or weapons. They left over material is depleted Uranium. A dense heavy substance that in about 4 billion years will become lead. It has to be stored underground, and has little use. So someone in DOE back in 60's heard that USAF and US Army were working on kinetic energy munitions. A heavy dense substance accelerated to supersonic velocities has a lot of energy. Momentum = Mass * Velocity, basic physics. So DOE proposed using DU as penetrator cores to save money to DOD, and save money for DOE as they would not have to store material. Seemed like a good idea at the time. Today we know better, hindsight and all. The hazard is that it is toxic,a poison. It oxidises into UraniumOxide. It is carcinogenic, and there is evidence that it is teratogenic with possible epigenetic side effect. When it was stored or made into penetrators, there was little surface area for it to oxidize. It was not handled directly, so it was safe substance. But when it is vaporized due collision and heat, the surface area increases exponentialy and particle size is microscopic.
  6. Article of deployment of original AV-8 on CV's. So it is plausible scenario. Trying to find if CVN's have heat resistant deck modifications to landing area, to handle AV-8B or F-35B in VTOL or very short STOL. https://foxtrotalpha.jalopnik.com/the-time-when-av-8-harriers-deployed-aboard-a-fixed-win-1692022146 Spanish Navy Harriers on US Navy CV
  7. My first successful AV-8B Stennis recovery. Not the most graceful, or even per-rules, but no big kaboom either. Used about 2-3 fuselage lengths from touchdown. Look ma, no hook, no baricade! AV_8B_Stennis_Recovery_fair.trk
  8. Speaking of COIN, and thanks for triggering me, I so humbly wish, pray, desire, cry, weep, slit my wrists (only the right one) , for OV-10D Bronco/II module. Hands down the fineset COIN platform ever. Superior, even to today's A-29 Tucano. Despite my vehement objections, USAF/Reserve Command and Foreign Military Assistance Command have selected A-29 as standard COIN platform for low intensity conflicts. Keep in mind that Bronco could , with mission load, T/O and recover from aircraft carrier without hook, or launch assistance. Why USMC retired it after 1991 Gulf War, I do not know. Probably budgets. A modernized Bronco can carry Hellfire, UK Brimstone, ZUNI, TPOD, and operate in hot and high that helicopters cannot. It can land in a parking lot.
  9. L-39 is also a movie star. having been used in multiple James Bond films. F-5E is , by comparison , is the best 3rd Generation MIG produced by Northrop.
  10. Well, AV-8B does not have an active sensor , that can range an AA target. So it's all eye and feel, and Kentucky Windage. LCOS in F-15C, SU-27/33/J-11A provide pipper when target is radar locked. SU and J have fairly accurate EEGS gun funnel, for WVR gun fight without radar. A-10C has a fantastic EEGS funnel implementation, which I thought would be standard on all Gen 4 US types. LCOS that I am familiar with from days Falcon4 and Jane's F-15E is a 'snake' with range markers from 100 meters to 1800 meters. Or feet in 500 foot increments. I don't rightly recall. But the best passive sight is EEGS funnel in F-16 Viper. WHISH AV-8B had it. I have Mirage module , but have not yet trained myself on it sufficiently. Perhaps TPOD has an AA mode , as in A-10C, which can lase AA tgt for better guns firing solution.
  11. Does Vinson, Stennis, Tarawa, DeGaule, Kuz, and naval vessels with helicopter flight deck automatically turn into wind for launch and recovery? Regardless of what course the vessel's next waypoint . If not how do we make them? P.S. French Navy's DeGaul carrier has magically appeared in DCS encyclopedia as of 2.5.2.19682. Not complaining but I heard nothing about it.
  12. The pipper is not fixed. For either AA Guns mode. It dances small amount on HUD. Probably meant for WVR close combat of fighters with 10-12 meter wingspan within 1500 feet (about 450 meters) for Mig-29 sized adversary. But it is no EEGS gun funnel, thats fa'sure. I am not very good with AA guns in AV-8B. If SU-25 , when large pipper in centered on it, and Froggy's wing span is larger , in HUD, then pipper, I fire. Most rounds miss. A nice 1/2 second 25mm burst should perform in-flight disassembly of SU-25, but most rounds miss. What is infuriating is seeing tracers slide nicely in the trough where wing and fuselage meet, as seen from HUD,and not a single round connects.
  13. Isn't ramair an electric motor driven by impeller. It is the electric motor that spins the gun and powers the feed system. The motor itself is driven by ramair turbine, so it doesn't have to use onboard batterry. On ground, it is powered by cart. '
  14. Thank you for the correction. It is likely that DU rounds have been replaced with tungsten penetrator core. DU has been found to be persistent toxic hazard.
  15. Using -65E LMAV with ARBS, when TPOD is unavailable. Laser in ARBS?
  16. For single player. F-5E-3 module. You can take it from basic flight to combat training. It is not game-like as FC3 modules, has realistic systems, and is easy to fly and learn on. Warning! The following may act as 'trigger' for fans of DCS: Hawk, and DCS: L-39. Simulator in itself is about traning and entertainment. For me its a hobby of sorts, along with more serious Prepare3D. Having a trainer, inside a trainer seems, to me, redundant. However those training module have very detailed navigation system. F-5E nav is kind of simple. Which can be augmented with just released NS430 Pop-Up, assuming it is compatible with F-5E module.

  18. Here is GAU-22/A testing vid. I think that GAU-12 in DCS: AV-8B should sound similar, and even that GAU-22/A is 4 barrels and 3300 rpm rate. If anyone knows how to convert standard AIFF , QT mov, or Windows .wav into DCS sound effect. Please post.
  19. https://en.wikipedia.org/wiki/25_mm_caliber#Current_weapons According to Wiki 25X137mm round is same round for M242 Bushmaster chain cannon (M2, and LAV-25), GAU-12 5bl for HarrierII, and GAU-22/A 4 brl gun for F-35, and possible for F-16V Blk 70, and F-15X. APDS, HE, and tracer incendiary rounds are available. Rate of fire is 3600-4400 rpm, 3300 for GAU-22/A
  20. M242 Bushmaster is chain driven. GAU-12 is electric drive.
  21. I was Artillery, not Armor , in US Army, but yes, the Busmaster cannon in M2/M3(FIST) and LAV-25 is same single barrel cannon with 25mm with sabot, HE, incendiary, and blue training. There is also a 25mm Bushmaster equipped HMMWV that was fielded by US Army Motorized Infantry , and ABN, brigades in Panama , DS/DS. In NATO, any ammunition or weapon system that has blue stripes, blue paint, is training and is has no explosive or penetrator cores. The reel shows civi contractors handling blue rounds. The footage does show actual service sabots and HE being tested on old M-48 and M-113 hulks. Is it the same identical round as GAU-12, gotta research that one. In NATO there are multiple 30MM rounds , multiple 20mm, 25mm, and 27mm. It is absurd but the difference is in propellant casing and propellant itself. GAU-12 ammunition has to have sabot penetrators, HE, and incendiary. How Marines and Navy mix it for combat mix load, I am not certain. But for ground work, there is 1 APDS, 5 HE, 1 tracer/incendiary. Could also be 1 sabot, 9 HE, 1 incendiary. For anti-fast craft NAVY/Marines adjust the mix to threat. GAU-22/A modification, where 5 barrels are reduced to 4, is the gunpod for Navy F-35C and Marine/Rn FAA/NATO VSTOL F-35B with 480 round capacity. F-35A carries GAU-22 internally. Replacing traditional Vulcan 20mm with 485/515 magazine in F-15, F-16, and host of other types. Nothing approaches A-10 with its GAU-8 with massive 1185 capacity. The size of GAU-8, BTW, is not in the cannon, which is about same size as GAU-12, but in its massive magazine and feed system. There is a possibility of 4 barrel Equalizer from F-35 to be installed in new build F-16V and possible F-15X, and adaptations for LCS and small NATO surface combatants. As small craft and terror threats have magnified. Slovakia just ordered 14 new build F-16V/Block 70 airframes to replace its Mig-29s. Most advanced F-16 yet. ViperStrike beat out GrippenNG, according to Slovaks. LM is promising 10,000 hour life time for airframe. Thats 30-40 years. F-16 is going to be around for long time.
  22. Mav F is , D is with seeker modified for attacking moving targets at sea. The G is a much heavier longer ranged Mav for hardened targets.
  23. I think that the GAU-12 audio and rate are low. Kind of expecting something more similar to GAU-8 but not as violent. Found this little gem from 1979 from Navy China Lake on GAU-12 testing and eval/ Cheers
  24. OK, I thought that putting Master Mode to VSTOL, and flaps to either Auto or VSTOL, lowers flaps to 60 degree max droop (and Warn Light illuminates).
  25. Guns may, but rockets and missiles are inhibited from launching, due to flap position.
