  1. everyone that poo poos that A-10's survivability must have a short memory. remember that little adventure in the desert called Desert Storm? after 10 years of getting equipment from the east and west; the Iraqi army didn't blow the entire a-10 deployment out of the sky in the first 24 hours. The A-10 was designed to survive and effect the battle space in a high intensity contested environment. as an aside, from memory it was actually the F-111 that killed more tanks that any other aircraft in the gulf war. it had a better range and payload than the strike eagle, and was a better low level strike platform; didnt stop it from getting the axe 4 years later.
  2. thats the whole point, unless the BC, mass and the velocity of the projectiles were identical you would never get an identical MPI throughout the range on the weapon. What Emu is saying is that if you slowed down the API round, so they that both would have an identical MPI at say 1800m (1nm), then the HEI MPI would be above at range shorter, and the API would have an MPI above at ranges longer. this is the mechanics of ballistics and trajectories. i havent tried it, but certainly you might find the MPI reverse at ranges around the 300m mark on the reticle. the muzzel velocity of the API round is actually a good few hundred FPS slower than the HEI round. but like anywhere else, it is BC and momentum that dictate terminal performance and how "flat" a projectiles path is at longer ranges. a good example would be to compare bullet drop at ranges past 500m for the 5.56 and the 7.62 NATO ball ammunition. *BC ballistic co efficient *MPI mean point of impact edit: oops sniped ^
  3. i dont expect belsimtek would do it, since the aircraft are substantially different, but how hard would it be for a modder to "get close" the CAC-27? two 30mm aden cannons and the avon engine. the extra 400kg of pork must have been in the guns, since the avon was apparently lighter than the J47.
  4. as far as i can tell, it happens at low airspeed, high AoA, and bashing the throttle from idle to full. no need to restart the engine, just set throttle to idle, put her in a bit of a dive, get some airspeed, the smoothly apply the throttle to see if you have cleared her out.
  5. well those who use the military as instruments may not have learnt, but the military sure has. One in 5.5 Australian military personnel who served overseas were killed in action/died whilst deployed in the first AIF. 500 died in Vietnam out of 55,000 that rotated. 41 and counting in operation slipper. i still cant get over that first statistic. I can only be in awe of the generation that lived through two world wars, the great depression. then witnessed the nuclear arms race. and those that survived the great war then were subject to the flu pandemic which claimed more lives that the combined civilian/military casualties of the great war. But. Appeasement is not automatically the right course of action.
  6. even with unguided munitions, artillery is generally very accurate. the area "saturation" as it has been put, is actually something deliberately plotted by the gunners on the firing line. all arms call for fire procedure will include in the target description the size of the area. ie infantry dug in 400 by 400. the FO will then pass on to the gun line in that scenario to use delay detonation fragmentation rounds, and to set the battery to fire within that box. asuppose to infantry in open, you would use air burst, and armour would; if available, mean a different ammunition nature again. the real value of GPS/INS guided 'bombs" (thats what the cloud punchers/ kabana boys call them) is when you are using RA munition (rocket assist) and you have a "danger close" type scenario. RA increases your planning range; as an example the 105 round from about 10,000m to 27,000m.that greater range and the RA obviously blows out the accuracy. the 155 shell which is becoming the NATO standard has an even greater range than that. it was under these circumstances, they were frequently using them in Afghanistan. also works when you dont have any direct fire platforms in range, and you want to level one building, but not the building next to it, which is what the IDF would be using it for. the IDF has actually gone to great lengths to develop PGMs that minimize collateral damage, even though, contrary to the media and ban ki moon's bleating, is permissible under LOAC. And I can tell you for a fact, the Germans most certainly use it, and so do we.
  7. i gotta say, I tried the the fishbed after having no luck after hours locked in with the fagot. and much to my delight, i actually got rounds on fairly quickly. this didnt lead to a splash, but was satisfying none the less getting a streak of hits down the fuselage. at least much more satisfying than spending 10 minutes turning, then 30 seconds climbing, and repeat with the fagot. the mig-21 was apparently an even match for the f-4, following the experiences in Vietnam, perhaps it makes sense the sabre can down the fishbed in a gunfight?
  8. hmm, I was sure it was what is depicted in ARMA II "Chenerus"; BI used terrain data in the Czech Republic for "map". Looking at that photo however I'm not so sure???
  9. you should be able to get a lock at about 7nm with the 65D, the osa will fire at about 5nm. you can of course use force correlate as suggested.
  10. anyone else recognize the TV/Radio tower at about 5:00???
  11. i thought she was going to be a real handful; swept wings, relatively powerful, no control augmentation. but jeez i was surprised first time i took her for a spin, she flies like she is on rails, easy to manage in a tight turn, and recovers very easily from a spin. the only thing I find disconcerting is the how quickly you bleed air speed once you drop full flaps, have to pay attention to the power. still, a shit tin easier than landing the p-51.
  12. wow,if you had the meteor, the sabre, and the p-51, thats a fairly comprehensive sim of the latter part of the korean conflict on the UN side, bar the panther. good luck with it!
  13. isn't she F**KING beautiful!! 1st time: take off, ascend to 20k ft, then land back at Senaki. she really does fly like she is on rails. its hard to believe there is no SAS (right?) what a work art. thanks BST and ED.
  14. its a bit unusual for the poms to sell their decomissioned gear isnt it? only tornado to be sold to the public, harrier took part in the Falklands... they will go for a pretty penny... parts for the tornado would be rare as rocking horse shit, would be a fun exercise to get it airworthy. could only dream that they get donated to Duxford? Richard Branson likes things that go zoom zoom right?
  15. yeah, it looks as if it went down in northern mali, so you definitely couldnt categorically say it wasnt shot down, but given it would have probably been at cruising altitude, bad weather is the far more likely cause. according to wiki, 7 airliner incidents this year. which doesnt seem unusual, the two MH losses are extraordinary obviously. http://en.wikipedia.org/wiki/List_of_accidents_and_incidents_involving_commercial_aircraft#2014 we have had a few light plane crashes in Aus already, which seems up on the average. one was caused by a broken seat bracket, one by the pilot trying to land at night on an unlit strip, another crashed shortly after takeoff, havent heard the cause yet. could be a reporting thing but.
  16. my bad, was actually a dash 8
  17. they had some landing gear problems, remember that Air Newzealand one that made a belly landing a couple of years ago? id say their poor safety record is more attributable pilot error and maintenance issues, ie small commuter airlines operate them frequently.
  18. Another thing people should bear in mind before leveling culpability or liability at the airlines that these particular set of circumstances are UNPRECEDENTED. The closest set of facts to these circumstances is the Vincennes-Iran Air shoot down. A couple of planes have been shot down on final or take off in Africa, airlines frequently seem to maintain services despite significant manpad threats, look at the circumstances surrounding the Air France Hijakcing in Algiers. It seems that it wasnt common knowledge that Buks had made it into the hands of the separatists, the fact that delta was one of the few if not the only carrier that avoided the airspace tells me that had specific knowledge of some sort. looking at it legally since some people are throwing legalese around... foreseeability - bugger all, it might seem "obvious" to some you, but since many many flights make these trips over contested airspace everyday for years makes it unforeseeable. hindsight is irrelevant. the reasonable airliner - they were all doing it bar a certain few exceptions, and this has been a long time practice since. Clearly this will change, again hindsight is irrelevant. will they pay out the familys anyway? most likely. but bear in mind the US government paid out compenstation after the Air Iran shoot down. Can't see the separatists or Moscow (if it discovered they actually supplied the weapon system) doing the same. hence the fault lie with those that pulled the trigger. not the airliners as some of you assert. I actually feel sorry Malaysian Airlines, what a shit run of luck, and may well be the last nail in the coffin for them. perspective seems an increasingly rare commodity.
  19. whats coming through the media now is that a number of governments including the US and the UK had issued warnings about flying over eastern Ukraine, but only Delta airlines had heeded those warnings. both Lufthansa and Singapore airlines were in close proximity, and almost certainly within tracking range when the shootdown occurred. hindsight is always clarifying. the location itself seems too far away from the russian border to have been shot down by the Russian IAD, lest the extremely unlikely event that something like a grumble was involved. As one of our "experts" (Paul Dibb) put it: "this is what happens when sophisticated equipment is in unsophisticated hands". Yank ISR assets most likely know exactly what happened. the only question will be whether the Buks were captured Ukrainian, or came from "another 3rd party". the western media certainly aren't pulling any punches.
  20. Flying over a warzone might seem absurd in hindsight, but from some informed accounts I have received it is not at all unusual. I have a family member who flew with qantas in the 70's and recounted watching the battles over the golan heights; both sides in that conflict had some serious AD and hair trigger to boot. it is plain as day what has happened. If I were the Malays I'd be pretty pissed that the Russians have snuck off with FDR's before the wreckage has cooled. It wont matter though, the NTSB and the Malays will want in. Once the explosive residue gets collected, and radar data analysed, there will be little reasonable doubt. there will be no convincing the tin foil hat brigade either way. Oh and last time the Ukrainians shoot down an airliner by mistake, it was during a live fire exercise that went horribly wrong, and it was a Russian flagged aircraft. Oh and for any suggestion this will broaden the conflict... remember KL 007? that happened during Able archer, and at a time that the cold war got warm (up there with the cuban missile crisis) and there was not much that happened in the aftermath, both sides reacts with cool heads. To anyone reading with relatives or friends on that flight, my most sincere condolences. Australian media hasn't released the list of our dead yet.
  21. the value of academic or research papers pales in comparison to the experience and knowledge of people who HAVE WORKED AND OPERATED WITH particular equipment. you can read shit off the net, paid or free untill you are blue in the face. it doesn't compare with having the pam infront of you, nor the experience of how it works in the field (and believe me there are discrepancies both ways on that issue). its fairly clear that only two posts in this thread have substantive value.
  22. thanks for that post Hoss, very interesting. stuff must have changed a fair bit over 20 years right?
  23. i reckon FC3 is worth it for the F-15 PFM alone. the added bonus will be the PFM for the Su-27 is coming out sooner rather than later. Su-25A is a hoot as well. FC3 is really just an intermediary for when i get sick of the Hog from time to time; IMHO it is an entirely different game. And once you learn the key strokes for one aircraft, you more or less know them all. The Su-25T is probably the most complicated at the moment in terms of avionics, except for the eagle where you can disable the CAS; the auto pilot only has attitude hold at the moment too. other than that using the fire control systems is very easy, other have similar key bindings to the A-10C like gear, flaps, and slew control.
  24. remember when a embrauer business jet impacted a 737 over brazil? the business jet's winglet impacted and severed the boeings wing near the nacelle. the smaller jet landed safely, the 737 didnt. regardless, a bad run the eurofighter at the moment.
  25. the combat loss exchange ratio in the Korean conflict would imply that your statement is utter balls. id buy a mig-15. i thought it was on the forecast for belsimtek?
