  1. Hi folks,

     

    I'd like to put some of the Tiger's gauges on my iPad via Helios and Air Display if at all possible. Any simple guides or hints would be much appreciated. I've had a look at the Helios manual and seen some A-10C how to's on Youtube, but it's not coming together for me yet. Thx.

  2. Hi Folks, I've been using SweetFx for years now and generally, when people post screenshots, they will also include their actual preset as a starting point for people looking to emulate what they see.

     

    I perfectly well understand that the settings might have different results on different PC's, but I think that's something most people understand going in. Posting screenshots with vague references to what the settings are within the MEDIATOR capable of hundreds of different combinations within each option simply makes no sense to me. These aren't state secrets, after all.

     

    I've attached what I've got so far. :)

  3. Fog is not enabled by default in my install.

     

    This haze really has to go. It used to be that i could just make these changes to all view distances in the graphics.lua file and the haze would disappear:

     

    near_clip = 0.2;

    middle_clip = 4;

    far_clip = 600000;

     

    Now these changes have no effect. Any help would be much appreciated.

  4. Hi All -

     

    Has anyone figured out how to reduce the amount of haze in 1.5 stable yet? There used to be an easy mod of the graphics.lua which would make the haze all but disappear, but that doesn't seem to have any effect now.

     

    Thx,

  5. An excerpt from Radar, Heat, Guns by James C. Frederick, which i think you guys will appreciate:

     

    Let's talk about some things you already know.  You fly what may be the most capable fighter ever built for the mission we are assigned.  Great radar, great weapons.  Our best, most survivable scenarios involve using that radar and those weapons, keeping our mach up, and staying away from furballs.  Fly fast, blow their ass outta the sky as you pass 'em going Mach 1.  

     

    We are the biggest fighter out there and the easiest to see.  We get into a turn and burn scenario, in a multi-bogey environment, we are gonna have our hands full. But, all that said, it is gonna happen, ain't it?  The folks at McDonnell Douglas, bless their hearts, figured it would, and they gave us another great advantage for just such a situation.  We got power, and lots of it.  Have you tried the double-immelman yet?  You start at about 450, go max burner, ease into the first half of the double, and the second half ain't hard at all.  Plenty of power.  I've done a triple.  Yep.  We got power. But power, in and of itself, isn't an advantage.  It has to be managed as part of an overall fighting strategy.  That's called energy management.  Let's talk about it a little.

     

    First, the sticker on your brand-new F-15 says two engines that are rated at 25K.  That's a misnomer.  Rated power is kind of like Manufacturer's Suggested Retail Price on a new car.  It isn't the final number.  That thrust rating is on new, perfectly constructed engines, fuel controls tweaked, and at sea level.  When's the last time you flew around at sea level?  Engine wear reduces thrust over time.  Fact. But, the engines are really good, and they produce lots of power, and you have more excess thrust than the next guy in almost every fight.  Practically speaking, how do those engines work under the stress of combat?  Here's some practical-isms. The faster you go, the faster you go faster.  The slower you go, the faster you go slower.  Wrap your brain around that for a second.

     

    These engines love lots of air flow.  They are high bypass fans, and the efficiency of their thrust production is greatly affected by how much air is coming in the front.  The better the airflow into the front, the better out the back.  So, the faster you are going, the faster they will accelerate you.  That has a limit at the higher machs, where the drag induced by your jet at supersonic speeds finally catches up with the acceleration curve.  That drag curve is dependent upon what you have hanging on your jet and your gross weight.

     

    In dense, sea level air, induced drag builds up pretty fast . . air friction.  In an Eagle with one centerline bag and a full load of weaponry, you'll be lucky to get Mach 1.5.  More realistically, about 1.2 or 1.3 at low altitudes.  At higher altitudes where the air is thinner, same configuration, you can probably get 1.8 or 1.9.  Clean jet, you can probably do 2.0 plus. A MiG 23 will probably outrun you on the deck.  He probably won't outrun your AIM-7 or your heater, though.  Nobody, and I mean nobody, can out power you above 30.  In fact, we are in our element in a maneuvering fight above about 20.  Excess power, greater than almost anybody.  F-16 and F-18, more on our level.  Nobody else. Unless you are running from somebody or running somebody down, top end speed is overrated, anyway. 

     

    What you really need, especially in a knife fight, is the ability to accelerate . . to get slow and then get fast again quickly.  Lots of variables in the equation, but here's some generalities you can hang your hat on. 350 knots . . widely considered instantaneous corner velocity . . the minimum speed where full pull on the stick will give you about 7.2 Gs (momentarily) . . is a good cut-off point.  At or above 350, you have lots of air into the intakes and great acceleration.  As you get to 400, the acceleration accelerates, and you'll get to 500 from 400 almost as quickly as you got to 400 from 350.  The faster you go, the faster you go faster.

     

    Below 350, the other end of that weird cliche becomes evident.  You pull too hard on the pole, and even with max burner, you will probably decelerate.  Start slower than that, and you will slow down even faster.  The induced drag curve is steeper than the thrust production curve.  If you milk it . . if you limit yourself to 4 or 5 Gs, you can probably still go over the top . . plenty of power.  If you make that hard G turn with your nose pointed down . . use gravity to help you maintain your mach, you can probably maintain the G without loss of too much speed.  So, here's where energy management becomes a real tool in your kit.  You have excess power . . way more than almost anybody out there . . but it can be mismanaged.  Learn to know what your speed is without looking.  Learn to feel it, to sense it.  Learn to feel what the airplane is feeding back to you and how the airflow sounds over the canopy.  You start to feel the burble . . you are pulling the air off the back of the wings and inducing a lot of drag.  Maybe that's what you want, but maybe it ain't.

     

    Fight in the vertical.  Never give up that power advantage against a lesser fighter by staying horizontal.  Make him honor your ability to go up.  Most of the time he won't be able to stay with you.  Remember the physics of turn radius.  Faster speed . . bigger turn radius.  More than one good fighter pilot has found himself hanging in the silk because he forgot a really important fundamental.  You can't outrun a missile.  You might be able to out maneuver it, but you can't outrun it.  You have the greatest turn capabilities . . tightest turn, smallest radius . . at or near corner velocity.

     

    One last thing before I get off this soapbox.  Take a good look at an Eagle sometime.  How many tails we got?  Two.  There's a reason.  We have lots of rudder available, and the only reason for that would be high AOA maneuvering . . slow speed dogfighting.  Take a look at the outer third of the leading edge of the wing.  It has negative camber . . it actually bends downward.  Negative camber means the Eagle's wing does not stall wingtips-in like most swept wing fighters.  The wingtips, with that negative camber, will maintain airflow and resist stall to a very slow speed.  Good for  . . you guessed it . . slow speed dogfighting.  And one other thing about that squirrely negative camber . . it gives you a non-standard best acceleration flight profile.  Most fighters . . 0 G pushover equals best acceleration.  Our fighter, more like three quarters to a half G.  Rather than hanging in the straps, just get light in the seat for the best acceleration profile. If you are going to be a good dogfighter, a good BFM-er, you gotta know energy management.  It has to be instinctive.  You have to be able to fly your aircraft right at the ragged edge.  Keep your mach up and shoot 'em in the face, blow through.  But when the furball occurs, be the best.

  6. Hi All -

     

    A squad mate and I have come to notice that when launching an Aim-120c from our F-15's, 56 nm away while having an AI Su-27 bugged in TWS, that the Su-27 will immediately start pumping chaff out. If my understanding is correct, the Flanker shouldn't have any way of knowing that I've launched on him within the stated conditions. So why is he pumping out chaff? Please find tacview attached. This happened in DCS 2.0

     

    Thx,
