MACH NUMBER and AIRSPEED vs ALTITUDE MACH NUMBER is defined as a speed ratio, referenced to the speed of sound, i.e. Mach Number = Velocity of Interest / Velocity of Sound (at given atmoshperic conditions) Since the temperature and density of air decreases with altitude, so does the speed of sound, hence a given true velocity results in a higher MACH number at higher altitudes. AIRSPEED is a term that can be easily confused. The unqualified term airspeed can mean any of the following: a. Indicated airspeed (IAS) - the airspeed shown by an airspeed indicator in an aircraft. Indicated airspeed is expressed in knots and is abbreviated KIAS. b. Calibrated airspeed (CAS) - indicated airspeed corrected for static source error due to location of pickup sensor on aircraft. Calibrated airspeed is expressed in knots and is abbreviated KCAS. Normally it doesn't differ much from IAS. c. True airspeed (TAS) - IAS corrected for instrument installation error, compressibility error, and errors due to variations from standard air density. TAS is expressed in knots and is abbreviated KTAS. TAS is approximately equal to CAS at sea level but increases relative to CAS as altitude increases. At 35,000 ft, 250 KIAS (or KCAS) is approximately 430 KTAS. IAS (or CAS) is important in that aircraft dynamics (such as stall speed) responds largely to this quantity. TAS is important for use in navigation (True airspeed ± windspeed = groundspeed). Figures 1 and 2 depict relations between CAS and TAS for various altitudes and non-standard temperature conditions. The first graph depicts lower speed conditions, the second depicts higher speeds. As an example of use, consider the chart on the next page. Assume we are in the cockpit, have read our IAS from the airspeed indicator, and have applied the aircraft specific airspeed correction to obtain 370 KCAS. We start at point "A" and go horizontally to our flight altitude at point "B" (25,000 ft in this case). To find our Mach, we go down vertically to point "C" to obtain 0.86 Mach. To get our TAS at our actual environmental conditions, we go from point "B" vertically until we hit the Sea Level (S.L.) reference line at point "D", then travel horizontally until we reach our actual outside air temperature (-20EC at altitude) at point "E", then go up vertically to read our actual TAS from the scale at point "F" (535KTAS). If we wanted our TAS at "standard" temperature and pressure conditions, we would follow the dashed lines slanting upward from point "B" to point "G" and read 515 KTAS from the scale. Naturally, we could go into the graph at any point and go "backwards" to find CAS from true Mach or TAS. Figure 3 shows a much wider range of Mach numbers. It contains only TAS and Mach, since aircraft generally do not fly above Mach 2, but missiles (which don't have airspeed indicators) do. The data on this graph can be obtained directly from the following formula for use at altitudes of 36,000 ft and below: Speed of Sound (KTAS)’ 29.06 RADIACAL/of( 518.7-3.57 A) Where A’altitude (K ft) The speed of sound calculated from this formula can be used with the equation on the first page to obtain Machnumber. This equation uses the standard sea level temperature of 59E F and a lapse rate of -3.57E/1000 ft altitude. Temperature stabilizes at -69.7E F at 36,000 ft so the speed of sound stabilizes there at 573 knots. See the last page of this section for a derivation of equation [2]. ..hope that helps a bit...i saved this while back, cause it is pretty good explained... (PS: i do use also MacH in Lockon in order to know my best "turnperformance" at different altitutes)

:pilotfly: Download link: http://www.fileshost.com/download.php?id=83109EAB1 or Lock on files Install via Modman

created a campaign "Crimean crisis." True even two campaigns, First fo blue coalition, second for red. Today, for the blue. (red while testing). For normal work you must install the mod Merzifon http://www.lockonfiles.com/modules.php?name=Downloads&d_op=search#searchresults http://forums.eagle.ru/attachment.php?attachmentid=28751&d=1246618515

Can anyone tell me please if it is a known bug that with realistic G setting in Lock On there is no red out when you pull negative G? Thanks

Dont get me wrong but the source of your evil is mach 2.5 AMRAAM's otherwise you woudnt see F-15's doing Split-S's repeatedly to re-engage for low PK missiles. Had it been a mach 4+ missile in the first place, what would you see would be F-15's doing F poles and drive you defensive the moment the missile goes active without giving you the chance of keeping the lock while dodging. ED needs fixing the missile so you wont have to be frustrated by this tactic. theres nothing LRM can do to avoid it. BTW migs do the same "tactic" as well, just as the flankers do with ET's. And they all have donne this for years. Dont blame LRM for this missbehaviour.

Nothing more solid than you can already read: http://forums.eagle.ru/showpost.php?p=711173&postcount=12 But on SimHQ people interpreted this the same way and it makes sense with the statement for digital adjustable resistance. :smilewink:

No problem, I'm having my own little nightmare with Catalyst drivers too (new ATI card) I'm never buying ATI again. Question for skypat, could you direct me to some information on how to start DCS.exe with a very simple mission on its own, without first starting launcher.exe. I am assuming mission selection is done with something like command line parameters or a simple cfg file, only i can find it. Nate

А к blender'у плагины будут? А то уж больно дорого 3dmax покупать...

My best wishes!

All the best!

All the best! Let your wishes come true :)

And why you never see anyone walking around...

Если искать недостатки ,то можно найти не особо утруждаясь... ЧА - это симулятор вертолета,военного ,имеющая и аркадный режим для Всех пожелающих.И это хорошо. В АрмА2 убогие вертолеты и техника(ее управление), но симулятор то чего? Правильно - пехоты,бойца и очень даже хороший,со своими недостатками...а не симулятор техники. Ну вот и в Акуле приоритет отдан не пехоте... Никто никого не "обвешивал".Это не воздушная мясорубка . ЧА - это самый серьезный симулятор вертолета.(И он постоянно улучшается)

:shocking: и это военный симулятор?

The end of your story sounds almost like a delicate party ala FalconAF BVR, where some mysterious figures try to defeat me with abstract callsigns, either blown out of my airspace or moving along in "shaking" illusions...:megalol: :music_whistling: (nice read)

Hope you had a good one! Happy B-day.

Is that the famous Superhero guy kinda?

Nice skin, good job :thumbup:

Nice!

Happy Birthday X-Man :)

With or without LRM comrade Tito will get you. But he feels better when he gets you with LRM :P Reason is very simple- LRM helps me better understand why I'm succeeding or failing. But as a rule I never fail, I just fall in some world conspiracy traps from time to time.

Сдесь постаянно звучит фраза КА-50 это серьёзный симулятор (даже мелькало " ЭТО ВАМ НЕ БЫДЛОАРКАДА" ... но тогда как себя чуствовать при стрельбе по живой силе противника !!!(да и по движущейся технике тоже) я НЕ говорю щас про легендарную стрельбу наром которым надо попасть в голову пехотинцу чтоб тот поменял положение из стоячего на лежачее ... опять же приведу срвнение из тогоже ИЛ2 ..с самой первой версии (а это господа середина 20 века) - там поведение пехоты (в том числе и пилотов оказавшихся на земле) вполне одекватно происходящему, тоесть люди бегают ложаться и закрывают голову руками ,при поражении пехотинца тот занимает живописнейшую позу "умирающего лебедя" живописно раскинув ручёнки с ножонками... таже техника там (не вся)когда на неё заходиш сьезжает с дороги в выкрутасе и начинает вести по тебе огонь... Сдесь же при стрельбе по пехоте чусвуеш себя ну неточто играющим в "быдлоаркадку" ,а зрителем в театре абсурда в котором тебе дали роль... тоесть всё ТО ОЩУЩЕНИЕ ВЕРТОЛЁТНОГО БОЯ С "ЗЕМЛЁЙ" улитучивается чудеснейшим образом. почемуто появляется жгучее желание поскорее закончить этот бред и невозвращатся к нему !!!!! МОЁ мнение по этому вопросу если уж пехота такая то лучше вообще никакой , покрайней мере небудеть возникать чуство что тебя в очередной раз "обвесили" .

Thanks all!!! :D

Also , when looking at the camera view/tracking screen, more sure that the IR leds are fairly centered in the camera view, which maximizes the cameras ability to track you with the greatest amount of freedom.

Do you have the trackir device clipped to the left hand side of your monitor ? It isnt meant to be in the centre of your monitor if using the track clip pro. It is only meant to be in the centre if using the metal frame thing you use with hats, but if your using the track clip pro then the trackir device should be on the left hand side of your monitor as you are looking at it.
