True Altitude?

[Soldier_Fortune]

Hi Jeremiah. Thanks for your interest.

As I already stated, in this sim there is not difference between Indicated Altitude (the altimeter reading) and True Altitude (altitude affected by local pressure and OAT at a given altitude). But True Altitude is modeled in other sims (i.e., LOMAC Flamming Cliffs 2).

Will True Altitude be modeled in IL2 in a next future? Really I don't know. But if TD decides to model it, True Altitude will affect the level bombing. In any case, it can be easily calculated with an E6-B, as actually TAS and Ground Speed must be calculated for an accurate level bombing.

Also, you don't need adaptive bombing. There are definite formulas that are used, but some planes use slightly different values. Also, the IAS/TAS chart that's in the game is only giving you the partial equation...so the values for TAS are usually WAY off. That chart shows the aircraft's speed increasing linearly (on a straight line), but it actually increases on a curve. Fortunately, you don't need a differential equation to calculate it...a simple polynomial is all that's needed. In other words, basic mathematics. LOL
And yes, OAT (Outside Air Temperature) is very important for calculating that curve.

I was trying to express all those formulas with a set of printable graphic charts for manual release of bombs in level bombing.
I personally am quite skillfull handling the E6-B and I have no difficulty solving all those equations with it while flying. But, at the same time, I know that may be many players would prefer to have something easier to handle, and I've made that set of graphic charts with that goal in mind (you can download it from the post #30 in this thread: I would like you test them, and then let us know your opinion).
But also, in that post, I adress to a link to the 'Warbirds of prey' site where you will find a nice calculator to obtain all relevant data for an accurate manual level bombing, in a more friendly way (for many people, at least) without an E6-B : Ground Speed and bombsight elevation, taking in account OAT and wind.

With OAT in mind, I recently noticed that the Free Air Temperature gauges on the G4M1-11 Betty are bugged. I've reported it to DT so hopefully it will get fixed. Having air temperature gauges that work properly come in quite handy

Yes: I also noticed that during my tests. And I was about to report that issue when I saw it was already reported.
But, until it is fixed, you always can calculate the OAT easily; for 'Betty' it is:

OAT (ºC) = Tmap (ºC) - 0.0065 (ºC/m) * IALT (m)

Anyway, I've said enough...but if you guys would like some help, just let me know.

Well... in these matters is never 'enough', and any help, advise or proposal is always welcome.
