True Altitude?

[Soldier_Fortune]

Good morning.

I've made and attached below a set of 4 printable Manual Targeting Charts. The Readme into the .zip file explains how to use them.

The cons of these charts: they must be used together with an E6-B Flight Computer.
The pros: they are printable and can be used in-flight.

It is very easy to learn how to use an E6-B, and really it is a cool and useful tool... specially if you like to fly without waipoints.
IMHO, Il2 linked to a combo of printed maps and charts, an E6-B, a plotter and a pencil, is the more realistic and historical approximation to the work that made the airmen in the 40's... for pre-flight planning and navigation, at least.
The price of an E6-B ranges from about 15 up to 50 U$D, regarding of its material (metal, plastic fiber or paperboard) and its trademark, and it can be purchased in aviation stores and online.

But perhaps many players would prefere a "digital age" solution instead of the proposed "old analog age" method.
Yesterday I found this thread in the Warbirds of Prey forum, containing a very complete calculator for manual targeting. It does all what we were talking about in this treath in a very fast way.
I used it to compare the BS Elevation Angles obtained with my charts against those obtained with this calculator: within the desirable accuracy limits, the differences are negligible.

The pros of this calculator: very easy to use and the user doesn't need to learn nothing.
The cons: it is an online calculator and therefore it can not be used inflight; the player must pause and minimize the game and then open the calculator.

Well... Now the level bombing fans have two different methods to perform manual targetings. Both are very accurate and replace the old and obsolete charts and tables. So the choice depends on the tastes of each player.
