IAS/TAS conversion Calculators and Tables. Presented with altitudes in Feet and Meters.By Colonel Sanders LiteTo report bugs and suggestions, contact me through the IL2PF forums.Please be sure to include the parameters used if it's a bug. A track would be nice too if it's a bomber thing.

Order of charts:A Bunch of usefull calculators.IAS to TAS Table; Altitude Feet. IAS to TAS Table; Altitude Meters.TAS to IAS Table; Altitude Feet. TAS to IAS Table; Altitude Meters.IAS to TAS (B-25 Bug) Table; Altitude Feet.

Why so many charts?Simple really, each chart has a different use.The TAS to IAS charts are useful for when you have to fly a certain course speed and TAS is the only thing given. In the FMB, KPH TAS is the only unit used so it is certainly useful to mission builders as well. The IAS to TAS charts are also useful to bomber pilots who must know their TAS to bomb accurately. The Game Uses 2 different standards of altitude measure so that doubles the amount of charts needed. The calculators can't be printed really so they can't be used on the fly in mission.

Notes:It doesn't matter what unit is used for speed. As long as the IAS/TAS units are the same, the formula works as it is a ratio.It is important however, that you use the correct chart for the altitude measurements.To use the calculators, Change the numbers in the GREEN boxes and press enter.The Red Boxes will Show the result.These speeds are derived from a simple formula and aren't 100% accurate. They'll be close enough for all practical purposes for the most part.Since they don't take into account atmospheric effects like humidity etc, the results may vary slightly on different maps.Since the exact formulae and variables used in the game are unknown to me, these are as close as I can get without more trial and error.Please bring up any values you know are more correct universally.With the B-25 sight bug stuff, only use them in conjunction with that plane's sights.

Special Thanks to:MaxMhz for hosting this file.Platypus_1.JaVA For letting me know about the B-25 bug.

Printing:The Charts Are really meant to be printed 1 to a page. Use "Set print area" and Scale to fit to do this.The final decision on how to print is left up to the user however.

Note: The below calculator is to be used with the B-25's bomb sight bug. ONLY use it in conjunction with that sight.The problem is supposedly that the B-25's bomb sight is in knots while it's speed gauge is in mph. All thiscalculator does is convert your MPH IAS to a Knots TAS.Also, Please let me know if it's ever fixed in order that this can be removed.

Note: The below table is to be used with the B-25's bomb sight bug. ONLY use it in conjunction with that sight.The problem is supposedly that the B-25's bomb sight is in knots while it's speed gauge is in mph. All this tabledoes is convert your MPH IAS to a Knots TAS.Also, Please let me know if it's ever fixed in order that this can be removed.

Please be sure to include the parameters used if it's a bug. A track would be nice too if it's a bomber thing.

The TAS to IAS charts are useful for when you have to fly a certain course speed and TAS is the only thing given. In the FMB, KPH TAS is the only unit used so it is certainly useful to mission builders as well. The IAS to TAS charts are also useful to bomber pilots who must know their TAS to bomb accurately. The Game Uses 2 different standards of altitude measure so that doubles the amount of charts needed. The calculators can't be printed really so they can't be used on the

It doesn't matter what unit is used for speed. As long as the IAS/TAS units are the same, the formula works as it is a ratio.

These speeds are derived from a simple formula and aren't 100% accurate. They'll be close enough for all practical purposes for the most part.Since they don't take into account atmospheric effects like humidity etc, the results may vary slightly on different maps.Since the exact formulae and variables used in the game are unknown to me, these are as close as I can get without more trial and error.

The Charts Are really meant to be printed 1 to a page. Use "Set print area" and Scale to fit to do this.
