I SHOULD know the answer to this, but it isn't fluent in my knowledge, so I'd like to learn more. There are 2 airspeeds displayed in IL-2. In the cockpit and with the speedbar selected you get one speed. With the cockpit off gauges you get a different, faster speed.

So, what are the two, and what is the difference?

Thanks in advance

The gauges in the cockpit and, presumably, the speedbar show your indicated airspeed. The cockpit off gauges (If I am not mistaken - I never play with cockpit off.) show your true airspeed, that is, the airspeed of your aircraft relative to the ground.
Indicated airspeed is affected by pressure - and thus your height ASL.

Hope that helped somewhat. If not, I can always try to read up a bit more and relay the info to you http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

I know TAS and IAS, but which one is which and what is the difference between them?

I know, I'm pathetic. You may shoot me down at will.

indicated is slower

TAS is relative to the ground & not just how fast your slicing thru the air

TAS is a faster speed

IAS is what the speedbar states

TAS is what the no-cockpit view says

TAS is, as described, the true speed of the aircraft relative to the ground. IAS is the airspeed indicated by the measurement instruments, in planes without fancy modern instrumentation this is what the airspeed indicator shows. The method of measuring the airspeed uses the outside air, so depending on atmospheric conditions and altitude it is different. There is a PDF with a table for IAS/TAS conversion on CD2 in the folder MANUAL. It's useful for the bombsights.

So, If I am being chased and want to go "faster" I would make sure that I am not in the cockpit view mode then........ http://ubbxforums.ubi.com/images/smiley/16x16_smiley-very-happy.gif
