>You are correct. CI modelling was introduced with the 800/900>add-on.Ah, right. The printed manual with the Aerosoft CD for the 800/900 says it isn't but there was obviously a later change. So how do purchasers of the CD have it?Iain Smith

Iain,I honestly don't know. If you have the CD version the easiest way to find out would be to program the FMC with some various CIs and you should see differences in the calculated speeds in CLB, CRZ and DES.Hope it helps,

Even though the manual says it's not modelled, it does explain what CI is and it says the values entered are from 0 to 1000. I entered 650 for my test and was told "invalid entry". So my tests were 10 and 100. Can you tell me, please, what the correct range is?ThanksIain Smith

Iain,On the NG the CI range should be 0 to 500.Hope it helps,
