I have been flying the JROLLON CRJ200 for a while now. I have made MANY attempts at understanding the TRIM table that he has made. I have come across this spreadsheet that calculates it for you that was approved by for use by JROLLON. For example: I have a planned flight from KATL to KIAD (attached is the .pdf file for this flight) After all is calculated, the LITOW is not within range. It brings me to a LITOW of 12. This is not possible when trying to find on the provided chart for a MAC%. This has been a CONTINUOUS problems since I have purchased the CRJ2. Every flight I conduct, this SAME situation arrises. I have been assured by Mr. Rollon before that it is because X-Plane does not simulate the COG correctly... but that does not make sense to me because the chart by itself is not working. I have, before and currently, just used the charts provided with the aircraft file manually and it does the SAME thing.. So that is why i am now posting here... does anyone else have this problem? I believe i am doing something wrong.. but i just don't know what it is. Any help would be GREATLY appreciated! Also, I would like to have a chart that provides the Optimum Flight Level for a given gross weight... an example for what i am looking for is also attached. It is a simple B787 Long Range Cruise Control chart.
