eeyou Posted November 13, 2022 Share Posted November 13, 2022 Hi. Would appreciate some assistance regarding cost index value & OFP generated through simbrief(maybe dumb question and missing obvious, but i couldn't find anything useful in google myself). Oftentimes (like with A320, 737) simbrief calculates CI for you, so all you need is to take that value from the generated OFP and put it into FMS page. However, with the provided by iniBuilds simbrief aircraft profile, OFP returns Mach number instead, so logic mentioned above, as I see it, isn't applicable. How does one figure what CI value to put into INIT A page in this case? Thanks! Link to comment Share on other sites More sharing options...
Deleted Account Posted November 13, 2022 Share Posted November 13, 2022 SimBrief doesn´t support cost index for the A310. However a cost index between 45 and 75 will give you a cruise speed of M.78 - M.80 2 1 Link to comment Share on other sites More sharing options...
