So im looking to start my first few flights on vatsim but i wanted to start with a plane that im comfortable with and was hoping to start with the cirrus vision but when i look at the simbrief stuff i dont see it and dont know if i would be able to use it. If i can use it. Also what does it mean by true speed when im going to file a flight plan? Thank you
The only thing I believe SimBrief looks at when selecting a aircraft is the performance profiles for more accurate fuel burn, efficient altitudes, etc...I would personally just select a citation or something similar, what you don't want to do is select a C172 or other small prop as it may assign you a low altitude prop only route. Once you let SimBrief make a FP for you, on the bottom of the page there are multiple formats to download the FP, scroll down to select your X-Plane version, there is a ? next to them for instructions to install also.
Don't worry to much about TAS, again this is used for fuel planning purposes in SimBrief. For VATSIM purposes its there basically for added realism, nothing practical comes out of filing it the proper way.
