X-Plane 9 在每次启动的时候都会记录一个log.txt文件，这个文件位于X-plane 9的主程序目录下，在log文件中记录了程序运行时对图形卡硬件的侦测，安装环境和软件版本等信息。如果需要获得支持的话，或者提交bug，那么就需要提供这份记录文件。

下文中的中文内容是增加的说明文字,如果你在运行的时候没有出现任何错误，在日志后面的错误记录部分就没有。

现引用我自己的笔记本上的log.txt文件如下:

log.txt for X-Plane 9.01r1 X-Plane 90101 compiled on Apr 23 2008 22:04:09
这一行记录了主程序运行的版本:主版本号为9，小版本为0.01的第一次发布，程序是在2008年4月23日22：04分编译的。

OK check MemoryLog.txt! I just sent him a dump from This is the dump_mem_stats call from the following code: if(type==t_exit || type == t_alert || recursive_error)
以下为准备导出飞行模型数据的信息和出错的信息
I will dump all the data for the next cycle of X-Plane to the file 'Cycle Dump.txt'.
This will include all the angles of attack, forces, velocities, etc. for this instant in time.
Quit X-Plane and open the file 'Cycle Dump.txt' with a word processor to read the resultant file.
Be sure to turn off text-wrapping in your word processor or allow very wide text area for the file to look right.

OK check MemoryLog.txt! I just sent him a dump from This is the dump_mem_stats call from the following code: if(type==t_exit || type == t_alert || recursive_error)

The aircraft must now be in trimmed, level flight. It must be in trimmed, level, un-accelerated flight BEFORE you select this menu-option.
The controls should be centered, with the exception of any trim needed to hold level, un-accelerated flight. The autopilot MAY be on, since it will not have time to affect the test results.
I shall now instantly displace the nose exactly 1 degree, and look at the instantaneous acceleration back to trim of the craft, before the autopilot can respond.
By looking at that acceleration, I will know the stability derivative. I will output my findings to the end of the text file 'Cycle Dump.txt' for you to see.
