Hello, i am faced with a peculiar problem,i use FS2002 and have beeninstalling mesh files lately ,the problem is that when i start my flights on a selected runway my headings are off about 30 degreesto the right EG if i am on rwy16 my heading show 190 deg and as i go further east the deviation increases to even 40-50 degreesi need some help in getting this problem solved ,is there any simple enough way to correct this problem Dee

Are you indicating it is the mesh or that the heading indicator is reading 30deg error.If it is the heading indicator, select Aircraft, Realism, and deselect Gyro Drift. Exit the flight simulator, then restart and see if the problem is corrected.W. Sieffert
