My bomber would not calibrate in FSO, this is the second time it has happened. Instead of getting a good calibration in the bomb sight, it gives me a bad speed and alt indication. Along with this, the bomb sight runs east to west instead of north south when in calibrated mode. I know manual calibration is needed, but doesn't seem to be affective. Everyone else in the mission was able to drop, but i did have someone say it had happened to them before too. Any advice or direction to fix this would be greatly appreciated.
