The heading on the attitude gyro on the A4/F4 called the AJB-3/AJB-7 respectively works exactly backwards. For example, turning left from east to north, you should see the headings move left to right as they decrease from 090 to 360.
First sim that i have seen attempt to model this amazing instrument, when modeled correctly, will enable the pilot to fly complete aerobatics without outside reference. That is why they should be fixed ASAP.
