Roll Indicator

Bank Attitude Indicator (BAI) 10 20 30 60 (Attitude Director Indicator)

Roll Indicator 10 20 30 45

Depending on the current HUD mode, one of two roll indicators will be displayed - the BAI (Bank Attitude Indicator) is a small scale which rotates around the flight path marker, showing the current bank angle. 

The roll indicator is located at the bottom of the HUD, and looks like a larger mirror image of the BAI. 

The roll indicator has tick marks at 10, 20, 30, and 45 degrees, while the BAI has tick marks at 10, 20, 30, and 60 degrees.

DED

Set DED (Data Entry Display) Data Switch FWD, which will allow data from the DED to be visible on the HUD

TTL / TD

When the locked target is outside the HUD field on view, a Target Locator Line (TLL) extends from the Gun Cross and points directly at the target. The Relative Angle is displayed next to the Gun Cross showing the number of degrees in tens between the cross and the target. Otherwise a Target Designation (TD) Box is shown
