The carat at centre of this scale indicates your current magnetic heading, in degrees. A heading of 000 corresponds to due north. As your aircraft turns right, the scale will move right to left, and vice versa.
Airspeed
Your airspeed is displayed in the box on the left side of the HUD.
Altitude
The boxed figure to the right of the HUD is your altitude, in feet.
Velocity vector
Indicates the point towards which you are flying. Its position relative to the pitch ladder indicates whether your aircraft is climbing or descending. Level flight is maintained by keeping the velocity vector on the zero pitch line.
Pitch ladder
The pitch ladder is a series of lines, drawn at 5-degree intervals, showing your pitch and roll attitude relative to the ground.
Bank angle scale
Shows your current bank angle (how much you have rolled the wings), and is calibrated at 5, 15, 30 and 45 degrees. Its triangular pointer slides back and forth along the top of the scale to indicate your current degree of roll.
Angle of attack
Also AoA, or alpha.
Your present angle of attack, in degrees.
G load
Indicates current g force (the number of times normal gravity) affecting the aircraft
