Chase View projection: Perspective makes distant objects appear smaller. Orthographic keeps the scale uniform with distance. Press P to toggle.
Show lift in blue, drag in red, and relative wind in black. Enabling this selects Chase View.
Show flight instruments, pitch ladder and HUD cues. Press H to toggle.
Fine square surface grid, each square colored from its terrain center and shaded darker, below 2,000 ft above ground. Uncheck to restore the normal terrain view.
Level-flight drag and thrust available at current altitude, with live Mach markers. Both use lbf; amber thrust scales with throttle.
Whole-aircraft drag polar with a live marker for the current flight condition.
Ps map is precomputed at 1 g and maximum thrust for the Initial Conditions fuel and payload. The dot tracks Mach and altitude.
Gun funnel showing the positions of previously fired bullets at the represented ranges. Target wingspan sets the funnel width.
Predicted bomb impact using gravity and drag. CCIP and STRAFE are mutually exclusive.
Predicted bullet impact using gravity. The clockwise range arc represents slant range, with a full circle equal to 6,000 ft.
