Velocity Vector
4.
Caged velocity vector is derived from the
Sg 4, fr 5
intersection of two lines
a.
LINE-1: Plotted perpendicular to the
pitch ladder's Horizontal Flight Lines,
originating from a point on the HUD
centerline that equals the degrees of
AOA (True) degrees measured from
the invisible HUD waterline reference

VELOCITY VECTORS
b.
LINE-2: Plotted parallel to the pitch
ladder's Horizontal Flight Lines from
the Ghost (True) velocity vector plot
point
LESSON NOTES
Only the Ghost/True velocity vector (unlimited) can be
referenced to correctly observe actual aircraft
movement in relationship to terrain and objects seen
through the HUD. The Caged velocity vector is
artificially (arithmetically) repositioned to keep it
oriented near the center of the HUD display, and to
make that vector less likely to become limited. But,
once again, the Caged velocity vector does not indicate
actual aircraft vector movements in relationship to
terrain and objects viewed through the HUD.
5.
When the Ghost (True) velocity vector
Sg 4, fr 6
becomes periphery limited it flashes at
3.125 Hz
