T-45C TS & ADV CO-09; IUT CO-05
Velocity Vector
B. Limited velocity vector
Sg 3, fr 3
1.
Definition of LIMITED: When the velocity
vector plot falls outside the HUD velocity
vector display limits
2.
Characteristics
a.
Velocity vector is positioned on the
VERTICALLY LIMITED
VELOCITY VECTOR
velocity vector display limit periphery
b.
Velocity vector flashes at a 3.125 Hz
rate
NOTE: A flashing velocity vector
indicates that the HUD climb/dive pitch
reference at the waterline may have
become invalid because of HUD pitch
ladder rotation around the velocity
vector. Also, it alerts the pilot that his
HUD velocity vector position is no
longer accurately positioned with
respect to objects outside the cockpit
viewed through the HUD.
c.
HUD Pitch ladder rotates, as required
Sg 3, fr 4
depending upon degrees of AOA,
around a vertically limited velocity
vector
