Familiarization Flight Procedures
T-45C TS, ADV & IUT FamFP-01
a.
Velocity vector indicates actual aircraft
Sg 4, fr 24
flight path; visually and in degrees of
pitch
HUD Characteristics
* Significant items
b.
Waterline reference (line) indicates
aircraft pitch attitude
- The uncaged velocity vector
becomes "limited" at AOA
c.
Difference between waterline and
angles that depress the vector
11.13 (or more) degrees
velocity vector degree positions indi-
elevation below the aircraft
cates approximate AOA in degrees
waterline
d.
Vertically limited velocity vector flashes
- When a velocity vector is
and causes the pitch ladder to rotate
"limited," the HUD pitch ladder
will then rotate around the
about it
"limited" vector to show
correct velocity vector angles;
e.
Velocity vector becomes limited at
however, aircraft climb/dive
11.13 degrees (positive AOA)
pitch angles become errone-
ous
(1) Flashes at bottom of the HUD
- When "limited," the velocity
display
vector flashes to warn that the
HUD is not accurately indicat-
(a) 11.3 degrees is the degrees
ing the aircraft climb/dive
difference between a vertically
angle
limited velocity vector and the
waterline
