Section 14. Primary Flight Display (PFD)
Pitch
The ADI is accurate for +/- 90˚ of pitch. The pitch display remains static over the
range of 23˚ nose up to 23˚ nose down. Beyond +/- 23˚ a portion of the sky or a
portion of the ground are always visible. At extreme pitch angles, angles greater
than 50˚ pitch up and 30˚ nose down, a series of white chevrons point towards
the horizon.
The pitch scale is displayed has horizontal labeled lines at 10˚, 20˚, 30˚, 40˚, 50˚,
and 70˚, with unlabeled lines every 5˚. The right and left side of the larger
increments have tick marks pointing either up or down towards the horizon. At
90˚ of pitch there is a small circular ring.
Roll
The ADI is accurate for +/- 180˚ of roll. The roll scale is displayed with black
triangles at black triangles at 0˚, 45˚ left, and 45˚ right; large tick marks at 30˚ and
60˚ right and left and smaller tick marks at 10˚ and 20˚ right and left. Roll angle is
displayed by a white triangular roll pointer that remains parallel with the airplane
symbol (fixed at the top of the ADI).
NOTE:
The roll scale remains fixed at the top of the ADI while the roll pointer and the
airplane symbol roll in parallel with the airplane.
