TRADITIONAL POINT-TO-POINT NAVIGATION
The following steps (Figure 25) are used to accomplish the point-to-point procedure: First, tune and
identify the appropriate TACAN or VOR/DME equipped station. The aircraft HSI display will function as a
plotting board. Place the station at the center of the compass rose and picture the fix with the greater
distance on its radial at the edge of the HSI display compass rose. The HSI display scale and the scale
you use for a point-to-point calculation do not have to be the same. Visualize the fix with the lesser
distance (determined by the previous step) placed at a proportional distance from the center of the HSI
display on its radial. The aircraft is placed on the tail side of the radial the aircraft is on. Where on the
radial is determined by which fix is greater. If the aircraft is further away from the station than the point-to-
point target fix, then the aircraft fix will be located where the tail of the bearing pointer crosses the
compass card. If closer, then the aircraft is located at a proportional point along the tail of the bearing
pointer. Once the fixes are determined, connect them with an imaginary line or with the aid of a straight
instrument such as a pencil. Move the line to the center of the HSI display, paralleling the original
imaginary line, and read the course to the target fix where the line intersects the outside edge of the
compass rose. Turn the aircraft to the new course and apply a WCH, if known. Repeat the point-to-point
procedure periodically en route and make corrections to the target fix as needed.
