Figure 53. Two ways of visualizing Patch Test lines to be done

To do the roll test (per Figure 53)

In a flat, deep section of the Patch Test area, run line A to B and then
B to A at a constant survey speed (for example, 4 knots).

To do the latency test (per Figure 53)

Run line C to D slowly (2 knots) and then quickly (6 knots). Both runs
must be done in the same direction.

To do the pitch test (per Figure 53)

Run line C to D and then D to C, both at a constant survey speed.

To do the yaw test (per Figure 53)

Run line C to D and then E to F, both at a constant survey speed. As
noted in the figure, lines CD and EF are parallel. Also, the lines
should be separated by a factor of 1.5 to 2 times your water depth in
order to have the outer beams of each swath overlap one another.
