Simulation Test of the Arcata, California, Diamond Runway Centerline
The guidance value of the Arcata diamond runway centerline paint markings was tested by comparison with the U. S. standard centerline markings in the Dalto/P-3 visual simulation facility. Twenty experienced pilots participated in the testing. Results generally favored the U. S. standard centerline consisting of a 3-foot-wide interrupted stripe with l20-foot painted length and 80-foot gaps, as opposed to the 1O-foot maximum width diamonds with 75-foot length and spacing. The only exception was that the diamonds were seen farther away prior to touchdown, a result that is attributed to the one-third larger total painted area.
