What does the acronym RALS stand for in the 90-degree offset navigation method?

• A. Right Add 90 Degrees; Left Subtract 90 Degrees
• B. Rotate And Locate System
• C. Right Angles, Left Signals
• D. Return And Log Steps

Answer: (A)

RALS is a mnemonic used in 90-degree offset navigation. It tells you how to alter your bearing to create a perpendicular offset from your baseline course: when offsetting to the right, add 90 degrees; when offsetting to the left, subtract 90 degrees. This simple rule produces two perpendicular directions to your travel line, allowing you to locate a point by offset and triangulate position. The other options do not reflect the standard directional adjustment required by this method and therefore don’t apply.
