HE and LE definitions specify that HE stands for what while LE stands for what?

• A. HE = highest point; LE = lowest point
• B. HE = horizontal elevation; LE = lowest elevation
• C. HE = height estimate; LE = level elevation
• D. HE = high end; LE = low end

Answer: (A)

HE and LE denote the extreme elevations within the landing zone. HE stands for the highest point, and LE stands for the lowest point. This distinction is used because knowing the top and bottom elevations sets the vertical boundaries you must account for when evaluating slope, rotor clearance, and obstacle risk during landing or pickup operations. The other interpretations—such as horizontal elevation, height estimate, level elevation, or generic “high end/low end”—do not reflect the standard definitions and wouldn’t provide a consistent basis for planning and safety checks.
