Which elevations are used to compute the vertical distance (VD) when determining LZ slope?

Explanation:
The key idea is that the vertical distance used for LZ slope is the change in ground height across the landing zone. You determine it by taking the highest point within the LZ and the lowest point within the LZ, then subtracting the lowest from the highest. This highest-elevation minus lowest-elevation value is the vertical distance you use (VD). Once you have VD, you pair it with the horizontal distance across the LZ to compute slope (VD divided by HD, times 100 for a percent). So the elevations you use are the highest elevation and the lowest elevation within the LZ.
