In RTL the RTL_ALT will be considered a height above the terrain.  In LAND mode the vehicle will slow to LAND_SPEED 10m above terrain (instead of 10m above home).  This parameter does not affect AUTO and Guided which use a per-command flag to determine if the height is above-home, absolute or above-terrain.
