Effective Radius Method.
Ceiling | Refraction will be ignored if object altitude is higher than the ceiling. Uses Distance Dimension. |
EffRad | Effective radius used to compute refracted elevation. Dimensionless. |
MaxTargetAltitude | Maximum altitude of target for which the refraction will be computed unless extrapolation is used. Uses Distance Dimension. |
UseExtrapolation | Flag controls whether extrapolation is used past the maximum target altitude. |
