Thanks rudestuff. What I do not understand is that point to point is geometric path as mentioned in FCOM, and does not specify if it only applied to altitude constraints including at or at or below altitudes. In the example I wrote above, I was descending from FL240 to first waypoint A, was the FMC actually following the geometric path?
In other words, can point to point be applied from CRZ level to waypoint A in this case?
What about the ABOVE altitude restrictions? They are not taken into account for building up Geometric PATH?
