Interesting Thread.
My old and wise instructor told me that the H/V curve in a CAT A certified machine was only associated with the clear area T/O and landing profiles.
It is not relevant to VTOL procedures for obvious reasons.
And applys to all CAT B operations. It applys to clear area PC 1 and PC2 as it’s only the TDP and LDP points that change.
I am sure I will get some feed back on these thoughts.
