Paco,
You're quite correct that the question was not framed in a way that an answer could easily be provided.
After exchanging a series of PMs with 'rvl', it would appear that her question was about operating from a 'congested hostile environment' and therefore related to the 'helipad' procedure.
As I always point out, on a runway, the clear area CAT A procedure provides little that PC2 could not provide - PC1 has to be achieved by 200ft in either case and the take-off mass is almost always related to the second segment climb (which starts at that level).
