Westhawk,
I'm not rated on the HS, but sounds to me that you should raise V1/Vr/V2 figures computed from your tables so as to comply with Vmcg/Vmca criteria.
Doing this you may end up with a reduced Max allowable TOW and/or realize your HS is so performance limited that you may not be legal to operate from particular fields under such and such conditions.
And definately, the 800XP complies with FAR/JAR25 requirements, but once again cannot fly to/from every airfields under all circumstances.
