Is the data you are quoting from "approved" or "manufacturers data". There is a big difference. Is this approved flight manual info?
This procedure in the A109E involves a back up with the pad in site to 85' to TDP. Failure prior to TDP is to aim the helicopter at the pad and defend your rotor RPM. At high weights you will see a chevron in the AI at about 15 degrees nose down.
After TDP you may of course descend to within 35' of the departure height i.e. lose 50' getting to VTOSS.
Of course the 109 is a Part 27 aircraft and hence is only Cat A "similar" performance. Cat A only applies to Part 29 Transport Category aircraft.
I don't believe you are reading all the correct data that is available.
Fill us in on the rest.
