Hey Blade
The portion of the approach from LDP to the pad Cat A for the 412 shows a 30 degree approach angle.
Don't have the supplement at home but I will check it at work tomorrow to confirm.
Yes it is very steep.

Passing thru 100' at 50 knots to a helipad seems pretty fast to me and you only need 10 degrees nose up to slow her down.....she must be pretty nose heavy.
