212man,
Thanks for that. Had no idea how to research my question but your info led to this:

So, I suppose that local terrain and other obstructions will be variable and affect just how low/near one can go in relation to the helipad. And these are published approaches that are in a database ?
Also, what does the cockpit instrumentation depicting these approaches look like ? Something similar to what the fixed-wing world knows as an FMS display ?
