steep approaches
There is nothing wrong with learning to do steep approaches. you will need to do them on many jobs. External loads with a long line to small areas is an example.
I have found that a high rate of closure will make a steep approach feel uncomfortable. A slow rate of closure feels more comfortable and allows a more gradual increase in power.
Planning is very important, knowing you have a power margin for the OGE hover is mandatory for a safe comfortable approach.
I have noticed different characteristics between a 212 and412 doing external load work. (OGE hovering) Do the different rotor blade designs effect VRS?
