DB yes I agree on your point about different setups according to the task in hand. For fixed wing, they tend to land at an airfield, all of which are pretty much the same. For oil and gas RW we have offshore ops (flat earth, no need for EGPWS map), ARA where the primary navaid is the radar, onshore ops where EGPWS map can be useful, onshore instrument approaches, and of course visual approaches including night offshore ones. Then there are the different types of departures. But the SOPs should be defined for each of these scenarios so everyone is on the same page - literally!
