So... EIR is not all that practical for helicopters as far as transport from A to B goes, is it? After all, unlike FW, in a helicopter if it starts to close in you can much more easily stop, turn around or land just about anywhere if you need to and it is also safer and more practically to crawl along under it at 500' AGL if the conditions allow it?
But... it would allow for legally engaging in IMC flying for the purpose of up-skilling should one find oneself in IIMC?
