I'm not sure at the moment that it's entirely clear what "something like this" is at the moment. If it's common helicopter operating practice, then you're absolutely right. If it's aircraft design approval legalities, you probably aren't - and if it's helicopter aerodynamics, then I can certainly hold my own but if it was the core of a task, I'd certainly defer to somebody much more experienced (as I did quite recently in fact over something related to a helicopter accident issue which related to blade dynamics - the chap who originally taught me my helicopter aerodynamics had a lot of fun with the task I believe.)
