To your point regarding IFR infrastructure, SAS, you raise a particularly relevant aspect of this tragic event. The aircraft technology to fly precise separate helicopter routes and approaches to a GPS/inertial hover at a preselected point already exists and is in production. ( this isn’t a proposal to enable/approve approaches to school parking lots by the way ). In the case at hand, if the infrastructure existed,an IFR route to Camarillo,for example would have removed the weather factors. Helicopter VFR routes exist in two large cities and work. The air vehicles, flight control technology, navigation technology, and precise/automated aircraft position technology are all positioned to fly helicopter IFR routes. The challenge is deciding to do it.
