Over-Talk, you certainly do! If, that is, you mean to say that the exemption for pre-92 aircraft is ONLY applicable to sightseeing operations.
The oft-maligned (at least on this forum) HAC was instrumental in having TC's legal beagles reverse their previous position regarding the use of said rear-seat shoulder harnesses to the current interpretation that, IF INSTALLED, they are required to be worn. Ergo, many heli-skiing operations now remove said harnesses for the skiing season, replacing them for summer fire-fighting ops, as demanded by the provinces.
Furthermore, I don't expect anything approaching empathy from you, but many helicrew personnel will understand that, given the economics inherent in having to cut time (fares) to the bone so the customers of tour buses are willing to drop by and provide operators with business, every minute and staff position saved is critical in making helitour opelrations viable. Said viability means jobs, and a stronger industry. Yes, there are tradeoffs none of us would sooner see, but we don't want to see mothballed machiner, either.
