(1) Same as we do in fixed wing when we land at a private site - any clearly identifiable name: Ardrossan Beach, Compleat Angler...
(2) Flight ops is an abbreviation of flight operations, so more correctly is written "flight op's" since the apostrophe replaces the missing letters. Technically speaking, the norm is wrong, and "flight op's" is right. (Okay, lasor's is definitely wrong however.)
(3) Many helicopters are on Permits to Fly - for example ex-military Scouts, or homebuilt Rotorways. A Permit doesn't permit night flying, hence the aircraft isn't rated for night.
