RE: no week point tail rotor.
Confined "unreccied" LS's are not a problem on Trinity ops as all the sites are known and loved.
The scenario is extreme turbulence operating in winds of up to 45-55 knots in exposed coastal rock stations, and underslinging at MAUW out of wind in gusty, turbulent conditions.
Add in a moving deck and the operation is rather different to Police/Air Ambulance.
