What does a helicopter pilot do?
With a PPL(H), a pilot may fly recreationally, and passengers may come along if the costs are shared equally, but accepting money or services is not allowed. A CPL(H) allows a pilot to fly for pay for a company under the company's regulations. For your own commercial work, an air operator certificate is required.
A helicopter pilot can work in a Search and Rescue (SAR) unit, such as the Bristow SAR unit in the Gulf of Mexico. These units operate as a subscription service for offshore companies and use helicopters such as the S92A, AW139 (both with winch and rescue swimmer) and S76 (medevac only). A pilot is called out on average 3 to 4 times per 14-day shift and flies at least one training flight with three offshore landings with night vision goggles.13
