I use the term somewhat loosely. Some of you may not agree as to whether this label is applicable to all the examples given below. However, it can be agreed that some operations, require a greater level of expertise, and therefore may not be appropriate for a low-time pilot, while other tasks can be conducted with a high degree of safety by most knowledgeable pilots. All of these conditions work to improve safety by promoting peak performance from the pilot while minimizing fatigue induced hazards. All companies have a requirement for some internal flying that may not involve passengers, or a paying customer, and therefore might be suitable for time-building a junior pilot.
Some examples are ferry flights, and test flights following maintenance.
Some operators may also be able to use the pilots in areas where the customer requirements are more flexible, such as tourist flights, sightseeing or photography trips. Also, many helicopter companies are becoming very innovative and moving away from strictly charter work to conduct business operations that require helicopter support on their own. For this type of operation, they have the flexibility to use whatever pilot they feel competent to do the job. One example of this, is a company that owns its own timber sales, and uses its aircraft to log them. This sort of operation also often allows the set up of a monitored flight training program, where a junior pilot is able to fly with a training pilot while dropping off the in-house fallers, or collecting chokers, etc.
