There are a number of times a pilot may be required to undergo recurrent instrument training. Many professional pilots, such as commercial pilots, instructors and others, are required to keep their instrument rating current by attending training and simulator checks once or twice a year. Non-professional pilots are also usually required to undergo recurrent training of their skills by their insurance companies.
The first step to recurrent training is completing an instrument proficiency check (IPC) every six months, through which a pilot can test his level and ability and determine if he needs or desires more training. This test will challenge the pilot's current skills and ensure that they are up-to-date. A pilot who performs poorly during this check may be required to undergo further training.
The IPC must be administered by an instrument flight instructor who holds the appropriate instructor rating or a designated pilot examiner or FAA examiner. If a pilot requires additional recurrent training, she can enlist an instructor qualified to give instrument training.
