Recurrent Training
We spend valuable hours and money doing things to our aircraft, including annual inspections, upgrades, and checks. We spend thousands of pounds on preventive maintenance mainly because we don't want to experience a failure in flight. In contrast, as pilots we don't get the same checks and inspections. We allow our competency to degrade until an instructor points out how low our standard has become during a flight review every 24 calendar months.
The only way to avoid becoming a statistic is frequent, recurrent training. Not only is it good sense, the FAA requires it, and so does your insurance. If you hold a pilot certificate, you are required to obtain a flight review (BFR) every 24 calendar months. If you are instrument rated, you are required to obtain a proficiency check (IPC) if you are not current.
