Do you fly with SOPs? Standard operating procedures (SOPs) are commonly used in the corporate and airline flying world as a way of formalizing the do’s and don’ts of a flight department and making sure every pilot follows the same procedures. I’m generally suspicious of SOPs in life, because they limit your ability to be flexible and react creatively to life’s inevitable changes (we all like our freedom). But when it comes to IFR flying, I believe SOPs are a critical safety tool.
