In this particular subject a great deal of detail is provided on the amount of regulations and procedures that the pilot and crew is required to be familiar with before and during the flight. The fact that the pass rate in Operational Procedures is said to be ‘normal’ is out of whack with most candidates‟ lived experience; it is the experience where, no matter how hard you strive to understand the course material and rehearse the past questions, during the examination a completely new and unprecedented question may arise that most of the competent pilots would not be able to answer without the assistance of an ops manual or EASA standards – which in practice is what people do. The only possible advice is: try your best and do not let it get you down, the statistics are on your side!
