Cadets in level 3 and 4 are required to complete a performance check (PC) in the form of a written test in several aviation subjects. To help cadets prepare for this, we have created an online course for cadets to practice with diagrams, explanations and multiple choice questions.
Level 3s can find this information to help them prepare here: https://versal.com/c/s08cpi/level-3-aviation-review
Level 4 is coming soon! Stay tuned.
