Closed Book NATOPS



In addition to taking the open book exam you will want to read your NATOPS thoroughly and pay particular attention to Chapters 4, 7, and 11.

Much of the actual test is EP's and limitations. You might think "hey I know my EP's and limitations" but do you? What is your external load limitation? What are the indications of sprag clutch slippage? Seizure? Get into the numbers and the indications and you should be good to go.
