11. For increased engine life, CHT’s should be kept below _____ °F
12. Avoid continuous operations with the fuel flow set between
_____ GPH and _____ GPH with MP above _____ in. Hg. (TN
aircraft only)
13. After completing the cruise checklist, the boost pump should
remain on for _____ min. Why? (SR22TN)
14. (True / False) Leaning the mixture will cause the CHT’s to rise
when operating lean of peak.
15. While climbing at 120 KIAS during a lean of peak climb, the
CHT’s exceed 380° F (SR22TN) or 420° F (SR22T). What is the
appropriate response?
16. What if the CHT’s cool below 380° F (SR22TN) or 420° F
(SR22T) but the climb performance is not acceptable? What is
the appropriate action?
17. After setting cruise power at 85% (2500 RPM / Max MP
(SR22TN) 30.5” (SR22T) / Fuel Flow cyan target) and the CHT’s
remain at 395° F (SR22TN) 425° F (SR22T). What is the correct
action?
18. What is the appropriate course of action in the event of an
unexplained loss of manifold pressure?
19. Shortly after leveling off at 22,000’ you set cruise power, lean the
mixture, and turn your boost pump off. Your engine fails.
What do you do?
Why did the engine fail?
