SR-Series Workbook ___________________________________________________
9.2 Turbo System SR22 TN and SR22T
Before conducting training you will need to be familiar with the following:

Limitations of the system

Basic operating principles of turbo-normalizing and turbocharged
systems
Note: The answers to these questions can be found in your supplement
and the appropriate turbo presentation found in the Cirrus Training
Portal. For SR22T aircraft refer to section 7 of your POH
1. What is the purpose of the intercooler/aftercooler?
2. What could cause an over-boost situation?
3. What is the maximum Turbo Inlet Temperature (TIT)?
4. What is the maximum certification altitude?
5. (True / False) A closed wastegate sends more exhaust through
the turbo.
6. (True / False) An open wastegate allows exhaust to bypass the
turbo and be dumped overboard.
7. Does the turbo have a critical altitude?
8. While the engine is idling on the ground, is the wastegate open
or closed? Why?
9. (True / False) The mixture should be leaned for take off at higher
density altitudes to compensate for the decreased pressure.
As the aircraft climbs to 25,000' from SL, what happens to the
10.
wastegate? Will the wastegate be fully closed at 25,000' MSL?
