CIRRUS SR20 EVALUATION EXAMS TEST
QUESTIONS AND ANSWERS SURE A+
✔✔What is the basic path of air through the A/C environmental system? -
✔✔ACRONYM : CCREED
C. Compressor
C. Condenser
R. Receiver/Drier
E. Expansion valve
E. Evaporator
D. Distribution manifold
✔✔Through what instruments or receivers does the air data computer get its
information from? - ✔✔It receives data through indications in the pitot static system and
the temperature probes.
✔✔What does LRU stand for? What is an LRU - ✔✔Line Replaceable Unit
It is a piece within the overall ADAHRS system that can be replaced very easily by
installing a new piece that functions the exact same. Almost like very complicated legos.
✔✔Where can a list of all the LRUs in the plane be found? - ✔✔In the G1000 POH.
, ✔✔The magnetic compass attached to the aircraft is suspended in a liquid. What is the
liquid and why is that the liquid that is chosen? - ✔✔It is a kerosene mixture that allows
the compass to spin freely and will have the least amount of reaction to weather.
✔✔What instruments on the PFD are pitot static instruments? - ✔✔The airspeed
indicator, the altimeter, and the vertical speed indicator.
✔✔What instruments on the PFD are gyroscopic/vacuum/electric instruments? - ✔✔The
attitude indicator, heading indicator, the slip skid indicator, turn coordinator.
✔✔There are 3 Distribution Busses in the electrical system. How is the Main distribution
bus 2 powered? What systems are attached to this bus? - ✔✔The main distribution bus
2 receives most of its energy from alternator 2, but it also receives energy from
alternator 1 and battery 1 inadvertently
The main distribution bus 2 also powers...
- Main bus 1
- Main bus 2
- Avionics bus
- Non-essential bus
✔✔There are 3 Distribution Busses in the electrical system. How is the Main distribution
bus 1 powered? What systems are attached to this bus? - ✔✔The main distribution bus
1 receives most of its energy from alternator 1, but it also receives energy from Battery
1 inadvertently
The main distribution bus 1 also powers...
- A/C bus 1
- A/C bus 2
- Main bus 3
- Constant power bus
✔✔There are 3 Distribution Busses in the electrical system. How is the essential
distribution bus powered? What systems are attached to this bus? - ✔✔The essential
distribution bus receives most of its energy from Main distribution bus 2 (which in turn
receives its energy from alternator 2), but it also receives energy from battery 1, battery
2, and Main distribution bus 1 (which in turn receives its energy from alternator 1)
inadvertently.
The essential distribution bus also powers
- Essential bus 1
- Essential bus 2
