What is the acceptable suction range for the Cessna 152?

• A. 3.0 - 4.0 in.Hg
• B. 4.0 - 5.0 in.Hg
• C. 4.5 - 5.4 in.Hg
• D. 5.0 - 6.0 in.Hg

Answer: (C)

The acceptable suction range for the Cessna 152, which is typically used to gauge the functionality of the vacuum system that powers instruments such as the artificial horizon and directional gyro, is correctly identified as 4.5 to 5.4 inches of mercury (in.Hg). This range ensures that the vacuum system is operating effectively, providing reliable readings that are crucial for safe flying. Maintaining suction within this specified range is vital for the performance of gyroscopic instruments, as inadequate suction can lead to instrument failures, thereby compromising flight safety. An understanding of this acceptable range is essential for pilots when monitoring their aircraft's systems and ensuring that they are in proper working order before and during flight.
