Manitoba Airbrake Practice Exam

If the compressor takes more than two minutes to build air from 85 psi to 100 psi, this is classified as a minor defect. This is because a minor defect is defined as an issue that may impact performance or functionality, but can still be addressed relatively easily and does not significantly impact the overall operation of the machine. Options A, D, and C are incorrect because they do not accurately describe the impact of the compressor taking more than two minutes to build air pressure. A major defect would have a more significant impact on performance and functionality, a critical defect would have a severe impact on the machine's operation, and no defect implies that there is no issue with the compressor taking more than two minutes to build air pressure.
