Manitoba Airbrake Practice Exam

Older air systems may operate with lower pressure settings.

1. True

2. False

3. Only in certain conditions

4. None of the above

The correct answer is: True

Air systems, specifically air compressors, are designed to operate at certain pressure settings to ensure efficient and safe functioning. As air compressors age, their internal components can start to wear out, causing them to operate at lower pressure settings than initially intended. This can lead to decreased performance and potential safety hazards. Hence, it is true that older air systems may operate with lower pressure settings. Option B is incorrect because it is a blanket statement that does not take into account the age of the air system. Option C is incorrect because it limits the answer to certain conditions, which is not always the case. Option D is incorrect because it negates the possibility of older air systems having lower pressure settings.
