To ensure safety, why is it important to adjust MAD based on altitude?

Adjusting the Maximum Allowable Deviation (MAD) based on altitude is crucial for mitigating risks associated with environmental factors. At higher altitudes, the density of air decreases, which can affect various aspects of crane operation, such as engine performance, load stability, and the ability of hydraulic systems to function effectively. These environmental changes may lead to unsafe operating conditions if not accounted for, increasing the risk of accidents or equipment failure.

By adjusting MAD with altitude in mind, operators can ensure that safety measures are adequate for the specific conditions they face, ultimately protecting both personnel and equipment. It reinforces the importance of recognizing how environmental factors impact operations and adjusting parameters accordingly to maintain a safe working environment.
