Answer :
Final answer:
Without context or reference to a specific type of aircraft or equipment, it is impossible to provide the exact rotor brake pressure values required for an engine start. These values are typically found in the equipment’s operating manual or maintenance documentation.
Explanation:
The question pertains to the acceptable pressure ranges for the rotor brake during an engine start in an aircraft or possibly other machinery. Unfortunately, without specific context or reference to a certain type of aircraft or machinery, it is not possible to accurately determine the minimum and maximum rotor brake pressure for engine start. These values can vary significantly depending on the type of aircraft or equipment.
It is recommended to refer to the specific equipment’s operating manual or maintenance documentation for the correct operational parameters. In aviation and engineering, adhering to manufacturer specifications is crucial for the safety and proper functioning of the equipment.
