Pilots should report how many hours before international flights at the assigned location prior to the pilot's first scheduled flying duty?

Pilots should report 1.5 hours before international flights at the assigned location prior to the first scheduled flying duty to ensure all necessary procedures and protocols are completed before takeoff. This timeframe allows for adequate preparation, including pre-flight checks, briefings, and coordination with ground personnel. Reporting earlier than the specified time also helps to accommodate any unforeseen delays or additional requirements that may arise. This practice is essential for maintaining safety and compliance with international aviation regulations. By adhering to this reporting time, pilots can ensure they are fully prepared and focused for their duties, reinforcing the overall safety and efficiency of flight operations.
