Final answer:
When unfamiliar with a taxi clearance, a pilot should ask the controller for clarification or progressive taxi instructions to ensure safety and compliance.
Step-by-step explanation:
If you are unfamiliar with the assigned taxi clearance, it is important to ask the controller for clarification or progressive taxi instruction. This ensures safety on the airfield and compliance with air traffic control. The correct course of action is to communicate with the controller, stating that you are unfamiliar, and requesting either a detailed explanation of the clearance or step-by-step guidance. Progressive taxi instructions are given to guide a pilot along the taxi routes when the pilot is not familiar with the airport or when visibility conditions are poor.
In the aviation industry, effective communication between pilots and air traffic controllers is paramount. Seeking clarification when faced with unfamiliar taxi clearances demonstrates a commitment to safety and adherence to operational protocols, contributing to the overall safety and efficiency of ground movements at airports.
