What should you do upon arrival at a clearance limit if no further instructions are provided?

When you arrive at a clearance limit and no further instructions are given, the appropriate action is to request further clearance and hold. This ensures that you remain compliant with air traffic control (ATC) procedures and maintain safety in the airspace. Holding at a clearance limit allows you to await further instructions from ATC, who may then provide you with a clearance to continue on your flight plan or give you directions to another destination.

This protocol is critical for several reasons. It helps to maintain an orderly flow of air traffic, especially in busy airspaces, and prevents potential conflicts with other aircraft. By actively seeking further clearance, you demonstrate responsibility and adherence to aviation regulations, ensuring the safety of both your aircraft and others around you. In aviation practice, holding at a clearance limit is a standard procedure when awaiting additional instructions, making it the correct choice in this scenario.
