If you received no response from ATC after your waiting time, what should you do next?

When you receive no response from ATC after your waiting time, it is essential to call ATC to inquire about your clearance. This approach allows you to gather necessary information and ensures that you remain within the confines of regulations and safety guidelines. Communication with ATC is crucial for maintaining situational awareness and ensuring that all aircraft operations are conducted safely.

Initiating takeoff without clearance would violate FAA regulations and could potentially lead to unsafe situations, such as conflicts with other aircraft that may be taking off or landing. Continuing to hold position without further inquiry fails to address the lack of communication, which may lead to delays or misunderstandings. Performing a safety check, while important in other circumstances, does not resolve the immediate issue of not having clearance or understanding your current instructions from ATC.

By contacting ATC to inquire about your status, you demonstrate a proactive approach to operational safety and compliance with air traffic control protocols, making it the most appropriate course of action in this scenario.
