Selective Calling System(SELCAL)
Definition
A system that alerts a specific aircraft crew when ATC needs to communicate over HF radio on oceanic routes. Allows crews to turn down background noise while monitoring for their unique SELCAL code.
Why Selective Calling System Matters for Pilots
Understanding Selective Calling System is important for pilot certification exams and safe flight operations. This concept appears on FAA and EASA knowledge tests, and examiners may ask about it during oral checkrides. A thorough understanding of Selective Calling System helps you make better decisions in the cockpit.
Exam Tip
This concept is commonly tested in communications-related questions on FAA and EASA exams. Make sure you can explain Selective Calling System in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
