StudyWhich radio frequency is used for airport advisories?
- ❌A:121.5 MHz
- ✅B:Common Traffic Advisory Frequency (CTAF)
- ❌C:243.0 MHz
Explanations
- A: 121.5 MHz is the international emergency frequency, not used for airport advisories. Using this frequency for non-emergency communications could interfere with emergency signals and potentially lead to safety issues, regulatory violations, and negative business impacts.
- B: Correct. The Common Traffic Advisory Frequency (CTAF) is used for airport advisories, particularly at non-towered airports. Understanding and using the correct frequency is crucial for maintaining safety, regulatory compliance, and efficient business operations.
- C: 243.0 MHz is a military emergency frequency, not used for airport advisories. Unauthorized use of this frequency could lead to serious safety issues, regulatory violations, and negative business impacts.
🧭 Instructor Note
Why This Matters for Your Business
Understanding and using the correct radio frequency for airport advisories is crucial for any drone business operating near airports. Miscommunication or lack of communication can lead to safety risks, regulatory violations, and potential business disruptions.
Safety & Liability Considerations
Using the wrong frequency, such as an emergency or military frequency, for non-emergency communications can interfere with critical signals, leading to potential safety issues. It's crucial to maintain safety and avoid collision, damage, and injury, as well as potential fines or legal issues.
Consider This Scenario
A drone inspection company is contracted to conduct a survey near a non-towered airport. The drone operator needs to communicate with other aircraft in the area to coordinate their operations. Using the correct Common Traffic Advisory Frequency (CTAF) for airport advisories ensures safe and efficient operations, avoiding potential conflicts with other aircraft and maintaining regulatory compliance.
What the FAA is Testing
The FAA is testing knowledge of radio frequencies used in aviation, particularly for airport advisories. This includes understanding the purpose of different frequencies and the consequences of using the wrong frequency.
Business Success Strategy
Ensure all drone operators in your business are trained in correct radio communication procedures, including the use of the CTAF for airport advisories. Regularly review and practice these procedures to maintain safety, regulatory compliance, and efficient operations.
Memory Aid
Remember "CTAF for Advisories" as a simple mnemonic to remember that the Common Traffic Advisory Frequency (CTAF) is used for airport advisories.
