๐ Radio Frequency Interference (RFI) Hunting at Davao International Airport โ๏ธ
As part of its flight inspection and validation functions, the Flight Inspection and Calibration Group (FICG) of the CAAP is actively monitoring for any RFI that may be affecting Radio Navigational Equipment, including GNSS and its applications to aviation.
The FICG is currently utilizing the Rohde & Schwarz DDF-007 Portable Direction Finder to tackle a significant issue at Davao International Airport. We have identified a local FM station transmitting at 329 MHz, which coincides with the frequency used for GPS correction of the Flight Inspection System (FIS) during flight inspections.
This matter has been reported to the Air Navigation Service (ANS) of CAAP Davao which will coordinate with the National Telecommunications Commission to address the interference.
Stay tuned for updates as the FICG and ANS work diligently to ensure the safety and reliability of our aviation operations!
