Quick Answer
To dismiss ground-to-air signals if unnecessary, you should extinguish or disable any visible signal sources, such as flares or strobe lights, and cease transmitting radio signals. This procedure is essential to avoid attracting unwanted attention or interfering with legitimate air traffic. It should be done as soon as the signal is no longer required.
Disabling Signal Sources
To extinguish flares, use a fire extinguisher rated for Class B or K fires. Aim the nozzle at the base of the flare and spray until it’s fully extinguished. For strobe lights, switch off the power source or remove the batteries to disable the device. If using a portable radio transmitter, turn off the device or switch to a non-transmitting mode.
Securing Radio Frequencies
To prevent radio frequency (RF) interference, switch off your radio transmitter or switch to a non-transmitting mode, such as a receive-only frequency. If you’re using a handheld radio, ensure the antenna is fully retracted to minimize RF emission. For base stations, ensure the transceiver is set to a non-transmitting mode or powered off.
Visual Signaling Cessation
For visual signals using flags or mirrors, fold or stow the devices to prevent any accidental signaling. If you’re using a signaling device, such as a whistle or horn, ensure it’s silenced and secured to prevent accidental activation. This will help maintain situational awareness and avoid unwanted attention from air traffic or other parties.
