You're facing radio interference during landing. How do you manage communication with the control tower?

1 Verify Frequency

Ensure that you're on the correct frequency. It's surprisingly easy during the busy landing phase to mistune your radio or inadvertently switch channels. Double-check the frequency against the one provided by Air Traffic Control (ATC) in your pre-landing briefing. If you're still experiencing interference after confirming the frequency, inform ATC of your situation using clear and concise language, so they're aware of the communication issue.

2 Signal Checks

If the correct frequency is set, perform a radio check. Ask the control tower for a signal check, stating your call sign and the nature of your issue. They may offer an alternative frequency or relay your messages through another aircraft if necessary. Remember, clarity is key; ensure each transmission is as brief and as clear as possible to minimize the chance of miscommunication.

3 Nonverbal Cues

When radio communication is unreliable, you can resort to nonverbal cues. Aircraft are equipped with transponders that can squawk specific codes to indicate emergencies or radio communication failure. Squawk 7600 on your transponder to alert ATC that you're experiencing radio failure. This code will prompt ATC to look out for your aircraft and provide light signals or other forms of communication for landing clearance.

4 Light Signals

If you've set your transponder to 7600, watch for light signals from the tower. These visual cues will guide you safely to the runway. A steady green light indicates clearance to land, while flashing lights have different meanings depending on their color and pattern. Familiarize yourself with these signals in advance, so you're prepared to respond correctly under stress.

5 Backup Radios

Use backup communication systems if available. Many aircraft are equipped with more than one radio to ensure redundancy. If you're facing interference on the primary radio, switch to a secondary unit. This might resolve the issue if the problem is with the equipment. Be sure to inform ATC immediately upon re-establishing communication so they can update your status.

6 Visual Approach

In the event all communication efforts fail, prepare for a visual approach if conditions permit. Keep a lookout for other traffic and follow standard traffic patterns while observing light signals from the tower. Maintain situational awareness and be ready to go around if you're unsure of your clearance to land. Safety should always be your top priority.
