Difficulty: Moderately Easy
Step1
Don't panic. Go back to the last good frequency you had to see if that works.
Step2
Make sure all the connection cords and volume are working.
Step3
Try a different pair of headphones. Check to see if it is the hand held transceiver giving you problems. Keep talking to air traffic control as if they can hear you. They just might be able to.
Step4
Try different channels. Use the emergency channel 121.5 and keep talking.
Step5
Fly with a cell phone. Call 1-800-wx-brief to get the FSS Flight Service Station and let them know of your situation.
Step6
Keep your initial heading, especially if you have filed an IFR flight plan.
Head to the first fix point after the departure. Make sure you fly the assigned altitudes to avoid other aircraft. If you are flying VFR, land as soon as possible.
Step7
At approach, squawk 7600, the signal for lost communication. You can also squawk 7700 for emergency.
