Here is a method for submitting noise complaints more easily than running to a computer.
First, download a flight tracker application. FlightRadar24 is a pretty user friendly one and will provide info ranging from flight origination, type of aircraft, and altitude. (Remember to subtract the 748 feet above sea level to get actual Charlotte altitude.)
Next, bookmark the noise complaint form on your phone by visiting the website and opening the form. You can bookmark the form for convenient access.
