What Is A Reliever Airport?

Sun Jul 22, 2007 9:43 am

I was Googling an airport that is nearby my house, Lake In The Hills Airport, in Lake In The Hills, Illinois. Their website says that they are "a designated FAA reliever airport for Chicago O'Hare." What does this mean? Does that mean if something happens at ORD that they can take traffic there?

After I hit the post button, I was thinking. Are they called this because they take the GA traffic away from ORD?

An airport that takes traffic away from a primary airport in the region (like ORD) is a reliever airport. It doesn't just have to be GA either.

They are indeed. However, just because an airport is a reliever airport doesn't mean it only caters to GA (though I'm pretty sure no airline traffic will be visiting Lake in the Hills anytime soon). HPN is a reliever airport for New York, but has a lot of airline traffic.

A Reliever airport is a designation by the FAA. It is basically a high capacity general aviation airport in a major metropolitan area. There are specific requirements, however.

Quote:
Due to different operating requirements between small general aviation aircraft and large commercial aircraft, general aviation pilots often find using a congested commercial service airport can be difficult.9 In recognition of this, FAA has encouraged the development of high capacity general aviation airports in major metropolitan areas. These specialized airports, called relievers, provide pilots with attractive alternatives to using congested hub airports. They also provide general aviation access to the surrounding area. To be eligible for reliever designation, these airports must have 100 or more based aircraft or 25,000 annual itinerant operations. The 274 reliever airports have an average of 232 based aircraft, which is 29 percent of the nation’s general aviation fleet.

Those are technically reliever airports, while they do help ease the congestion at LAX. Reliever airports around Los Angeles include FUL, HHR, SMX, and VNY.
