What Are the Advantages of Pulling Banner Ads with Helicopters?
If you have ever been to a beach or sporting event, you might have seen a banner or billboard pulled behind a plane, advertising something. These signs tell of products or services, announce a special event, tell where to find further information (like a webpage), display political ads, and are used many other ways.
Probably these banner or billboard ads you saw were pulled behind a small single engine prop plane. Such a plane has sufficient power to pull the extra weight as well as the drag of the banner. But some companies offer banner ads that are pulled behind helicopters. This idea has pros and cons over the standard airplane.
First, helicopters are of course, much more versatile than planes. This makes them much more difficult to fly than airplanes. Therefore, special pilot training is required and this means greater expense. This maneuverability of the helicopter also demands much more from the engine. This means higher fuel costs and, again, more expense to the renter.
Normally you have 17 seconds to read banner ads pulled behind an airplane. Because helicopters can fly slower, this time can be greatly lengthened. Of course, if they are pulling a banner, they must go fast enough to keep it unfurled. But a billboard can be hung below a helicopter like a stationary billboard in the sky.
Conventional banner and billboard ad pulling involves attaching a rigid pole or support to the front of the banner so that it stays perpendicular to the ground. With weights attached to the bottom of the banner, it remains readable throughout the flying time.
Some use another method when pulling the ad behind a helicopter. It is called a Sling Load. Instead of using a rigid pole, the tow rope is attached just to the upper corner of the banner. A heavy weight of as much as 500 pounds is attached to the bottom front corner so that it stays upright. When the plane goes too fast, the message easily distorts with this method. Also, carrying that much weight poses a safety risk. The standard method requires only ten pound weights to keep it upright so the load is a lot less.
The advantage of the helicopter in pulling the banners is in the power of the plane. Because helicopters pull upward, and because their engines are much larger, they are able to pull much larger banners. Instead of the standard 3000 square feet sign, some have pulled banners as large as 50,000 square feet! Single engine planes would not be able to do this.
Both an airplane and a helicopter make enough noise to attract the attention of the spectators. Both methods provide the advantage of having a message presented to a large audience without competition in a very short period of time. And because of the unique presentation, it is almost guaranteed that the people will read it when it is flown overhead.
When you are confident your message appeals effectively, it is time to contact an aerial advertising company and begin the process of getting it into the air. In no time, your well planned message will be presented to thousands of people and the impact for you will begin to be seen.
