An airplane GPS is something that most pilots consider necessary. While most of the commercial planes sold today have their own global positioning systems, this is not always the case with the smaller private planes. If you fly in these small, private planes chances are you will need to buy your own system. These systems can come in very handy as they will let you know what the terrain is like below you and will also let you know about points of interest.

When you begin shopping for a global positioning system you will find that there are a lot of different options. You'll notice that the systems range in price from $500.00 to up over $8,000.00! The differences between these systems can be substantial, but the most expensive unit isn't necessarily the unit that is best for you. You will want to shop around a bit and see what is out there and what features there are to choose from before you buy.

The first thing you will want to consider is screen size. Many of the aviation GPS units have a very small screen that will require that you actually pick the unit up and bring it closer to your face because the screen is just a few inches wide. Other units will have very large screens that will actually need to be attached to the interior of the plane. If you are looking for portability you will obviously want the smaller units, but then you have to look at if these smaller units fit your needs.

You will also want to look at whether or not the GPS has audio capabilities, as it is often very convenient to have the system talk to you and tell you what is going on. For instance, it can tell you about upcoming obstacles, points of interests, or the type of terrain that is located below. These are things that may be better heard than seen on a screen. Many of the systems come equipped with aviation headset ports that will allow you to hear the GPS system regardless of the noise that comes from the engine of the plane.

The best thing you can do when shopping for your system is to look into several different brands and look at the differences between the price points and what you can get for the money. Ask your friends and business partners what systems they use, read as many consumer reports as possible, and do some hands on shopping before you buy. Regardless of the price of the unit you buy, a GPS is an investment and you want to be sure that you get a system that will provide you with all of your needs as you go along.
