Handheld GPS for Aviation – An Overview
Aviation based handheld GPS devices serve as auxiliary navigation systems for the pilot. A desirable handheld GPS will have complete databases with some manner of providing regular updates of the mapping data. One should show all airports, including the closest or destination airport, the approach path, and the extended centerline of the runway. It is also a handy device at times of emergency.
GPS has brought great change to the personal aviation industry. It helps the pilot in many ways while guiding him/her with better accuracy than other navigational aids. Handheld GPS devices are only used for VFR (Visual Flight Rules).
Manufactures of handheld GPS devices for aviation have tough competition in the market. They come at different prices to suit different budgets. With the extreme competition among GPS vendors, it is natural that there will be a further thinning in handheld GPS models for aviation. Several products like Garmin GPSMAP-396, C-Map's EKP-IV, and the Honeywell/Skymap IIIC, which are costlier than similar feature-packed automotive color GPS devices, are heavily used by GA (General Aviation) pilots.

Handheld GPS for Aviation – The Market
Selecting the most reliable portable GPS for aviation is difficult. The main reason for this is that no one knows everything about the GPS aviation products. Pilots and mechanics are aware of only a few features. Local dealers are not experienced with most models that are available in the market. They often end up advising the customers on the wrong product. On the other hand, the magazine reviews do not reveal how the vendor determined the accuracy of GPS. Consumer magazines often select products of the year based on customer reviews of the different models. Many pilots chose products that do not suit their flying needs just because of ignorance about selecting a handheld GPS for aviation.

Selecting a Proper Handheld GPS for Aviation
Although it's certainly possible to go flying with the TomTom from your car, one of the best ways to select a handheld GPS to be used as a navigational adjunct is to find one that is easy to use.
Once you become accustomed to using a specific handheld GPS product, other products become difficult to compare. Those with more features take more time to learn, and the time to learn their menus and entry methods is on the ground, not in the busy cockpit.
Most handheld GPS, including those intended for aviation use, come with overlay information. These may include road maps with features such as motels, restaurants, and post offices.
Another important factor in ease of use is the number of keystrokes required to enter a route or waypoints. The product should be made in such a way that you should be able to use basic navigation and database features of the handheld aviation GPS device without constantly referring to the manual. You should be able to remember how to operate the device even after a long time gap, and you should be able to remember the keystrokes without having to stress your memory.
