PalmEFIS is for pilots who wish to take the technologies of a glass cockpit and put them to work on a business tool that they may already own, a Palm Handheld computer. The combination of the PalmEFIS software, a Palm Handheld and a GPS unit creates a powerfull tool that excels over most rivals. While PalmEFIS is an obvious attraction to VFR pilots it is also valuable to IFR pilots. PalmEFIS uses GPS feeds to drive its display features. As such it does not have the precision of a gyro driven artificial horizon and other instrumentation, but it will continue to work through failures that would render the ordinary equipment useless. PalmEFIS is the third vote that helps pilots to immediately identify the faulty instrument. Its that one more chance to get you out of the clouds in one piece. The major PalmEFIS features: * Aircraft Speed (GS, TAS, and IAS) * Heading (TC and MH) * Altitude (pressure and density altitude) * Attitude * Wind speed and direction * Headwind and crosswind components
