Present Position Computer

A Present Position Computer (PPC) is a type of flight instrument that is used in aviation. It is part of the supply class Flight Instruments, which falls under the supply group Instruments And Laboratory Equipment.

The PPC is designed to calculate and display the current position of an aircraft in real-time. It takes inputs from various sources such as GPS (Global Positioning System), inertial navigation systems, and other navigational aids to determine the aircraft's latitude, longitude, altitude, and other relevant information.

The PPC uses advanced algorithms and data processing techniques to accurately calculate the aircraft's position and display it on a screen or other visual interface. This information is crucial for pilots to navigate and maintain situational awareness during flight.

In addition to providing the present position, some PPCs may also offer additional features such as route planning, waypoint navigation, and integration with other avionics systems.

Overall, the Present Position Computer is an essential instrument for pilots, enabling them to accurately determine their aircraft's position and navigate safely during flight.
