AirPlan

AirPlan is a flight planning tool that is designed to assist pilots in the process of planning cross-country flights.

It automates the process of determining leg distance, fuel consumption, airspeed, time enroute, headings, magnetic correction of heading, and wind correction of heading.
It also provides a number of other tools and features for calculating weight and balance, obtaining weather information, maintaining an electronic logbook, generating a moving map, and additional support for handheld GPS units. Users of Microsoft Flight Simulator can also use AirPlan's moving map on the same PC by using a special interface module, or on a seperate PC using a Local Area Network or a null-modem cable.
A worldwide database of airports, navaids, waypoints, airspace boundaries, airways, and user waypoints is provided with the application.
