The predecessor, nDAC, was launched in October 2004 and has since seen three major revisions. In its fourth revision, a number of functions requested by Navigraph users have been implemented. For simplicity the product has also been renamed from an acronym to just Navigraph Charts 4.0.
We are proud to offer the flight simulation community professional airport charts provided by Navtech. The chart format is based on research by human factors specialists and subject matter experts. The aim is to describe approach and departure procedures from airports with a clear presentation of altitudes, obstacles and landing minima during Instrument Flight Rules. Each chart also features a communication box which displays all the relevant frequencies for the current stage of flight.
The worldwide coverage of enroute charts is delivered by Navtech. The charts show the upper and lower airways, waypoints, and altitudes over a larger area. The enroute charts are downloaded through a client which allows zooming the vectorized graphics of select areas to enlarge details.
