Antonov An-12BK Aircraft development for FlightGear

Introduction

FlightGear is an open source flight simulator that is even used in flight schools to train basic maneuvers, radio communication and navigation tasks. I became aware of this project 3 years ago and have build my own hangar with 18 aircraft and vehicles.

My first contact with programming an aircraft was the old Antonov-12 as the existing model in FlightGear has no steering, no instruments and very bad flight behavior.

By working on the cockpit for half a year I got the basic instrumentation knowledge and the ability to make changes in Blender and Gimp to fit all together in a realistic manner.

Much more time goes into the Multiplayer animations and adjusting the FDM (Flight Dynamyic Model). You may load 120 paratroopers or 6 cargo-boxes and drop them via parachutes to any simulated mission you like to do.

An other big task was the "rembrandt" light system in FlightGear which makes lights as realistic as possible. It means that all instruments and parts had to be defined for the normal light system and this special one.

In this article I want to introduce my development of Antonov-12BK.
