### Overview

This is an attempt at using a single archive to distribute all the files needed to model an aircraft in FlightGear. This archive should be extracted into directory $FGROOT/Aircraft/t6texan2. Some files will then need to be moved to other directories. I've attempted to keep as many of the files in directory $FGROOT/Aircraft/t6texan2 as possible. Ideally I'd like to keep all the files in one directory, but currently FlightGear requires some of them to be placed elsewhere. The contents of the archive, and the directory in which each file or directory should reside, is listed below.

### Contents

filename | description | placement
--- | --- | ---
t6texan2-read-me.html | This Readme file | $FGROOT/Aircraft/t6texan2
t6texan2.xml | The flight model | $FGROOT/Aircraft/t6texan2
t6texan2-set.xml | The main configuration file | $FGROOT/Aircraft
t6texan2-sound.xml | The sound configuration file | $FGROOT/Aircraft/t6texan2/Sounds
turboprop1.wav | The engine sound file | $FGROOT/Aircraft/t6texan2/Sounds
PT6A-68_sim.xml | The engine configuration file | $FGROOT/Engine
t6 | A shell script wrapper for fgfs | ~

directory name | description | placement
--- | --- | ---
Sounds | Contains .wav files and sound configuration for the T-6A | $FGROOT/Aircraft/t6texan2
Models | Contains the T-6A 3D model | $FGROOT/Aircraft/t6texan2

### Bugs

I'm still fairly new to FlightGear, so some of these "bugs" may actually be features :)

bug | status
--- | ---
3D model has some bugs | The model is a from the Captain Slug T-6A. The landing gear/wells/doors flicker. The model position has not been adjusted for FlightGear, so its wheels don't contact the ground properly. The gear and control surfaces don't move.
There is something wrong with the instrument panel | It's using the T-38 panel. See the T-38 read-me.

### Flying the T6-A

Takeoff, no flaps, apply full throttle. Sound doesn't change as engine is already at about 100%. Rotate at 110 knots and climb at 150 knots. To land fly downwind at 150 knots clean, on base slow to 120 knots, extending gear and half flaps passing through 130 knots. On final extend full flaps and slow to 100 knots. These speeds are guesses.
Let me know if you'd like more features, and if you have recent time in the T-6A let me know if this model flies reasonably close to the real airplane.

### Notes

The engine model uses the FGSimTurbine module of JSBSim. The thrust value in the engine configuration file is an estimated thrust for the engine/prop combination. Someday I'll add condition-lever inputs to the engine code.
