In my current configuration (Ubuntu 12.04 and ROS Hydro), .dae 3D models, while loaded with no complaints from RViz, are not displayed. On the other hand, .stl files work fine,...

I'm still unsure wheter Pitot probes capture `Va` or `u`. In order to implement a realistic virtual Pitot probe, this should be clarified first.

This should also affect the inertia matrix J, filling all of its elements. **To support this, moment calculations should use the full inertia matrix.**

Right now gusts are modeled in last_letter using Dryden transfer functions. Alternatives exist - http://www.flightsimaviation.com/data/FARS/part_25-appG.html - http://www.flightsimaviation.com/data/FARS/part_23-333.html and should be investigated and possibly implemented.

There is a need to model transfer functions in the simulator, ie for model following. FIR are suitable for computer modeling but do not have accurate results, especially in steady-state....

Currently \eps (really small value) is used in the quaternion conversion code in _mathutils_ libary. Resources should be searched and documented, since this is an often confusing point in aerial...

Compare the current implementation against the US Std Atmosphere model. Documentation is welcome.

Actually these two model gravitational potential differently, due to different ellipsoid representation. Maybe model both and select at startup?
