I've just added a static port system and a new altimeter model to CVS. Now, if you set the property
/systems/static/serviceable to false, the altimeter will freeze. Otherwise, it displays the altitude based on the difference between outside air pressure (with a slight lag from the static port) and the altimeter setting, without any direct knowledge of the actual aircraft altitude. When I have a chance, I'll write a new VSI model, also connected to the static port. I'll also add a pitot system, then will write an ASI connected both to it and the static system. I need to know more about the ram-air effects in the pitot tube first. The static system itself needs a little more work, including support for multiple static ports, sideslip errors, and alternate air (from inside the cabin); those won't be hard to add, but if anyone (Alex?) wants to take a look at src/System/static.[ch]xx and add them in before I have a chance, feel free. Note that any improvements to the static system automatically propagate themselves to the instruments.
