FGproperties/Systems
By Default systems are initialized by the Aircraft/generic/generic-system.xml
This initializes the following:
- The generic electrical system
- 1 pitot system, index [0]
- 1 static system index [0]
- 2 vacuum systems [0] and [1], depending on engine rpm of engine[0] and engine[1] respectfully

FGproperties/Systems/Pitot
and
FGproperties/Systems/static
If you want to define more systems, copy the generic-system file to your aircraft-name/Systems folder and rename it systems.xml
In your aircraft -set file add the path to the system.xml file:
<sim>
...
<systems>
....
<path>Aircraft/aircraft-name/Systems/systems.xml</path>
....
</systems>
...
</sim>
Adding a second pitot system
In your systems.xml, you should already have
<pitot>
<name>pitot</name>
<number>0</number>
</pitot>
and you need to add for a pitot system with index 1:
<pitot>
<name>pitot</name>
<number>1</number>
</pitot>
For the any pitot system except for the first (with index 0) add in the aircraft -set file (below for index 1):
<systems>
...
<pitot n="1">
<serviceable>1</serviceable>
</pitot>
...
</systems>
Of course you can add a third or fourth etc.
Adding a second static system
Absolutely analog with the pitot system. So add in systems.xml:
<static>
<name>static</name>
<number>1</number>
<tau>1</tau>
</static>
and in the aircraft -set file:
<systems>
...
<static n="1">
<serviceable>1</serviceable>
</static>
...
</systems>
Now you can source your instrumentation relying on static and pitot pressure (airspeed, altimeter, vertical speed indicator) from different and independent systems.
