Of course the total and static pressure may be sourced from any other
pitot and static system when defined:
<airspeed-indicator>
<name>airspeed-indicator</name>

<static-pressure>/systems/static[1]/pressure-inhg</static-pressure>

</airspeed-indicator>
Note that the Aircraft/Generic/generic-systems.xml only initiates one
pitot and one static system, see also README.systems
<total-pressure> is optional --- defaults to "/systems/pitot/total-pressure-inhg"
For supersonic aircraft with an airspeed indicator NOT compensating for
a shockwave in front of the pitot tube (most probably the case), use:
<total-pressure>/systems/pitot/measured-total-pressure-inhg</total-pressure>
<static-pressure> is optional --- defaults to "/systems/static/pressure-inhg"
<has-overspeed-indicator> is optional --- defaults to 0 / off
The <has-overspeed-indicator> provides a property for "barber-pole" animation,
and is set to 0 / false by default ,
If enabled , these properties should be added in the set file ,
If enabled , these properties should be added in the aircraft -set file,
with that aircraft's correct figures.

This was designed for indicated airspeed limits, but could probably be extended
for mach limits.
To initiate additional airspeed indicators, add in your instrumentation
file (for airspeed indicator index 1):
<airspeed-indicator>
<name>airspeed-indicator</name>
<number>1</number>
<total-pressure>/systems/pitot[1]/total-pressure-inhg</total-pressure>
<static-pressure>/systems/static[1]/pressure-inhg</static-pressure>
<has-overspeed-indicator>0</has-overspeed-indicator>
</airspeed-indicator>
Note: this airspeed indicator sources its pressures from the second
pitot and static system (with index 1).
and in the aircraft -set file:
<airspeed-indicator n="1">
<serviceable type="bool" archive="y">true</serviceable>
</airspeed-indicator>
And if "has-overspeed-indicator" = 1, the appropriate limits as explained
above in the airspeed-indicator brackets.

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
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
