Of course the total and static pressure may be sourced from any other

pitot and static system when defined:

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>
|

<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
