The airspeed indicator can be initialized in an instrumentation.xml file.
|
||
|
|
If not specified, the generic indicator will be loaded
|
||
|
|
from the Aircraft/Generic/generic-instrumentation.xml.
|
||
|
|
|
||
|
|
The normal setup is :
|
||
|
|
|
||
|
|
<airspeed-indicator>
|
||
|
|
<name>airspeed-indicator</name>
|
||
|
|
<number>0</number>
|
||
|
|
<total-pressure>/systems/pitot/total-pressure-inhg</total-pressure>
|
||
|
|
<static-pressure>/systems/static/pressure-inhg</static-pressure>
|
||
|
|
<has-overspeed-indicator>1</has-overspeed-indicator>
|
||
|
|
</airspeed-indicator>
|
||
|
|
|
||
|
|
<total-pressure> is optional --- defaults to "/systems/pitot/total-pressure-inhg"
|
||
|
|
<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 ,
|
||
|
|
with that aircraft's correct figures.
|
||
|
|
|
||
|
|
<airspeed-indicator>
|
||
|
|
<ias-limit>248.0</ias-limit>
|
||
|
|
<mach-limit>0.48</mach-limit>
|
||
|
|
<alt-threshold>13200.0</alt-threshold>
|
||
|
|
</airspeed-indicator>
|
||
|
|
|
||
|
|
|
||
|
|
The default values are for a Beechcraft B1900D .
|
||
|
|
|
||
|
|
<ias-limit> is the aircraft's VNE (never exceed speed) in KIAS
|
||
|
|
|
||
|
|
<mach-limit> Mach speed limit.
|
||
|
|
|
||
|
|
<alt-threshold> altitude at which these figures were calculated.
|
||
|
|
|
||
|
|
Note : <mach-limit> is the mach limit at <alt-threshold>
|
||
|
|
This was designed for indicated airspeed limits , but could probably be extended
|
||
|
|
for mach limits.
