{{Caution|You may want to think about updates that happen every frame but are not
significant.
 
Several properties are constantly re-calculated but vary only at a very
high level of precision per frame.  One can subscribe constant flood of
updates that do not show up in a meaningful way on actual instruments and
represent changes in value that are neither visible nor actionable.  Fuel
is a good example, but also items like the attitude indicator and
altimeter.
 
You can observe these properties easily through a subscription in the
telnet interface or by refreshing individual items in the phi interface.
Just start the Cessna 172 and set the parking brake.
 
I think the ability to subscribe to changes at a specific level of
precision for updates to each property might prove useful.<ref>https://sourceforge.net/p/flightgear/mailman/message/37263821/</ref>
