Hi Two things I’m curious about. First, the documentation
(https://docs.flightsimulator.com/html/Programming_Tools/SimVars/Aircraft_SimVars/Aircraft_Electrics_Variables.htm#APU%20BLEED%20PRESSURE%20RECEIVED%20BY%20ENGINE)
seems to suggest that APU BLEED PRESSURE RECEIVED BY ENGINE only considers
bleed air coming from the APU. However, during experimentation in the A320neo,
I found that it also considers engine bleed as it matches the TURB ENG BLEED AIR:1 and TURB ENG BLEED AIR:2 exactly, even with APU bleed turned off.
screenshot above. I am wondering whether it’s intended for both engines to
provide bleed air to each other (according to
APU BLEED PRESSURE RECEIVED BY ENGINE) even when BLEED AIR ENGINE:1 and BLEED AIR ENGINE:2 are off? Ibelieve the reason for this behavior to be that
BLEED AIR SOURCE CONTROL is3, meaning the engines can provide bleed air. This is the case becauseBLEED AIR ENGINE:3 is set to on, so the system sees at least one engineproviding bleed air, even if the A320neo only has two engines. I find this
confusing because spawning on the runway shows all
BLEED AIR ENGINE:i to beon. Consequently, even turning off both
BLEED AIR ENGINE:1 and BLEED AIR ENGINE:2 will leave bleeds 3-99 (?) supplying bleed air, which is notcorrect. It also means that it’s possible to perform a crossbleed start on the
A320neo with both bleed air pushbuttons off. Alternatively, is there a way to
have only
BLEED AIR ENGINE:1 and BLEED AIR ENGINE:2 on duringinitialization? It doesn’t make much sense to have the others on when the
aircraft has only two engines? At the moment, it seems like the way to do it
would be by invoking the
ENGINE_BLEED_AIR_SOURCE_TOGGLE event to force allengine bleeds off, then manually turning them on for #1 and #2. Is there an
easier way through a .cfg or .flt file? Thanks for looking into this
