Many of my a/c have more than one altimeter i.e. main/standby altimeter. When I change the QNH both the standby and main altimeters change. Is it possible to isolate each altimeter? Reason being is that it is normal practice to have in flight one showing 1013mb and the standby on QNH. This is particularly important in the climb and descent phases of the flight.I remember well in FlyII having a fully functioning cabin pressurisation gauge. Can this be done in FS9? Are there any examples?vololiberista

For both items you will have to write custom code.

Property Descriptionaltimeter.0toaltimeter.nIf the parameter is set to 1, a separate altimeter is instantiated, which will operate independentlyExamples:Airbus A321 Paint2( altimeter.0=1Airbus A321 Paint2( altimeter.1=1Learjet 45( altimeter.0 = 1Learjet 45( altimeter.1 = 1

If we can have separate altimeters, surely there must be a way to set the kohlsman idependently also?It's certainly possible in XML, so it should also work in C, if the index is provided.

Those are for FSX... FS9 has no such settings. He asked about FS9.

Really? That's not what the FS9 SDK states:

[airspeed_indicators] sectionThis section is used to define the characteristics of the airspeed indicators on the instrument panels. The list of indicators should be listed in order: 0,1,2,

Thanks very much for your guidance.vololiberista

Ok, he asked about altimeters... not airspeed. You referenced altimeter entries in the aircraft.cfg that is defined in the FSX SDK but not the FS9 SDK.

Oops! That's what happens when I'm tired from a long day......I'll go back to standing in the corner wearing the silly conical cap now... :(

Does that mean it is not possible in FS9?vololiberista

As I already stated for FS9 you must write your own code to accomplish what you seek.

Can't you just do a conversion from indicated altitude to pressure altitude in reverse?

Having been a pilot for more than 40 years I am well capable of converting pressure readings!!! My point however, is that multiple altimeters on panels should be independent of each other. Whereas they are not in FS9.vololiberista

I wasn't questioning your skills. :( What I wanted to suggest was that if you can go from indicated altitude to pressure altitude then you can also go the other way.FS9 can give you the pressure altitude and with it you could calculate the indicated altitude for any given barometer setting.

Hi,What i remember about the standby altimeter is:Add a L:Var to the indicated altitude and adjust it with the baro knob.I 've lost the "scientific" backgroundUsed for indication in numbers and for needle rotation: (A:Indicated Altitude,feet) (L:KOHLSMAN,number) 3386.53075 * + and for the knob just:(L:KOHLSMAN,number) 0.01 - (>L:KOHLSMAN,number)(L:KOHLSMAN,number) 0.01 + (>L:KOHLSMAN,number)and to set QNE or QNH for both altimeters:(L:press,enum) 0 == if{ 1 (>L:press,enum) 16210.5 (>K:KOHLSMAN_SET) 0 (>L:KOHLSMAN,number) } els{ 0 (>L:press,enum) (>K:BAROMETRIC) 0 (>L:KOHLSMAN,number) } For the readout in mbar: %((A:KOHLSMAN SETTING HG,mbar) (L:KOHLSMAN,number) 33.8653075 * + )%!d!and inches hg: %((A:Kohlsman setting hg,inHg) (L:KOHLSMAN,number) +)%!2.2f!About pressurisation, have a look here:http://forums1.avsim.net/index.php?showtop...n+presurisationHope it helps,Jan
