S-tec issues

[Cris]

Attached are a few pictures of an S-tec pressure transducer. At issue is the tube extending from the transducer. Should it be attached to the static line or not? In diagnosing an issue with the HSI I got under the panel only to find that a static line near to the pressure transducer is capped off with a temporary fitting. I'm thinking this occured as a result of a pitot static IFR cert. last year. It would seem that it never was replaced and I have been using inside cabin pressure to set the altitude on my S-tec 30. But as I am not sure that the static line should be attached to this transducer I thought I'd ask if anyone knows the answer? Separately I have an S-tec St-180 HSI compass system. The compass system part is not working. I need a St-6444 or St-6444-01 remote gyro. Does anyone have one that they have removed for upgrade. Thanks.

my pressure transducer is in the tail cone and is connected to the static port.

i am thinking that if it is not connected to the static line, it is not that consequential butyou would have a slower response time.

i have a pss-60 that can hold a VS or intercept a glide slope. in this case it has to be connected to the static line.

in any case, it is best to get it right and connect it to the static line.

yes it must be attached. Inside aircraft / outside aircraft statc pressure are not the same especially when climb / decent / maintain alltitude.

Static line ....

Thanks to all! Now if I could only find someone who wants to sell an S-tec remote gyro..

P.S.I. in corona is the only company that services the S-Tec remote gyro....It is the only one with the outputs you need ....The aeronetics is the same ......
