Looking for good tutorial on installing vacuum-driven gyro instruments.

[MattMoose]

Hi all,

I'm looking for a good tutorial on installing vacuum driven gyro instruments in an experimental aircraft. I understand the basics, but not the finer points yet!

:confused: Questions arising:

1) should instruments be connected to vacuum in series or parallel,

2) what sort of regulator should be obtained & where from (UK),

3) does the regulator need constant adjustment throughout this aircraft's 20,000ft operating ceiling,

4) what would the estimated, combined flow rate in l or cu.ft. per second be, for a horizon gyro and a heading indicator?

Many thanks in advance.

Hi MMoose.
I have had no dealings with this company, but it may be worth a quick 'phone call or email.
It may also be worth Ringing the PFA, as I have had a good response from PFA Engineering last year with a question I had (Not related to instruments)

I have a question, reading the post again.
I fail to see how the instruments COULD be connected in series. There is only a vaccuum conection and the static air input, normaly via a internal filter if I recall. Therefore, as I see it they could obviously only be connected in parallel.
