Who is actually does the overhaul on the Sigma Tek 5000B-36 Gyros? Is it Sigma Tek?
Yes, the overhaul is done at Sigma-Tek.
How much is the core charge?
You can add 10-03360 (Sigma-Tek Factory O/H 5000B-36) to your cart and it will then show you the current core charge.
Is this overhauled Sigma-Tek Attitude Gyro 5000B-36 unit TSO'd? I plan on using this on a certified aircraft.
Per Sigma-Tek: Yes, this unit is TSO'd.
Is this an electric gauge?
This is a vacuum gauge.
Is this unit equal to the EDO AIRE 52D67 who connects to the autopilot?
No, this 5000B-36 is a vacuum attitude driven attitude indicator with no autopilot connection.
Does the Sigma-Tek 5000B-36 have a flag for vacuum fail?
The -36 version does not have this feature.
Will Sigma-Tek accept a 5000E-8 as a core? I have a stec 55 auto pilot so I no longer require the auto pilot feature from the Attitude Indicator.
No, because the Sigma-tek 5000B-36 is an overhauled unit the 5000E-8 can not be used as a core. If you purchase a new unit you may use this as a core.
I'm replacing a 5000B-10. Will this work? Also light p/n lw3014aa was installed with it. That light still works. Will it be fine for this one too? I am thinking I don't need to purchase a light.
Yes, the 5000B-36 is a direct replacement for the 5000B-10. The Nulite lighting will also work for this instrument.
