Sigma-Tek A/P Attitude Indicator
This is an air-driven (vacuum/pressure) primary attitude indicator designed to provide pitch and roll data directly to an aircraft's flight control computer.
Description
This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 02/11/2026.
Key Technical Capabilities:
- Autopilot Integration: Features internal inductive pickoffs that generate continuous pitch and roll stabilization signals to feed directly into Century Flight System (CFS) computers.
- Pneumatic Operation: Functions as an air-driven gyroscopic instrument relying on standard aircraft vacuum or pressure systems to power the internal brass rotor.
- Intuitive Attitude Display: Utilizes a moving horizon mask against a fixed miniature airplane to give the pilot a highly responsive, real-time depiction of climb, dive, and bank angles.
- Internal Lighting: Equipped with built-in 28V internal electrical lighting to provide clear instrument panel visibility during night and IFR operations.
- Regulatory Compliance: Built and certified to FAA TSO-C4c standards, making it approved for use as a primary flight instrument.
