Report

As an FAA-approved repair facility, United Instruments accepts both warranty and non-warranty instrument repair. We're committed to the philosophy that understanding the cause that led to the repair is just as important as the repair itself, and a responsibility to our customers that we never take lightly.

Turn and Slip

Report

The 9500 Series Turn and Slip Indicators have been designed with emphasis on safety and reliability. Conventional restraining coil springs have been replace by a single spiral torsion spring secured at the gimbal shaft. A patented viscous fluid device on the gimbal shaft dampens the gyro response to applied forces.

Vertical Speed

Report

The 7000 Series Vertical Speed Indicator is a precision instrument, which provides an accurate and reliable indication of rate of change of altitude. Ascent is indicated by a clockwise rotation of the pointer from zero. Descent is indicated by a counter clockwise rotation. Zero is at the 9 o'clock position.
