Cageable Attitude Gyroscopes
5000M-series
-
The 5000M is an air-driven gyro that has a pictorial horizon mask and fixed airplane. The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are displayed so that the pilot’s sensing of the gyro indication is the same as the interpretation of the relation between the wings of the aircraft and the natural horizon during visual flight.

Standard Directional Gyroscopes
4000B-series
-
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

True Airspeeds
-
These true speed indicators are differential pressure indicators that measure the difference between static and total pressure produced by ram air from the pitot. The indicated airspeed can be corrected for changes in altitude by turning the knob to align the outside air temperature with the altitude. The moveable airspeed scale will then show the actual, or true, airspeed.

4000B ARINC-style Directional Gyroscopes
-
This instrument was developed for those pilots that prefer the distinct, professional look of an ARINC-styled cockpit. It is identical to the standard 4000B model differing mainly in aesthetics. Besides its distinct bezel and airplane, the display graphics and colors differentiate it from the standard model. A heading reminder bug is available as an option.

Dual Fuel Gauge
1U432-series
-
The 1U432 dual fuel gauge is packaged as a compact, 3” instrument. It has dual D’Arsonval movements that are driven by two resistive bulb transducers in the fuel tanks. The two opposing pointers stand out sharply from the non-reflective black background.

ARINC-style Attitude Gyroscopes
1U367-series
-
The 1U367 has a pictorial horizon mask and a fixed airplane. The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are diaplayed so that the pilot's sensing of the gyro's horizon indication is the same as the interpretation of the relationship between the wings of the aircraft and the natural horizon during visual flight.

Electric Attitude Gyroscopes
5000EG-series
-
The 5000EG gyro is based on our air-driven 5000B model, whose proven reliability has made it the industry standard for many years. There are two models available: 14 and 28 VDC. The rotor is precisely machined from a heavy-metal tungsten alloy, which has a higher mass than brass, contributing to the instrument’s demonstrated stability. The electric motor is driven by a built-in power inverter, and has an integrated air-erection mechanism. A warning flag is deployed upon loss of primary power. During acrobatic flights or short stops, the gyro’s mechanism can be caged whenever the knob is pulled.

Autopilot Attitude Gyroscopes
5000E/L-series
-
The 5000E air-driven attitude gyro is another variation of our standard 5000B model. It includes inductive pickoffs that generate the signals necessaryto drive an autopilot. The intuitive display has a moving horizon mask that indicates the position of the aircraft’s wings in relation to the natural horizon. This attitude information is passed along to the autopilot system.
