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.

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.

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.

Breakout Box and Data Logger
1U643-001
-
The 1U634 Breakout Box and Data Logger was developed for the Cessna Excel to serve as the main diagnostics tool for the aircraft?? electronic modules. It allows access to the module pins, and its internal microcomputer digitizes the signals and transmits them to a PC-compatible computer. Advanced software in the computer displays pin voltages either in numerical or graphical form. Data files can be recorded on disk, and played back at a later time for detailed analysis.

Data Monitoring System
1S663-001
-
The 1S663-001 Data Monitoring System was specifically developed for the Cessna Citation X and serves as the primary diagnostic tool for the aircraft?? electronic Logic Modules. The system is FAA certified for airborne operation. Aft compartment and cabin modules can be tested two at a time while remaining in place. The system is also capable of monitoring the fuel quantity system during flight.

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.
