Aquarius Flight Data Computer

The AFDC system takes full advantage of todays technology by integrating a hydraulic pump system within Universal's AQUARIUS column architecture. The primary function of the AFDC is to accurately simulate the forces acting on the aircraft control surfaces in both static and dynamic conditions. The AFDC provides realistic levels of resistance to the columns during all phases of operation.. The dynamic pressures act on the control surfaces during taxiing, take-off, landing ground roll, and through entire range of the aircraft flight envelope.

HOW IT WORKS (below)

     

 









 

 


 

 

 


The AFDC communicates with simulation programs, such as Microsoft's Flight Simulator. The computer monitors flight data occurring in the simulation program. For example, parameters such as flap settings, speedbrake position, airspeed, altitude, wind speed, temperature, climb & decent rates. As data changes, the AFDC regulates the flow of hydraulic fluid to increase or decrease the resistance required to move the columns.

In addition, the AFDC incorporates its own stall warning protection system in combination with our USS-100 Stick Shaker Units (sold separately). As a impending stall situation increases based on airspeed and angle of attack, the AFDC sends a signal to trigger the shaker motors. Software coding sets a pre-determined time for the stall to be corrected. If after the pre-determined time the stall still exists, the AFDC will signal the hydraulic pump to push the columns forward (stick pusher).

Aircraft systems such as hydraulics can be further simulated by interfacing the AFDC with the overhead hydraulics panel. For instance, the columns will move forward and lock when the hydraulics are toggled in the OFF position. Bringing the switch to the ON position will center the columns for flight.

A safety shutoff switch, located on both columns, can be activated at any time to squelch any signals being sent by the AFDC.

Software coding is included with the AFDC.
