Each controller card has been independently programmed and wired to operate on a separate system. This redundancy has been duplicated by using two Alpha Quadrant controller cards, rather than a single card. In the real aircraft to provide for redundancy, each auto pilot system is separate. Most throttle units only use one motor controller card which controls either CMD A or CMD B whichever autopilot you select is controlled by the same card. Whenever possible, these systems and their logic have been faithfully reproduced.ĬMD A/B Autopilot - Two Independent Systems The cards act a 'bridge' between the card and the avionics suite - "call it a language transfer if you will."īeing able to program each card allows replication of real aircraft logic and systems. The Alpha Quadrant cards provide the logic from which the automation of the throttle unit operates.

One of the benefits of the card is that it utilizes a software chip (firmware) that can be easily upgraded ore replaced. The technology is also used to control robots used in the car industry and in other mass production streams. The technology used in the controller card is very similar to that utilized by NASA to control their robotic landers used in the space industry. The software to program the card has been independently developed by a software engineer and does not utilize Phidgets. The controller card I have used is not a Phidget card but a specialist card often used in robotics (Alpha Quadrant card). The interface cards are mounted forward of the MIP within the Throttle Interface Module (TIM) and are connected to the throttle unit by custom VGA cables and to the computer by a single USB cable.

Calibration of this card is done first in Windows, then in Flight Simulator (FSX/P3D), FSUPIC or the avionics suite used for example, ProSim737.

Leo Bodnar BUO 836 A Joystick Controller Card: This card will register in Windows the movement of levers, buttons and switches on the TQ. The card does not provide movement for the throttle thrust levers this is controlled by a Phidget Motor Controller card.

Phidget Advanced Servo Card (2): This card acts as an interface and bridge between the Alpha Quadrant cards and the flight simulator platform used. One card controls Auto Pilot CMD A while the other card controls Autopilot CMD B. To acheive this seemlessly, two interface and one controller card are used.Īlpha Quadrant Cards (2): Each motor controller card has the automation logic programmed directly to the card (via propiety software).

These N1 limits and targets are provided by the Flight Management Computer (FMC) and normally are used by the Autopilot Flight Director System (AFDS) and the Auto Throttle (A/T) to maintain airspeed and/or thrust setting.Īutomation and Movement - Interface CardsĮssentially, automation is the use of CMD A or CMD B (autopilot) to control the %N1 outputs from the Autothrottle (logic), and motorization is the moving of the throttle levers in unison with %N1 output. To avoid confusion, automation refers only to the movement of the two throttle thrust levers in relation to the %N1 output. The switch is linked to the IAS/MACH speed window (adjacent) and to two A/T disconnect buttons located either side of the throttle lever handles. LEFT: The Autothrottle arming switch is a solenoid operated switch clearly identified on the main Instrument Panel (MCP). Part of this post will be repetitive as I briefly discussed automation in an earlier post. We will also briefly discuss the use of potentiometers. In this final post dealing with the conversion of the throttle quadrant, we will discuss the automation and movement of the throttle thrust levers and look at some of the teething problems encountered during the throttle conversion.
