The Airbus trim wheel can be interfaced directly with Jeehell FMGS using the Sidentus Trade & Technology GmbH FDSMotorTrimWheelCtr software. Requirements – Jeehell FMGS, PhidgetMotorControl HC, FSUIPC (registered), potentiometer (joystick) I/O, Phidget21 Libraries First ensure the trim has been mechanically setup correctly. A DC motor attached to a clutch and gears connected to a potentiometer … Continue reading

Pedestal Refurbishment
The thrust pedestal refurbishment is pretty much complete. Knobs have been repainted with the assistance of Cockpit Concept. A big thank you to Mick for helping out with the flaps panel – it was in a terrible shape prior to the repaint. The Simulator Solutions converted MCDU units have been installed. Motorisation of the trim … Continue reading
Tutorial: Configuration of the Motorized Trim Wheel
The following is a tutorial on how to setup a motorized trim wheel using a Pololu hardware feedback interface board and ProsimA320. Alternative avionics software such as Jeehell FMGS does not have native Pololu compatibility and will require additional driver support, such as FSUIPCtoPololu from TNS-Systems. Hardware trim setup can be reviewed over here. Wire … Continue reading

Simon’s Motor Trim Implementation
Some notes from Simon: Opencockpit DC Motor Board (interfaced with SIOC) Takanawa 555 metal gear DC motor, attached to home made plastic motor carrier bracket Lower trim axis rotates six times, multi-turn pot rotates ten times; requires a gear ratio 1.5 or 1.6 (45 vs 30, or 48 vs 30 teeth) Original movable joint if motor … Continue reading
Trim Wheel Motorization – Methods
There are several ways to motorize the trim wheel of the Airbus. The A320, unlike the Boeing 737, has autotrim built into the aircraft systems. Boeing pilots are required to trim the aircraft to an angle of attack of 1 G — this is done with the trim switch on the yoke. On the A320 … Continue reading
