Rudder String Potentiometer

Rudder String Potentiometer

A string potentiometer has been interfaced to the rudder mechanism. Although not cheap in comparison to the other conventional potentiometers available in the market, the ease of use, smooth movement, accuracy and time it takes to implement the system outweigh the expense. The potentiometer was purchased directly from the CALTSensoR store on Alibaba – linear … Continue reading

Dual Link Rudder Pedals

Dual Link Rudder Pedals

One of the more challenging aspects of building the simulator – designing the foundation to mount the dual link rudder pedals. The Airbus OEM pedal mechanisms are fixed on the cockpit sub-structure and 10 mm thickness floorboards slide on top of the pedestal itself. The foundation frame engineering must be precise – it must be … Continue reading

Rudder Trim Control Loading

Rudder Trim Control Loading

I had the opportunity to spend some time in a Level-D A320 sim last week. Proper implementation of the rudder controls of the aircraft in a home simulator requires the use of control loading (force feedback). Reviewing the logic of the Level-D aircraft rudder function was of high interest to see how this could be … Continue reading

Brake Pedal Dampers

Brake Pedal Dampers

The brake control master cylinders are now installed on the First Officer (FO) side rudder mechanism. Linkage bars connect the FO and Captain side allowing for dual link control. The pedal dampers are also connected to a hydraulic reserve filled with skydrol fluid, however after testing it was determined there was adequate resistance in the … Continue reading

Floorboards

Floorboards

The floorboards of the aircraft are mounted onto the aluminium structure of the aircraft. Made out of composite material, they help to distribute the weight of the pilots and the cockpit seats. Measuring 10 mm in thickness, floorboards are designed to slot below the substructure interior liners.         When designing the structure … Continue reading

Progress Report

Progress Report

When you literally have hundreds, if not thousands of parts lying around waiting to be put together (a giant jigsaw puzzle) you may tend to have multiple mini-projects developing concurrently. The following solutions are currently being developed – ASI integration with a digital servo (thank you Mick) RMP refurbishment / repair Trim Wheel software/hardware implementation … Continue reading
