Control Loading

The original mechanical control loading system is currently being modernized step by step. As part of the first phase, the original roll-axis mechanism has been removed and replaced by a modern Moza AY210 force-feedback base.

The AY210 is an off-the-shelf industrial force-feedback unit featuring:

• 9 Nm torque,
• 210 N push force,
• and 150 mm travel distance.

For integration into the Link Trainer, the original AY210 front panel was completely removed. The original power switch had to be reinstalled externally because it was integrated into the removed front panel.

Due to structural limitations inside the cockpit, the yoke base had to be relocated further to the rear, requiring an extension of the center shaft. To better match the overall appearance of the simulator, the modified components were also given a slightly more vintage look.

The first tests already demonstrate highly realistic control forces together with synchronized instrument indications. At the moment, Manifold Pressure (MP) and RPM are already fully operational. 

The videos show a short engine start, run-up and shutdown sequence, as well as the automatic internal calibration of the control axes and force-feedback system during power-up.

Landing Gear and Flap Position Indicator

To operate the instrument, the original 'ROTATABLE CONTACT ARM' is being electronically simulated. A small motor drives a slide potentiometer to generate the corresponding reference voltages, while Hall sensors monitor the three indicator positions: DOWN, UP and 1/2.

The video also shows the landing gear indication during the transition between the different gear positions.
