The reason why your spoilers and flaps no longer register the axis is because the throttle takes into account all of the axis’s positions when you calibrate. So if you’re only moving the throttle, and not moving the spoilers and flaps, the throttle will take those static positions as the calibrated positions.
So when you calibrate with the addons attached. You have to calibrate the spoilers and the flaps at the same time with the throttles… So:
- Throttle at TOGA, Spoilers Up, Flaps Up -> Press Red Buttons.
- Throttle at MCT, Spoilers 1, Flaps 1 -> Press Red Buttons.
- Throttle at CLB, Spoilers 2, Flaps 2 -> Press Red Buttons.
- Throttle at IDLE, Spoilers 3, Flaps 3 -> Press Red Buttons.
- Throttle at full REVERSE, Spoilers Full, Flaps Full -> Press Red Buttons.
Once that’s done press the two black buttons to complete the calibration process.
