Abstract: An observation system for an aircraft, related aircraft and method are provided. The observation system includes an observation assembly deployable between a retracted inner position and a deployed outer position outside a passage opening and a deployment mechanism of the observation assembly. The system includes a hatch, mounted moving between a position closing off the passage opening and a position clearing the passage opening, and a mechanism for maneuvering the hatch between the closing off position and the clearing position. The system also includes a conjugating assembly between the mechanism for deploying the observation assembly and the mechanism for maneuvering the hatch, active over at least part of the movement of the observation assembly between the retracted position and the deployed position, to move the hatch from the closing off position to the clearing position during the movement.
