How does an airport catering truck work? The process starts with loading pre-portioned meals, beverages, and utensils—stored in insulated trolleys—from airport catering kitchens. The truck’s temperature-control system maintains 2–8°C for cold items and 60°C+ for hot food to meet safety standards. Upon reaching the aircraft, its hydraulic lift adjusts to match the plane’s service door height (1.8–4.5m). Staff secure the truck to the aircraft via locking mechanisms, then roll trolleys onto the plane through a retractable bridge. Post-flight, it returns to collect used trolleys, completing the closed-loop service efficiently.
