Responsibility for supervising all airside activities is assigned; arrival procedures before the aircraft reaches the stand ensure the ramp is inspected and free of FOD and obstructions, GSE positioned clear and personnel ready, and after stopping ensure chocks, cones, engine run-down and clearance before approach; procedures govern opening and closing cabin access doors; departure procedures ensure the ramp is clear, GSE removed, doors and panels closed, and a walkaround inspection immediately before departure confirms the aircraft's condition; pushback and towing procedures ensure suitable equipment, communication with the flight deck and clearance; and adverse weather procedures should cover slippery aprons, thunderstorms, high winds and other conditions (GRH 3.2.1 to 3.2.10).
