AIRPORT PLANNING MANUAL 5. TERMINAL SERVICING During turnaround at the air terminal, certain services must be performed on the aircraft, usually within a given time to meet flight schedules. This section shows service vehicle arrangements, schedules, locations of servicing points, and typical servicing requirements. The data presented herein reflect ideal conditions for a single aircraft. Servicing requirements may vary according to the aircraft condition and airline operational (servicing) procedures. This section provides the following information: • The typical arrangements of equipment during turnaround; • The typical turnaround servicing time at an air terminal; • The locations of ground servicing connections in graphic and tabular forms; • The typical sea level air pressure and flow requirements for starting the engine; • The air conditioning requirements; • The ground towing requirements for various towing conditions. Towbar pull and total traction wheel load may be determined by considering aircraft weight, pavement slope, coefficient of friction, and engine idle thrust.
