ISO 7718-1:2016

Aircraft - Passenger doors interface requirements for connection of passenger boarding bridge or passenger transfer vehicle - Part 1: Main deck doors

ISO 7718-1:2016 specifies minimum requirements for dimensions and unobstructed space around main deck passenger doors of future types of civil-passenger transport aircraft when they are intended to be compatible with the thousands of passenger boarding bridges and passenger transfer vehicles existing, or being planned, in airports worldwide. ISO 7718-1:2016 is not applicable to existing models of civil transport aircraft, or derivative models with entry into service up to year 2000 with the same fuselage, for which the aircraft-mating section of passenger boarding bridges or passenger transfer vehicles is expected to be compatible with ISO 16004. It is not the intent of this document to restrict in any way the basic design of any future types of civil-passenger transport aircraft. However, it aims at clarifying, for aircraft-design engineers, the design characteristics which would make it difficult or impossible for a new type of aircraft to adequately connect with existing airport passenger boarding bridges or passenger transfer vehicles. If basic aircraft-design requirements impose on a future model certain dimensional characteristics not complying with this document, note that: - either alternative methods of embarking/disembarking passengers will need to be implemented, such as integral aircraft stairs, etc.; - or existing passenger boarding bridges and/or passenger transfer vehicles in the airports where such a new type of aircraft is to operate will require some degree of modification/reworking; - or additional interface devices/equipment will be required in order to connect such a new type of aircraft with existing passenger boarding bridges and passenger transfer vehicles. Each case results in increased aircraft-handling constraints and operating cost.

Overview

ISO 7718-1:2016 is an international standard developed by ISO that specifies the interface requirements for main deck passenger doors on civil transport aircraft. This standard focuses on ensuring compatibility between aircraft doors and passenger boarding bridges (PBBs) or passenger transfer vehicles used at airports worldwide. It defines minimum dimensional and unobstructed space requirements for new aircraft types to facilitate safe and efficient passenger boarding and disembarking.

The standard applies primarily to future civil-passenger transport aircraft models and is not intended for existing aircraft or derivatives with entry into service before the year 2000, which are generally compatible with ISO 16004. The goal is to avoid costly modifications to aircraft or airport infrastructure by guiding aircraft designers on critical dimensions and door characteristics.

Key Topics

• Minimum Unobstructed Space
  The standard mandates a clear area surrounding the main deck passenger doors to allow hassle-free connection with boarding bridges and transfer vehicles. The space must be free of external obstructions such as antennas, sensors, and aerodynamic features that could interfere with the docking process. Integral aircraft stairs are permissible if they do not impede the boarding bridge connection.

• Fuselage Radius
  The cross-sectional radius of the aircraft fuselage at the door area should be no less than 1.6 meters (63 inches). This dimension ensures sufficient clearance for the interface with boarding equipment.

• Door Sill Height
  The height of the door sill above the ground must be between 1.8 meters (71 inches) and 5.4 meters (213 inches) during normal servicing operations, accommodating a wide range of boarding bridge designs and airport layouts.

• Compatibility with Existing Infrastructure
  The standard emphasizes avoiding design features that would hinder compatibility with existing passenger boarding bridges and transfer vehicles. When deviations occur, alternative boarding methods, costly airport equipment modifications, or additional interface devices may be necessary, leading to increased operating costs.

Applications

ISO 7718-1:2016 is essential for:

• Aircraft Manufacturers and Design Engineers
  Provides clear dimensional guidelines that help avoid interface issues during aircraft development, ensuring future aircraft can easily connect with the global network of airport boarding equipment.

• Airport Planners and Operators
  Helps anticipate and manage the compatibility of new aircraft types with existing passenger boarding bridges and transfer vehicles, enabling smoother ground operations and minimizing retrofitting expenses.

• Ground Handling Equipment Designers
  Serves as a reference to design passenger boarding bridges and transfer vehicles that meet interface requirements for current and future aircraft models.

• Regulatory Bodies and Certification Authorities
  Supports the establishment of uniform requirements for safe and efficient passenger boarding procedures in civil aviation.

Related Standards

• ISO 16004 - Specifies interface requirements between passenger boarding bridges or transfer vehicles and aircraft doors for legacy aircraft models, particularly those in service before 2000.

• ISO/IEC Directives - Outline the procedures for developing and maintaining international standards which ensure quality and consistency in documentation.

By aligning with ISO 7718-1:2016, stakeholders in civil aviation can achieve better interoperability between aircraft and airport ground equipment, reducing operating constraints and enhancing passenger experience. The standard is a critical resource for fostering innovation while maintaining practical compatibility across the aviation industry.
