ISO 7718-1:2016

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.
