Low-level loading bridge

Transportation Development Centre

Objective
To design, develop, and demonstrate a low-level loading bridge (LLLB) for boarding passengers in wheelchairs onto small commuter aircraft.

Description
This project is based on earlier TDC work that developed the concept and indicated the feasibility of using an LLLB with small aircraft.

The contractors defined specifications, drew up a detailed design, and then constructed a prototype loading bridge. After functional testing, the prototype was modified to correct the shortcomings indicated by the tests.

Results
A one-year technical and ergonomic evaluation in service at Ottawa International Airport led to further improvements. The bridge now meets both the Canadian and the Americans with Disabilities Act standards for barrier-free access. It features:

  • compatibility with a broad range of small aircraft
  • integrated boarding for all passengers
  • full shelter from the elements
  • smooth transitions with no stairs or other barriers
  • changes in floor covering to give tactile clues to differing ramp angles
  • bevelled edges on ramps and sills
  • contrasting lighting
  • well-placed hand rails
  • temperature control

The bridge is in use in Edmonton and at several U.S. regional airports.

For optimal cost-effectiveness, purchase of the bridge should be factored in to plans for airport upgrades or renovations.
