Passenger boarding bridges (PBB) / jet bridges · clarifiers
A passenger boarding bridge is twenty-year fixed airside infrastructure — the wrong spec strands a gate for its whole service life. Before any supplier can quote, we need the aircraft envelope and the stand geometry it has to fit (this decides which bridge types are even eligible), the tunnel and drive configuration, the integrated airside utilities the gate expects the bridge to carry, the GCC-climate cooling load, and the standards regime it must certify to. These are the engineer-grade clarifiers a terminal planner would ask — not a generic enquiry form.
What aircraft must this bridge dock, and what's the stand geometry it has to fit — apron-drive or fixed/nose-loader?— unblocks quoting This is the one fact that decides which bridges are even eligible. Aircraft mix sets the reach and door-sill envelope (a Code C narrow-body gate and an A380 upper-deck gate are different machines), and the existing stand — apron-drive bogie sweep vs a fixed nose-loader pivot — determines whether a self-propelled bridge can reach the doors at all. A nose-loader stand can't accept an apron-drive bridge and vice versa, so getting this wrong invalidates the whole quote.
Select… Narrow-body only (A320/B737, ICAO Code C) — apron-drive stand Mixed narrow + wide-body (up to B777/A350, Code C–E) — apron-drive stand Wide-body incl. A380 main + upper deck (Code F, dual/triple bridge) — apron-drive stand Regional jets / turboprops (low door-sill, ATR/Dash 8/E-Jet) Fixed / nose-loader stand (telescopic, no apron travel) Greenfield stand — geometry not yet set, need advice Bridge type and tunnel construction? Drive type and tunnel material set both the price band and the lifecycle behaviour. Apron-drive bogie bridges sweep a wide apron and serve a diverse fleet but cost more; fixed/nose-loader and T-bridges have fewer moving parts and lower servicing. Glass-panel tunnels give the premium daylight terminal feel but admit solar heat (a real cooling penalty in the Gulf); steel and corrugated-steel are cheaper and more robust. Suppliers quote different platforms entirely depending on this.
Select… Apron-drive, glass-panel tunnel (premium / panoramic) Apron-drive, steel-panel tunnel (robust / lower cost) Fixed nose-loader or T-bridge (telescopic, fixed position) Dual / triple bridge per stand (MARS / wide-body high-capacity) Over-the-wing / second-level (aft-door simultaneous boarding) Not sure — recommend based on the stand Which integrated airside utilities must the bridge carry? PBBs are increasingly bought as the integrated services point at the gate, not just a tunnel. 400 Hz ground power, pre-conditioned air (PCA), potable water and a Visual Docking Guidance System are each separately specified options that change the supplier's bill of materials, the structural loading and the price materially. Naming them up front avoids a re-quote and tells us whether the supplier needs PCA/GPU partner integration.
Select… Full suite: 400 Hz GPU + PCA + potable water + VDGS 400 Hz GPU + PCA only VDGS / docking guidance only Bridge only — utilities supplied separately Not sure — advise on the standard GCC gate fit-out GCC-climate cooling expectation — how is the bridge/PCA sized for the heat? Gulf apron temperatures and large glazed tunnel areas drive the cooling load that defines PCA capacity and tunnel insulation. A bridge sized for a temperate hub will under-cool an A380 sitting at a 50°C stand. Suppliers offer insulated steel walls, thermal glazing and uprated PCA specifically for this — the climate answer changes the canopy fabric temperature rating, the PCA tonnage and the tunnel wall build.
Select… Extreme heat — uprated PCA + insulated/thermal tunnel required Hot, glazed tunnel — need solar-load mitigation Standard climate sizing is fine Don't know — size it for a Gulf hub by default Docking and operating mode? Docking mode spans manual operator control, semi-automatic one-push VDGS/APIS docking, and full AI camera auto-docking to ~10 cm — a spread that changes the control system, operator training burden and price by a wide margin. It also flags retrofit-vs-new: an automated docking system (e.g. JetDock-class) can be retrofitted to an existing bridge, which is a different quote from a new automated bridge.
Select… Manual operator docking Semi-automatic — one-push VDGS / APIS docking Full AI auto-docking (camera, no fuselage markings) Retrofit automated docking onto our existing bridges Open — recommend for our traffic level Which standards and local CAA approval must the bridge certify to? PBB compliance is built from layers, not one law — ICAO Annex 14 aerodrome design, AWS D1.1 structural welding, NFPA 415 / DIN 5510 canopy and tunnel fire ratings, and ISO 9001/14001 factory quality, all under the destination GCC regulator's approval (GCAA, GACA, QCAA). A supplier who can't evidence the right fire standard and the local CAA acceptance pathway can't be shortlisted, so we capture the baseline before quoting.
Select… ICAO Annex 14 + NFPA 415 canopy fire + AWS D1.1 weld + ISO 9001 EN / DIN fire standards (DIN 5510 / NF F 16-101) + ISO 9001 GCC CAA approval required (GCAA / GACA / QCAA) — specify which Match our existing fleet's certification baseline Not sure — list the standards a GCC hub will require Optional — these help the supplier quote accurately first time (condition, certification and delivery especially).
