PBBI with full unit tilt correction and flexible floor extension minimizes the exerted force in contact with aircraft and conforms to all normative standards.
The PBB will be stopped by the drive unit with safety distance to the aircraft avoiding any contact and therefore damages to the fuselage.
Driven by gas pressure springs the flexible floor extension will be pushed out. Only a minimum pressure will be applied to the fuselage.
PBBI is the most safest and comfortable floor for a bridgehead.
