Abstract
A mobile passenger ramp for loading and unloading aircraft, the ramp comprising having upper and lower frame sections connected pivotally so that the ramp can be folded for storage or movement about the tarmac and unfolded at an obtuse angle to form a wide 'footprint' to provide wind or jet blast stability. An arcuate surface bridges between the ramps of the two frames when unfolded. The compact ramp remains safely clear of a 'No-Go' zone while still being sufficiently long to minimize the slope of the ramp for improved ease of use by passengers, either ambulatory or in wheelchairs. A steerable wheel at one end of the ramp enables rotation of one frame about the pivoting connection for folding and unfolding the frames. Fixed wheels on the upper frame and a castored wheel positioned near the pivot point on the lower frame provide stability and easy maneuverability of the folded ramp.
