In a test for an American TV science programme, the Steffen Method halved the time spent boarding using conventional systems.
Michael O'Leary, the chief executive of Ryanair, expressed interest in the concept: "We will always look at anything that would improve our 25-minute turnarounds or our No 1 punctuality," he said.
At present the airline sells "priority boarding" at £5 a time to a maximum of 90 passengers per flight.
On airlines that use assigned seating, the standard means of boarding is to call passengers by block: row 21-30 in a narrow-bodied jet, followed by rows 11-20 and 1-10.
But tests conducted in a mock-up of a section of a Boeing 757 showed this method took 414 seconds - almost seven minutes - and was the least efficient of those tested.
Dr Steffen told The Independent: "I was surprised that 'block boarding' did so badly. I was expecting it to be closer to the time of random boarding. I didn't account for seat interferences, assuming them to be relatively less important than aisle interferences."
Evidently the impediment to smooth boarding is other people - plus their awkward luggage, a result of financial penalties for checking in bags.
A more sophisticated variant, in which passengers are boarded strictly by row from the rear of the aircraft, was significantly quicker at 371 seconds. Yet an entirely random boarding pattern with no assigned seats, as practised by many budget airlines, scored much better at 284 seconds - almost one-third quicker than "full-service" carriers with pre-assigned seats.
The Steffen method enabled all passengers to be boarded and seated in just 216 seconds, a rate of three seconds per person. Applied to a typical 180-seat no-frills aircraft, this radical approach could slice nine minutes off the time each aircraft spends on the ground. Over a year, this could save two weeks - worth £1m - per plane.
