"Prophecy of Wilbur" Foresees Big Boost to Aviation Efficiency
GIBRALTAR, 13 December, 2016 - "The Prophecy of Wilbur," an account of aviation history
recently unearthed near Kitty Hawk, North Carolina, tells how aviation has lifted mankind
above the primordial ooze with great reliability.
Commercial aircraft perform wonderfully at 35,000 feet, but while aircraft are highly safe
and efficient in the air, they are much less efficient when operating on the ground. At a
conference in London last week, airline executives learned of a significant opportunity to
improve efficiency between flights.
In a presentation to the Marketforce Future of Air Transport conference, the "Prophecy of
Wilbur" revealed that the next big advances in aviation will come from ground operations,
through faster and more efficient turnarounds between flights. Onboard electric drive
systems will enable airlines to reduce costly ground times between flights, reduce
schedule uncertainty, and boost aircraft productivity and profitability.
Airline executives learned that the new WheelTug® technology will enable a consistent
gate pushback time of just 1 minute, thereby allowing scheduled flight turnaround time
to be reduced by as much as 20 minutes.
Reporting on recent analyses of multiple airlines' performance, WheelTug CEO Isaiah Cox
told conference attendees that the average flight requires 8 minutes from "ready for
pushback" to forward motion. But the inefficiencies and scheduling uncertainties of that
timing are even further-reaching: to ensure that at least 98% of flights achieve forward
motion on schedule, airlines effectively budget 20 minutes for pushback.
By reducing complexity and uncertainty in ground operations, Mr. Cox explained that costly
aircraft ground time can be sharply reduced, scheduling can be tightened, and in many cases
an aircraft can make an additional flight per day, providing a considerable productivity boost.
Recent studies at several airports have found that most commercial airlines cannot reliably
accomplish a gate turnaround in less than 40 minutes. But the WheelTug system can create new
and significant time-saving opportunities beyond the traditional gate turnaround metric. By
simplifying and speeding pushback and initial taxi operations, WheelTug can save up to 20
minutes per flight. The reduced complexity and greater predictability, he said, will allow
for tighter scheduling, greater passenger capacity and aircraft productivity, and greater
airport throughput capacity.

The WheelTug onboard aircraft electric drive system is expected to save airlines from 7 to
20 minutes per flight depending on the extent of utilization. In addition, it will reduce
costs, including engine maintenance and repair, brake wear, injuries, and fuel. Overall,
the WheelTug system is projected to save well over $1 million per plane per year. The
initial version for the Boeing 737NG family is expected to enter service in 2018, with
an Airbus 320 version to follow thereafter.
