"Hybrid propulsion systems [those that
pair internal combustion engines with battery power] will play a role in the interim, but
these systems are complex. They're doable,
but in 20 years we should have all-electric
designs with similarities to, say, a Beech
Bonanza in terms of speed, range, endurance,
and load-carrying ability," Bye said.
He's not as sanguine about eVTOL technology's future. "Their ducted fans are only
efficient in the vertical phase of flight, but
they create a lot of noise, and weigh a lot, and
create a lot of drag in horizontal flight," he
said. "Also, their many design concepts-with
some having articulating wings and multiple
engines-have yet to be proven. As with helicopter technology, eVTOLs may eventually
become practical, but it will take time."

THE
MISSING
INGREDIENT

The culture shift necessary
to develop next-generation
urban travel

DAVE VOS

BY THOMAS B. HAINES

D R O N E S, U R BA N A I R T R A N S P O RT S,

eVTOL-whatever you call the nextgeneration vehicles that will supposedly
whisk urban dwellers around a metropolitan region-face many challenges, but it
may not be the challenges you think. The
electric motors, the batteries, and the
technology to control such aircraft exist
today. Sure, improvements must be made
to increase performance, especially with
batteries. But the real challenge, according to technology expert Dave Vos, is
the ability-or willingness-of software
developers to quickly learn what the aviation and aerospace industry has
struggled with for more than 100
years-demanding a level of
reliability and redundancy
that is safe right out of
the box.
"The tech world has
so much to learn about
safety and reliability. The
culture that you have a
solid review process-that's
missing," said Vos. "Yes, you
need to be efficient and nimble, but there is no substitute
for the disciplined process
that aviation and even bridge
and tunnel designers have
used for years. There's really
only going to be one winner,
and that is safety. You can't just
hit the compile button and go try
something, and figure you'll fix the
problems later, when you're dealing
with people's lives."
Vos is the co-founder of Athena
Technologies, a Virginia company that
developed flight control systems for
large military drones. After selling that
company to Rockwell Collins, he moved
to Google to run its Project Wing program-the outfit that used drones to
deliver 1,000 Chipotle burritos to students on the campus of Virginia Tech.
He has since left the tech world to run
his horse business.
If the software developers can make
the culture leap, Vos believes that drones
will get full certification for delivery purposes within the next five years, which
will be a watershed moment for future
