Friday, November 19, 1999 10 AM - 11 AM Pacific
Ray Oyung, Research Coordinator for the Fatigue Countermeasures Program

Ray Oyung is part of a team that tries to find ways of reducing the
effects of fatigue, sleep loss, and disruptions to the body's internal
clock on flight crews during flight operations.

The Aerodynamics of Things That Spin

A WebCast /Chat from NASA Ames Research Center
 featuring Dr. Earl Duque and Joe Jordan

Wednesday, December 1, 1999, 10 AM PST

Join us for a fun-filled hour of demonstrations, videos and explanations
about things that spin.
You can ask questions in the chat room and Earl and Joe will answer
them. Dr. Duque is a research scientist who uses computers to study the
aerodynamics of helicopters, rotorcraft, and wind turbines.
They will discuss how nature and humans have designed spinning devices
to fly through the air, generate energy and dry your hair.

this event.

[Editor's Note: Ray Oyung, is a researcher here at NASA Ames Research
Center, studying how to keep pilots from getting too sleepy. Read his

Our group just completed the data collection phase of another study in a
Boeing 747-400 simulator. For those of you who have been following along
with me, this study is similar to the night time study that our group
completed last year...and you know what that means. [alarm sounds] "Whoa,
4:00 pm. Time to wake up and have some breakfast. I think I'll make a
sandwich and grab some Campbell's Chunky Chicken Noodle soup for my lunch
at midnight." (people tell me I think with my stomach but I don't think so

For those of you who are just tuning in, our program conducted a study
with commercial airline pilots to determine if having five breaks during a
long overnight flight would help keep pilots more alert than pilots having
only one break. The answer seemed obvious enough and preliminary results
showed that breaks do seem to help, but prior to our study, reports have
only been noted on what pilots say they feel during these types of trips.
We used electrode sensors (no I don't have a hunched-back helper named
Egor), fill-in the answer type questions, reaction time tests, and other
devices to determine if multiple breaks during a flight really help. For
more background on this past study, you can review these articles from my
journal, Alertness Measures Effectiveness Study, July 4, 1998 and Planning
a Simulator Study, February 11, 1998.

Our study this year looked at how well an alertness monitoring device
works with pilots on the flight deck. Wouldn't it be nice to have someone
talk to you or remind you to do something when you were tired and might
forget something you needed to do? We had the opportunity to find out if
this type of device might help pilots while they were flying for long
periods at night.

The system is camera based, and a computer would watch the pilot and see
if he/she is tired. If the computer thinks the pilot is tired, it will
give the pilot an indication on a lighted panel or by voice command
through the headset that pilots wear while flying. The device we used was
in its early stages of being so we're not sure what to expect.

Do you think something like this would help pilots? Stay tuned to find

Wow...10 days till Halloween! Have fun, but be safe and watch out for
things that go "thump" in the night...boo! :-)
