known that attacks of vertigo
can be induced by sudden head
movement when pilots are flying
in IMC conditions. A vertigo
attack may also occur in the
passenger cabin, as described by
this Flight Attendant’s report to ASRS:
Approximately 1 hour into flight, I started feeling a bit
strange – it was really bumpy and with the combination of
that and a bad headache, I decided to sit down. As soon
as I tried to stand up and keep working, I became
extremely dizzy and couldn’t stay standing. My purser
knew I was experiencing vertigo, so he paged for a doctor.
An emergency room doctor responded. The purser got
oxygen and an enhanced medical kit. After about 1 hour,
the doctor suggested that he give me two injections for
nausea and dizziness… The doctor was wonderful. He sat
on the floor and held my hand for hours.
Flight attendants should be educated about vertigo. I didn’t
know that the ear infection I had could end up becoming
such as horrible, maddening experience!
A B767 Captain filed a report about a different type of
vertigo that can be induced on the ground or in the air.
While doing [the] pre-flight walkaround, I had to shade
my eyes from a very bright yellow strobe. This strobe was
on top of the fuel truck, about head level high. All the fuel
trucks have them and they cannot be turned off. The ramp
agents were also blinded by the brilliant flash and had to
walk with their heads turned away to avoid being blinded /
disoriented by the flash. This could cause ‘flicker vertigo,’
nausea, or temporary blindness. The ramp area around
aircraft is the most dangerous on the airport and this is
potentially a very bad addition to the danger…
“Flicker vertigo” is a term that describes an imbalance in
brain cell activity created by light sources that emit a
flickering rather than steady light. Light flickering from
4 to 20 times per second can produce dangerous and
unpleasant reactions in some people, including nausea,
dizziness, migraines, unconsciousness, and even epileptic
seizures.
Both natural and artificial light sources – especially
florescent lighting and television screens – may
precipitate flicker vertigo. In aviation operations,
problematic light sources include windmilling propellers
that cut the sun to give a flashing effect, and rotating
beacons or strobes in certain lighting and atmospheric
conditions.
Chapter 8-1-5 of the Aeronautical Information Manual,
Medical Facts for Pilots, offers a comprehensive
discussion of other illusions of motion and position.
Information Sources for Airspace NOTAMS
The November CALLBACK carried an article on
Enhanced Class B airspace and cited the internet
address of the FAA web site where information on the
most recent airspace changes can be found:
http://www.faa.gov/apa/update.htm
A CALLBACK reader reminded us that additional upto-
date airspace information is available from several
aviation organizations. The Aircraft Owners and Pilots
Association (AOPA) offers updated airspace information
on its Home Page, and will send members a
personalized e-mail alert notifying them if airspace
rules change within 250 miles of their home airport.
The AOPA web site address is: http://www.aopa.org.
The Experimental Aircraft Association (EAA) and
National Business Aircraft Association (NBAA) also
offer updated airspace information at
http://www.eaa.org and http://www.nbaa.org,
respectively.
Pilots using internet sources for NOTAM information
should be aware that the information is subject to
constant (even daily) changes. It is extremely important
that all pilots check with Flight Service for applicable
NOTAMs prior to every flight.
Uninvited
The Captain of a corporate jet narrowly avoided an
airspace intrusion when complacency and a “let’s get
home” attitude set the stage for a rushed departure:
After a quick stop for fuel, luggage and passengers,
we were on our way. Took off VFR, contacted Approach
for the IFR clearance. Controller’s first instructions were:
“Stay out of the Class C airspace, squawk XXXX.” I
missed the Class C airspace by climbing and turning.
Approach gave me the IFR clearance, cleared me into the
flight levels, and we had an uneventful trip the rest of the
way home…
Complacency and being in a hurry were factors leading
to this situation. I had the enroute chart out and folded
to the general area, but didn’t take the time to review it
before takeoff. I just assumed there was nothing in my
