Pitch,
Roll & Yaw

“Isn’t
it astonishing that all these secrets have been preserved
for so long so that we can discover them?”
Orville Wright, Kitty Hawk, 17 December
1903

The
secrets that Wilber and Orville uncovered in their four years of
glider and manned flight research and experimentation at Kitty Hawk,
Outer Banks, North Carolina were Pitch, Roll and Yaw.
Pitch is the aviation term for the
nose of an aircraft going up or down. The Wrights designed
elevators that controlled the longitudinal axis. Roll is the term
for the aircraft rotating around its horizontal axis to make
turns. The French word ailerons describe the controls for roll.
And Yaw is the term for the nose of the aircraft rotating
around its verticle axis. Orville and Wilbur built rudders on
their Wright Flyer to achieve needed yaw. Their invention of
this fundamental “Three-axle control” enabling a pilot to steer the
aircraft in equilibrium was their historic breakthrough that
overcame the flying problem.

For the one hundred and six years,
since Wilbur and Orville flew 120 feet in 12 seconds on the first
manned aircraft flight, every airplane, glider, missile and space
ship has been designed around the need for controlling pitch, roll
and yaw to fly successfully. Fifty years after the Wright’s
historic flight I made my first flight at Marana, Arizona in a
propeller driven Air Force T-6G Texan basic trainer. My Flight
Instructor made sure I fully understood pitch, roll and yaw before
he cleared me for solo flight on 8 January 1953.
How astonishing it is that these
secrets of human flight remained undiscovered for centuries of
humans dreaming of flight from the Greek mythology of Daedalus
to Michelangelo (1475-1564) and to 19th Century failed
flight attempts. Pitch, Roll and Yaw are the quality classics of
flight proven in 1903. They will remain essential forever.
What is the lesson of the Wright’s
discoveries for the Quality Sciences? Are there still secrets to
be discovered? Since the Quality Control pioneers began the
movement after World War II quality has gone global, has
revolutionized manufacturing and much of management. The Inland
Empire, Riverside, California ASQ Section 0711 web site, has a
summary of the classic approaches and tools that did it (www.asq711.org).
A Google search on 23 December 2008 for “Quality Control” produced
73,200,000 hits, for “Quality Management” 79,100,000 hits and for
“Quality Sciences” 20,500,000 hits. After 50 years ASQ is now the
Global authority for doing more with less. An impressive story?
Yes.
But the story
is not over. There is increasing evidence that the quality of
life for humans on Earth has huge variance. It is not
necessarily on a continual improvement track. There exits in
2009 a deep crevasse between those areas where Quality has become
imbedded to those areas where ignorance, need and want are the
stepping stones to future catastrophes. There may not be another
50 years to solve the problems of continual war and global
poverty undermining progress (since
the 2000 millennium world military expenditures have risen annually
from 800 billion to 1.2 trillion dollars) , of energy needs
outstripping current projections, of the pollution of Earth’s
environment, of terrorist killings, of hundreds of millions of people
without clean drinking water, of disease pandemics, of continued
population rise, and of poor or ideological-based education. The
stability and sustainability of global civilization is threatened. Our
100,000 ASQ members are the logical ones to lead in uncovering
the secrets to solve those problems.
I submit that there are three
quality secrets waiting discovery and implementation. They are:
-
Fixing the
existing incapacity to create ethical Governance.
-
Reducing
the increasing high percentage of World military expenditures which
creates the potential for mass killing
or even human extinction and consumes resources for other needs.
-
Creating
Social Responsibility within global communities for people’s needs.
Just how these three secrets can be
discovered and implemented remains a challenge for the increasingly
international scope of the American Society for Quality (ASQ).
