FLYING THE NAVION on the VOR approach
into Tullahoma Regional Airport (THA)
that day in 2004 took all the concentration I could muster. Despite constant pitch
corrections, I just couldn't seem to get it
right. I felt as though I were more along
for the ride than in control of the airplane.
After witnessing several minutes of my
struggle, Rich Ranaudo, my colleague and
mentor in flight testing at The University
of Tennessee Space Institute, suggested I
freeze the yoke, note the aircraft reaction,
and then use smaller and more selective
inputs. Sure enough, it worked, and I completed the approach.
The technique of freezing the yoke to
remedy a pilot-induced oscillation was new
to me. Having already earned commercial
and flight instructor certificates, I wondered how I could have missed this great
advice. I searched my training textbooks
to no avail. Then I queried my friends. Any

relief I may have felt after realizing that
I wasn't alone in this regard gave way to
incredulity at our communal ignorance.
The FAA defines loss of control as an
"unintended departure from controlled
flight." While the term might elicit notions
of stalls, spins, and upsets, flight situations such as pilot-induced oscillations fit
the definition as well. Each of these events
deserves more attention in primary and
recurrent training.
STABILITY

Stability is the most basic autopilot with
which an airplane is constructed. A stable
airplane will return to its trimmed condition (equilibrium) upon a disturbance.
As student pilots, we were taught to set
the pitch trim tab to ease our workload
in longitudinal control. Upon an unexpected deviation in angle of attack, the
airplane will naturally seek its equilibrium.
