LEIGH CAULFIELD

I thoroughly enjoyed reading
the history and development
of our aviation charts as covered in " Our Printed History. "
While not having any of these
documents, I confess to having
a temporary radiotelephone
operators permit dated April
1973 in my flight bag. This
document was required of all
pilots wishing to use radio
communication. This too is
a throwback to another time,
or more specifically, another
millennium!

IN CALLING BULLSHIT: The Art of Skepticism
in a Data-Driven World, scientists Carl
Bergstrom and Kevin West discuss black
boxes, scientific methods complicated
enough to make independent verification
of the output difficult or even impossible
by members of the general public. Medical
researchers tell us that a glass of wine each
day promotes good health. They justify the
statement using appropriate scientific and
statistical processes from their impressive
education. For those of us without that
training, the techniques constitute a black
box. If we trust the researchers, we drink
up with confidence. If what they advocate seems too good to be true, we call BS
and investigate further before pouring yet
another glass of pinot noir.
What do black boxes and calling BS
have to do with flying airplanes? More
than you might imagine.
On a recent practical exam, my candidate Penny shared an instrument flight

she had planned from Mesquite, Nevada,
(67L) to Burbank, California (BUR). Like
many instrument rating candidates, she
completed all flight planning items using
the software on her tablet. The scenario
that day involved a 200-foot ceiling over
Mesquite so Penny planned to obtain her
clearance on the ground and incorporated the obstacle departure procedure
in her plan. When asked the fuel quantity
required for the trip, Penny related a value
that seemed so preposterously low my BS
alarm blared in my head.
" Are you sure about that? "
" Well, that's what the software is telling me, " she responded. I suggested we
pull out the aircraft operating handbook
and verify the results.
It soon became evident Penny didn't
understand how to use the performance
charts, and that's a big problem. By her
inability to verify the results, the fuel calculation algorithm had become a black

seen by many-the view from a
general aviation aircraft.
AOPA believes that Black
lives matter but does not support any one political stance
or organization. We regret
including the photographer's
personal views on the protest
in the story.

HANGAR TALK

Hanging out on a farm on a beautiful day is just one of the perks of working for AOPA-we really never know where our stories will take us. Senior
Photographer CHRIS ROSE is an avid outdoorsman-he fly-fishes, hunts,
hikes, and metal detects in the natural world around AOPA headquarters
in Frederick, Maryland. While many may think that AOPA's proximity to
Washington, D.C., means Frederick is the " big city, " we are surrounded by
farmland, historic battlefields, and rivers and streams. It was nice to get even
more out of town to Stafford County, Virginia, to meet DC Aerial Photos owners Susan and Dan Hedenberg, who live on a 40-acre farm complete with a
grass airstrip. The dichotomy between where they live-rural farmland-and
where they work-the nation's capital-is intriguing, made even more so by
the access general aviation affords. Washington, D.C., traffic even on a good
day means hours spent in a car from both Frederick and Stafford County,
but a short, beautiful flight. Read " FARM TO CAPITAL, " beginning on page 60.
Pilots love to personalize their aircraft, and balloon pilots are no different.
Patrick Smith, the pilot in " LIGHT THE FIRE, " p. 68, has three balloons-and
each one's N number includes the initials and birth dates of his three children:
Lylah James; Levi Rend Patrick; and Lucie Blaire Emberlynn. Smith and his
wife, Meagan, are expecting a fourth child in June; no word yet on whether
this baby will get his or her own balloon as well.
