DENSITY ALTITUDE AND SEDONA
AVOID THE HEAT OF THE DAY
IMAGINE YOURSELF AMONG THE RED
rocks of Sedona, on final approach for
the legendary plateau airport at 4,831
feet of elevation. Not too high, relatively
speaking-but with temperatures soaring
into the 100s in the summer, the air
can be mighty thin. If you fly in without
considering density altitude, you may be
in for a rude and rough awakening.
Density altitude is pressure altitude
corrected for nonstandard temperature,
also known as the altitude that the
airplane thinks it is flying. The thinner
air means the engine has fewer air molecules
to work with, thus creating less
thrust, and the wing and other control
surfaces have less air to make lift. Combine
these two facts and you can end up
with a deadly combination of an underpowered,
underperforming airplane.
Here are some considerations for
flying and landing at lofty heights.
JUST BECAUSE YOU CAN LAND DOESN'T
MEAN YOU CAN TAKE OFF. Don't take
off on a hot afternoon without a solid
understanding of how elevation and
heat will affect your takeoff roll.
Even if you can take off, you might
not be able to outclimb the surrounding
terrain. Watch ASI's Accident Case
Study: Into Thin Air to learn more about
the hazards of high terrain and density
altitude-two factors that often go hand
in hand, especially west of the plains.
YOU CAN'T TURBOCHARGE A WING. " My
engine is turbocharged! " you say. But
even if your airplane's engine can adjust
to the higher altitude, its limited and
unchanging wing surface can't.
REMEMBER THE POH WAS CREATED BY
TEST PILOTS IN BRAND-NEW AIRPLANES.
Pad those performance numbers from
the pilot's operating handbook and
factor in at least a 25-percent increase.
Fifty percent would be safer, especially
if you're new to high DA ops.
A temperature of 100 degrees Fahrenheit/38
degrees Celsius can make Sedona's 4,831-foot
elevation feel like close to 8,700 feet. Some
electronic flight bags calculate density altitude
and display it with the METAR for a given airport;
you also may calculate it using an E6B.
