A WING FLYING AT A HIGH ANGLE OF ATTACK creates a large turbulent air zone behind the

wing. Lowering the angle of attack minimizes the resulting drag.

THE SECRET OF FLIGHT BY ALEXANDER LIPPISCH, UNIVERSITY OF IOWA

to learn more.

From what I see on single-engine
practical exams, the same can't be said
for single-engine candidates. Often on
failing the engine, the candidate immediately looks around at the surrounding
terrain while letting the airspeed wander
on an airplane that still features all sorts of
unnecessary drag. I wonder why we don't
hammer home engine-out procedures the
same way for all pilot training. The typical procedure for a single-engine airplane
differs slightly from that above:
1. Achieve and maintain best glide
airspeed in order to increase control
effectiveness and roll stability as well as
minimizing the descent angle. Immediately
following takeoff, this will require pushing
on the yoke.
2. While identifying and steering the aircraft gently toward favorable terrain, clean it
up aerodynamically by retracting the gear,
flaps, and cowl flaps. With the inoperative
engine obvious, pull the propeller control
back to allow for minimal rpm and maintain coordinated flight.

3. Only if time and altitude permit,
attempt to diagnose and remedy the
problem.
Now, stopping a fixed-pitch propeller of
a single-engine aircraft is more of an academic exercise than a practical one. But
those tests with Bill indelibly impressed
the importance of remembering to minimize propeller drag if I am able.
Most of the common items, including
the initial push on the yoke, involve eliminating unnecessary drag. Think of any
improvements you make in that department as regaining some of the thrust you
just lost in the engine failure. I hope flight
instructors reading this will take a cue from
multiengine training and incorporate more
of these engine-out scenarios, along with
being spring loaded to push on the yoke and
minimize drag, into training.

Terms and Conditions for full details at AOPA.org/creditcard.
1. Rewards points can be redeemed for Cash Back or other items provided through AOPA Pilot Rewards. A Cash Back redemption is applied
as a statement credit. The statement credit will reduce your balance
but you are still required to make at least your minimum payment. A
minimum of 2,500 points is needed to redeem for Cash Back. Values for
non-cash back redemption items such as merchandise, gift cards, and
travel may vary. 2. Advertising, Aviation Insurance, PAC Donations and
AFI Donations are excluded. Visit www.commercebank.com/aopapilotrewards for complete details on exclusions and bonus point categories. 3.Participating AOPA partners include: Aero-Space Reports, Aircraft Spruce & Specialty Co., Jeppesen®, Pilot Workshops, SiriusXM®,
Sporty's® Pilot Shop. The listed AOPA partners are in no way affiliated
with Commerce Bank, nor are the listed merchants to be considered
sponsors or co-sponsors of this program. Use of merchant names and/
or logos is by the permission of each respective merchant and all trademarks are the property of their respective owners 4. Please note that
merchants self-select the category in which transactions will be listed
and some merchants may be owned by other companies, therefore
transactions may not be counted in the category you might expect. Purchases made using Near Field Communication (NFC), virtual wallets, or
similar technology may not be eligible for bonus points. 5. You will earn
4% Cash Back (1 regular point + 3 bonus points = 4%) for every $1 of
Net Merchandise Purchases on select AOPA purchases, 3% Cash Back
(1 regular point + 2 bonus points = 3%) for every $1 of Net Merchandise
Purchases made at select AOPA partners, 2% Cash Back (1 regular
point + 1 bonus points = 2%) for every $1 of Net Merchandise Purchases made at FBOs (fixed based operators), aviation and auto fuel, and
flight schools, and 1% Cash Back (or 1 point) for every $1 of other Net
Merchandise Purchases. For example, if you spend $100, you will earn
100 points which is equal to $1 in Cash Back rewards. A maximum of
2,500 bonus points will be awarded per calendar quarter, per rewards
account. Please allow up to five business days after the transaction
posts to your account for bonus points to be awarded.
