As your aircraft moves through the air, the angle of attack—that is, the angle between the chord line of its wing and the relative wind—produces lift and drag that the pilot harnesses to achieve the desired flight profile. Student pilots learn that exceeding the critical angle of attack produces an aerodynamic stall; practicing stall recognition, entries, and recoveries is a basic component of primary flight training.
What controllability characteristics does your trainer exhibit as it approaches the critical angle of attack, and during stall recovery? What you experience during practice is the result of how another angle—this one a fixed design feature of your aircraft’s wing—works to affect flight characteristics.
This design feature is the wing’s angle of incidence, defined as “the angle formed by the chord line of the wing and a line parallel to the longitudinal axis of the airplane.”
A desirable feature of a wing is for it to stall at the root before the wingtip. Why is that a plus?
This excerpt from an AOPA review of the Piper PA-28-161 Warrior explains, noting how the Warrior’s wing employs “washout” of the wing’s angle of incidence to achieve the desired stall characteristic: “Stand at the wingtip and sight down the leading edge, and you’ll notice that the leading edge twists slightly downward near the tip. This decrease in the angle of incidence means that even when the wing root area has stalled, the outer portion of the wing continues to generate lift and the ailerons remain effective. All of that means the airplane is more controllable in an aerodynamic stall.”
Other aircraft get the same result through different means. AOPA reported that the composite Cirrus SR20's wing incorporates a cuff on the leading edge to influence airflow: “The cuff causes the air flowing over the ailerons to remain ‘attached’ to the wing at very high angles of attack. As a result, the ailerons remain effective even after the inboard portions of the wing have stalled.”
Flight Training News
Shivering and panting in the waters just off the Southern California coast, AOPA Editor—Web Sarah Brown gripped the white straps of the life raft ladder, found the lowest rung with her foot, and paused. Her heart was still racing from hitting the 65-degree water—warm by ocean standards, but cool enough to trigger the gasping reflex and rapid heartbeat of cold shock response—and she knew she must stay calm. Brown pulled hard, leaned forward, and splashed head first onto the floor of the raft. Read more >>

Learn more and register online.
Is it really as simple as ‘push this, go faster?’
As pilots, we spend a lot of time learning about aerodynamics and manipulating the forces of flight, but we don’t spend much time studying what gets us aloft in the first place: our propulsion system. In the Air Safety Institute’s Engine and Propeller online course, you’ll dig deep under the cowling and learn how what you do with the throttle and prop control really translates into what’s going on beyond the firewall.

United becomes 787-10 North American launch customer
United Airlines increased its 787 Dreamliner order to 65 aircraft, including six previously delivered aircraft, June 18 with an order for 20 787-10s. United is the North American launch customer for the 787-10 and it expects delivery of its first aircraft in 2018. United ordered 10 incremental 787-10 aircraft and will convert 10 existing 787s on order to 787-10s, enabling the airline to further modernize its international widebody fleet by replacing older, less efficient aircraft. United had previous orders for an additional 49 Dreamliners consisting of both the -8 and -9 variants; the 787-10 is a stretched version of the 787-9.
Horizon to add more Q400 turboprops
Bombardier Aerospace announced June 18 that Seattle-based Horizon Air has signed a firm contract to acquire three 76-seat Bombardier Q400 NextGen turboprop airliners, converting previously booked options on the aircraft. The airline also reconfirmed its options on another seven Q400 NextGen aircraft. Based on the list price of the Q400 NextGen aircraft, the contract is valued at approximately $98 million. The three new aircraft increase Horizon Air's orders for Q400 and Q400 NextGen airliners to 51 aircraft. "The addition of these three Q400 NextGen aircraft will allow us to venture into the state of Alaska, which is considered America's last frontier, and is now an exciting new frontier for Horizon," said Glenn Johnson, Horizon Air president.

What twin turboprop has centerline-mounted engines, a business-jet-quality cabin, and an oar and an anchor as standard equipment? That last bit about nautical gear should clinch it, but even veteran plane spotters may be in over their heads unless they can identify the Dornier Seastar. Far from frequently found afloat or in flight, a prototype of the PT-6-powered aircraft was prominently previewed at recent major aviation conventions. Dornier calls the Seastar “the most advanced amphibious seaplane in the world.” As of a 2010 AOPA Live® interview, the price was $6 million.
