A student pilot and a flight instructor are reviewing after a session of flight-test prep for the student’s private pilot checkride. The focus is on the slow flight and stall maneuvers to be demonstrated on the flight test, and the honing of the student’s understanding of the all-important angle-of-attack concept.
In a mock oral exam, the CFI asks, “What is a key difference between the straight-ahead power-on stalls we performed today and the power-on stalls we performed in turning flight?”
The checkride applicant replies, “Maintaining the bank angle of 20 degrees was a challenge during the turning stall entries. The necessary control pressures kept changing. Not just bank, but the pitch and rudder inputs, too!”
What was going on?
Find the explanation in Chapter 4 of the Airplane Flying Handbook; it’s cited as a reference for the maneuver in the Private Pilot Practical Test Standards.
During the approach to a power-on turning stall, the pilot must control both an overbanking tendency and a tendency toward lower pitch while maintaining “the pitch attitude that will induce a stall,” as required for the PTS task.
With the aircraft established in a nose-high turning attitude, “the angle of bank has a tendency to increase,” explains the chapter. “This occurs because with the airspeed decreasing, the airplane begins flying in a smaller and smaller arc. Since the outer wing is moving in a larger radius and traveling faster than the inner wing, it has more lift and causes an overbanking tendency.”
As for pitch: “At the same time, because of the decreasing airspeed and lift on both wings, the pitch attitude tends to lower.”
The busy pilot must control another effect as well: “In addition, since the airspeed is decreasing while the power setting remains constant, the effect of torque becomes more prominent, causing the airplane to yaw.”
All that explains why constantly changing control pressures are needed to perform a maneuver that uses a single, specified bank angle “not to exceed 20 degrees, ±10 degrees.”
And here’s a follow-up tip for a smooth turning stall entry and recovery: When the stall occurs, remember during your recovery to ease off on those aggressive control pressures; they won’t be needed for control when induced drag decreases with the lower angle of attack, and flight control responsiveness returns!
Flight Training News
Howell, Mich.-based Crosswinds Aviation is hoping that a program it's doing with Howell High School and the local EAA Young Eagles chapter will help get more youths interested in general aviation.

Two weeks to triumph
Eight teenagers got down to business during a two-week odyssey helping to build two Glasair kit airplanes. The teens, who attend high schools in Michigan and Minnesota, arrived in Arlington, Wash., on June 16 after winning an aircraft design competition sponsored by Build A Plane and the General Aviation Manufacturers Association. They spent two weeks at the Glasair factory in Arlington, working alongside mentors and company representatives who shepherded them through Glasair’s Two Weeks to Taxi program. Read more >>

Tuskegee Airmen help Atlanta minority student pilot training program
A new aviation training program targeting minority students in Atlanta is getting a helping hand from some of the original Tuskegee Airmen, reports WSB-TV. The aviation legends, in partnership with their local chapter and Delta Air Lines, are working with 30 students to give them hands-on training and expose them to different aviation careers.

Company proposes travel/flight training program
The principals of San Francisco-based Visionary Airlines hope they can get funds via an Indiegogo fundraising campaign to create the Flight Training Adventure, which will allow students to travel within California while logging time toward a private pilot certificate. Those who contribute can earn special perks, including flights around San Francisco Bay or to Yosemite National Park.
Leaving the nest
As pilots, the world is our backyard, and long-distance travels can be completed with relative ease. But we also live in a world with borders. Thus, there is the potential for long waits for general aviation pilots to receive clearance from U.S. Customs and Border Protection. The electronic Advance Passenger Information System, or eAPIS, is available to speed your way through the process. It is not only a good idea—it is the law. Learn more about this system, and how to use it when you travel abroad, by taking the Air Safety Institute’s Understanding eAPIS: A Pilot’s Guide to Customs Reporting online course.

Florida Tech and Copa Airlines join for flight training
The Florida Institute of Technology College of Aeronautics is now associated with the Latin American Academy for Superior Aviation, a nonprofit institution sponsored by Panama flag carrier Copa Airlines. Under the deal, Florida Tech will provide pilot training and management oversight for the new school through its flight training arm, FIT Aviation. Training, already begun with an initial 40 students from Panama and elsewhere in Latin America, supports Florida Tech’s ongoing program in Panama to offer aviation degrees.
FedEx shedding thirsty jets
With the economy not growing as quickly as forecast, FedEx Corp.—which is undergoing a $1.7 billion restructuring—will accelerate plans to retire 86 older, inefficient aircraft, Bloomberg reported June 4. The carrier is retiring five Airbus A310s and five McDonnell Douglas MD-10s immediately, and will accelerate the scheduled retirements of 60 MD-10s and 16 A310s. FedEx has ordered 70 new Boeing 777 and 767 jets, and said in March it would buy 14 used 757s from United Continental Holdings—a number that could increase.

Plane spotting is best practiced on terra firma. Still, plane spotters’ knowledge goes where they go—and nothing will grab the attention of two spotters flying the traffic pattern in a Cessna 172 like the tower saying, “Make short approach. Your traffic is a Galaxy on a two-mile final.” Landing and (promptly) taxiing clear, the plane spotters check how closely the huge C-5 was trailing, only to see a mid-sized business jet touching down. Did somebody cut in? No. This is a Gulfstream G200, named after its original manufacturer, Galaxy Aerospace.

Are you really good to go if it doesn’t say so?
The “it” in the title refers to aircraft maintenance records. FAR 91.403(a) says the owner or operator of an aircraft is primarily responsible for maintaining that aircraft in an airworthy condition. FAR 91.405(b) essentially says that the owner or operator shall ensure that maintenance personnel make appropriate entries in the aircraft maintenance records indicating the aircraft has been approved for return to service following the performance of required maintenance.

Obtaining quotes to insure your aircraft
A little trick of the trade is that when requesting quotes, you should never rely solely on the application to present your information. A follow-up phone call with the insurance broker is the best method for getting the best coverage, particularly if you’re a new pilot, insuring a new type of airplane, or planning on flying to new places.
