Training Tips

The why of winglets

Training TipA light sport aircraft taxies by as you are tying down your trainer after the day’s flight lesson.

 

“Notice anything unusual about that airplane?” asks your instructor.

 

Given the question, you know the answer has to be “yes,” so you give the aircraft an extra careful inspection as it rolls past.

 

Winglets,” the CFI says, pointing to small vertical airfoils at the tips of the airplane’s wings.

 

Why winglets?

 

Frequently a design element of large jet and turboprop aircraft, winglets—designed to address aerodynamic inefficiencies of the airflow around wingtips—have begun to appear as original equipment or as aftermarket installations on smaller aircraft. The basic idea is that winglets can counteract a loss of lift resulting from the phenomenon of wingtip vortices.

 

“The high-pressure area on the bottom of an airfoil pushes around the tip to the low-pressure area on the top,” explains the Pilot’s Handbook of Aeronautical Knowledge. “This action creates a rotating flow called a tip vortex. The vortex flows behind the airfoil creating a downwash that extends back to the trailing edge of the airfoil. This downwash results in an overall reduction in lift for the affected portion of the airfoil. Manufacturers have developed different methods to counteract this action. Winglets can be added to the tip of an airfoil to reduce this flow. The winglets act as a dam preventing the vortex from forming. Winglets can be on the top or bottom of the airfoil.”

 

Designs have advantages and drawbacks, so designers are further subdividing winglets as either passive or active devices.

 

“Passive winglets such as those found on airliners and business jets today impart a bending moment to the wing, due to the extra lift they provide at the very tip,” explained this October 2012 AOPA Online article. “Either the wing connection to the fuselage must be strengthened, or the winglets must be small enough to avoid extra strain.” By contrast, active winglets tested by AOPA are designed to “turn off” the extra lift when wing loads are high.

 

More benefits were suggested when recent testing of winglets on a Piper Aerostar twin-engine aircraft demonstrated better handling during stalls, and increased safety margins in slow-speed flight.

 

Winglets are even finding their way into future propeller design for the light sport and experimental aircraft market, striving for the dual benefits of increased efficiency and reduced noise.

Airplanes, potato chips: It just takes a taste, school says

Take a couple of shiny, new aerobatic aircraft and match them with enthusiastic, expert instructors, and you might just have a winning combination when it comes to spreading the passion for aviation and recruiting new pilots. California’s 5g Aviation is banking on that, and so far, it seems to be succeeding. “If you get in that airplane and go up with one of my instructors, you’re going to fly again,” said 5g Aviation CEO Ty Frisby. “It’s like you can’t just eat one potato chip.” Read more >>

FAA agrees to drop dated material from knowledge tests

The FAA has agreed to remove questions that focus on obsolete terms and technologies from airman knowledge tests in response to a request from the co-chairs of an industry/government group that is drafting revisions to training and testing standards. AOPA welcomed the FAA’s response as a “very positive step” to advance the goals of the Aviation Rulemaking Advisory Committee’s Airman Testing Standards and Training Working Group. Read more >>

NASA holds aerospace education program for teens

After spending six months learning and communicating via the Web, 170 rising high school seniors from across Virginia are working on an intensive aerospace education program by planning a mission to Mars during weeklong summer academies at NASA Langley Research Center. Students are part of the Virginia Aerospace Science and Technology Scholars (VASTS) program, an interactive, online science, technology, engineering, and mathematics (STEM) learning experience that offers student participants workforce experience as well as college credit.

Independence Aviation, STEM Ventures team for summer youth lab

Twenty sixth- through ninth-grade students from Colorado's South Metro Denver area will get up-close-and-personal with the world of flight in July at Centennial Airport through a weeklong learning lab held jointly by Independence Aviation LLC, a flight school/flight services company based at the airport, and STEM Ventures LLC, which provides science, technology, engineering, and mathematics (STEM) education for K through 12 students. Highlights of the week include a tour of an aviation maintenance facility, a tour of the Metropolitan State University of Denver Aerospace Department, and taking the controls of simulated flights in Independence Aviation’s Frasca Cirrus SR22 Level 1 flight training device.

Do you know where you are? Are you sure?

Knowing where you are on the airport seems like a simple task, but its importance cannot be overstated. Confusing airport layouts, poorly lit (or completely unlit) runways or taxiways, and in-cockpit distractions are all factors pilots must be aware of, or disregard at their own peril. In this animated video from the Air Safety Institute, watch as a lack of situational awareness ends with a fatal outcome. Watch the video >>

You and your aircraft

As you learn to fly, your skills are improving, and you are becoming a better pilot. But is your airplane improving along with you? After all, each one of those bounced landings and abrupt power changes takes its toll on the aircraft's service life. Learn more about the wear and tear an aircraft endures, the telltale signs of aircraft fatigue, and much more by taking the Air Safety Institute's Aging Aircraft online course.

Court upholds Delta, ALPA challenge to loan guarantees

The Washington, D.C., Circuit Court of Appeals on June 18 upheld a challenge by Delta Air Lines and the Air Line Pilots Association to Export-Import Bank loan guarantees for 30 long-range, widebody aircraft sold to Air India. “Delta and ALPA had argued that the subsidies would have harmful effects on U.S. airlines and their employees,” Delta said. “The federal appeals court held that, before issuing its loan guarantees to Air India, the bank was required by its governing statute to consider the effects that the loan guarantees would have on U.S. industries and U.S. jobs.” The bank failed to explain its exclusion of aircraft transactions from economic impact review, according to the court.

Final Exam

 

Question: What regulation dictates the passenger briefing on airline flights?

 

Answer: Airlines that run scheduled passenger service operate under Part 121 of the federal aviation regulations. The regulation that specifically outlines what needs to be in this pre-takeoff passenger briefing done by flight attendants is in FAR 121.571. It requires the airline crew to brief passengers on smoking, emergency exit locations, location and use of floatation devices, seat back positions for takeoff and landing, location of survival equipment, and use of oxygen. This explains why airlines have different briefings, but they must contain these same highlighted topics in the briefing.

Instrument Tip

IFR Fix: Between SATAN and SCUPP

An instrument pilot was planning a flight to Logan International Airport in Boston, Mass., from an airport about 150 miles to the northeast. He thought he knew what routing to expect from hearing radio readbacks, but he hadn’t actually spread charts and noticed where a clearance to SCUPP would take him. Doing so brought a surprise—and a decision not to accept any routing that would take him farther east than WIMPY. Read more >>
