Positioning the ‘CG’
You performed a weight-and-balance calculation for your trainer’s next flight, pleased that weight was below max and the center of gravity (CG) within limits. Good work—but don’t consider the matter closed yet. Did you think about the loading arrangement you chose in terms of the aircraft handling to expect? That’s especially important if you’ll be practicing maneuvers involving flight at high angles of attack (slow flight, stalls) or high load factors (steep turns).
Heading out with an unusually aft CG could produce aircraft behavior that you have never seen from the trainer whose predictable handling you have come to trust. What could yield an unusually aft CG position? A rear-seat observer, extra weight in the baggage compartment, or a lower-than-usual fuel supply, to name a few possibilities.
"Because the CG’s location determines in part how an aircraft flies, manufacturers set forward and aft CG limits that ensure safe, predictable flying qualities. It’s every pilot’s responsibility to ensure the CG falls within these limits. Ignoring this responsibility can be disastrous. Even when the CG is within limits, handling characteristics can vary depending on the location of the CG," Ed Kolano explains in the April 1997 AOPA Flight Training " Form and Function: Center of gravity."
Handling differences may not become apparent until maneuvering practice commences. "Some pilots are genuinely startled when performing stalls in an adversely loaded airplane. A few have confessed that they were shocked at how unexpectedly their airplanes behaved," Barry Schiff writes in the January 2007 AOPA Pilot column " Proficient Pilot: CG at the aft limit."
So, what happened? "The recovery from a stall in any aircraft becomes progressively more difficult as its CG moves aft. This is particularly important in spin recovery, as there is a point in rearward loading of any aircraft at which a ‘flat’ spin develops," according to Chapter 4 of the Pilot’s Handbook of Aeronautical Knowledge .
Convinced? Then be sure to positively position your CG appropriately before flight. Don’t just check the chart and take what you get. Then tackle the questions on weight and balance, and aircraft stability, on the Private Pilot Knowledge Test with new appreciation for this critical aerodynamic topic.
YOUR PARTNER IN TRAINING
The most common error by pilots that leads to runway incursions is entering a runway without clearance, meaning the pilot moves into a takeoff position prematurely or crosses a runway without clearance. To help you better understand runway signage, the AOPA Air Safety Foundation offers a free online Runway Safety Program . Using active motion and 3-D graphics, the Runway Safety Program takes pilots through real-life situations involving operations with high potential for runway incursions.
Did you know that student pilots who join AOPA are three times more likely to complete their flight training? Membership includes unlimited access to aviation information by phone (800/USA-AOPA, weekdays from 8:30 a.m. to 6 p.m. Eastern time) or from AOPA Flight Training Online or AOPA Online.

In an effort to reach out to students on the University of Illinois campus and perhaps bolster enrollment in the aviation program, the school’s Institute of Aviation will host a Fun Flights program in October. Participants will experience a one-hour aerial tour of the campus and surrounding area in one of the program’s 18 Piper Archers. The aviation program has lost 30 students since last year, out of a total of 230 students. The enrollment drop has been attributed to the economy and a decline in financial aid for students, according to the Daily Illini .
The depressed economy has caused a Lincoln, Calif., fixed-base operator to discontinue the flight training portion of its business. Ken Atkin, owner of Atkin Air at Lincoln Regional Airport, said the business was hit especially hard because clients who had paid for charters and flight training "aren’t anymore. The money they use for that, it’s recreational. They’re going to pay their house payments before they go flying," he told the Lincoln News Messenger . Charter and aircraft management services will still be available.
ERAU student wins trade group scholarship
The Florida Aviation Trades Association has awarded a scholarship to Embry-Riddle Aeronautical University senior Wayne Williams. Williams, of Atlanta, Ga., is a senior at the Daytona Beach, Fla., campus. He is a single- and multiengine commercial pilot with instrument ratings and is working on a flight instructor certificate.
Brothers bring flying business to Texas hometown
Two brothers who own and operate a fixed-base operation in Texas recently moved the business to their hometown of Athens, Texas, and have added flight training to the mix. Wayne and Gaylon Adkisson own Athens Jet Center, which they moved to Athens Municipal Airport earlier this year. A new hangar is planned, and the business is working on an agreement with Trinity Valley Community College to offer flight and ground school classes, according to the Athens Daily Review .
The questions that run through your head while you’re talking to air traffic control can be critical to the safety of your flight: How do controllers handle my situation differently if I declare "minimum fuel" versus a "fuel emergency"? Or, the questions may simply be driven by curiosity: How can I get a tour of an ATC facility? Get the answers in the AOPA Air Safety Foundation Ask ATC resource. Learn from others’ questions and ask your own to find out everything from how controllers handle a stuck microphone to what happens if you bust an altitude. Answers come straight from the National Air Traffic Controllers Association.
The tips and practical techniques you learn from an AOPA Air Safety Foundation Safety Seminar just might save your life, said one pilot who attended a "Takeoffs and Landings" seminar. The pilot said the safety preparation techniques she learned helped her instantly and successfully respond to an engine failure, safely making the runway. All of the seminars qualify for the FAA Wings program and AOPA Accident Forgiveness and Deductible Waiver Enhancements. More than 40,000 pilots a year attend the foundation’s free seminars. Find out when the latest seminar, " What Went Wrong?," will be in your area.

Question: I am interested in performing an owner-assisted annual to help save some money and learn more about my aircraft. Does AOPA have any resources to assist me in this process?
Answer: An owner-assisted annual is a great way to save a little money and learn more about your aircraft. While only an airframe and powerplant mechanic with inspection authorization (IA) privileges may perform the inspection, the owner can help with maintenance functions and provide general assistance. To learn more about the owner-assisted annual inspection, watch this AOPA Air Safety Foundation Safetycast. You can also review this article from AOPA Flight Training magazine.
