Convective sigmets

The weather looked great when you launched on today’s solo cross country. There was a cold front headed into the area, your weather briefer said, but frontal passage and any associated weather activity was not expected until tomorrow. But as the day wore on, those typical fair-weather cumulus clouds seemed to take on a more ominous appearance, growing higher and darker. Acting on your gut feeling that weather changes might be afoot, you dialed in a HIWAS frequency or contacted Flight Service by radio for an update. HIWAS was discussed in the Aug. 22, 2003, “Training Tip: Keeping Tabs on the Weather.


Two words that you heard over the radio got your immediate attention: Convective sigmet 45E has been issued near your route “for a line of severe thunderstorms 15 nautical miles wide, moving from 250 degrees at 15 knots, tops above Flight Level 450. Hail to one inch, gusts to 50 knots possible.” Hail greater than three-quarters of an inch in diameter is always included in a convective sigmet or an urgent pilot report; see the July 17, 2009, Training Tip.


What exactly is a sigmet? It is a National Weather Service contraction that stands for significant meteorological information. A sigmet is an in-flight weather advisory “considered significant to all aircraft,” as explained in Chapter 11 of the Pilot’s Handbook of Aeronautical Knowledge . When such an advisory is concerned with convective weather, the sigmet is named accordingly.


Updating your weather information from the air is not the only way you may learn that a sigmet is in effect. Aviation weather forecasts refer to these weather advisories as well. The AOPA Air Safety Foundation publication Weather Strategies contains a transcript of a telephone weather briefing in which the briefer reviews a convective sigmet such as the one described above with a pilot.


Take some time to familiarize yourself with the information a sigmet contains. Then try your hand at the two questions about sigmets in the August 2008 AOPA Flight Training ’s Final Exam.


Convective or not, the issuance of a sigmet is need-to-know information for any pilot. So stay informed about weather, and be ready with a plan of quick action.


Every pilot needs to remain vigilant during ground operations. To help ensure that you know where you are in reference to taxiways and runways, always use an airport diagram and mark the runway in use with the heading bug on your heading indicator. Once you're on the runway, verify that the heading indicator (and bug) are aligned with the runway. Pilots should also know the meaning of all airport signs and markings. To help you brush up on signs and markings, review the AOPA Air Safety Foundation's Runway Safety online course and Runway Flash Cards. Free airport diagrams are also available on the foundation's Web site.


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.

Lindbergh Foundation extends grant deadline

The Lindbergh Foundation has extended the deadline for aviation-related grant applications until Oct. 30. The foundation’s grant program seeks entries of aviation/aerospace research projects that balance technological advancements with the preservation of the environment. The $10,580 research grants are given to individuals; projects need not be associated with a university, business, or nonprofit organization. For more information, see the Web site or call 763/576-1596.

Stay oriented with new animated quiz

In July 1999, John F. Kennedy Jr. succumbed to spatial disorientation in the evening haze off Cape Cod, sending his Piper Saratoga into a tight, high-speed spiral that ended in tragedy. In the decade that's followed, nearly 300 other pilots—some of them instrument rated—have similarly lost their bearings in the soup, and many lost their lives. Challenge your knowledge of spatial disorientation with the latest interactive safety quiz from the AOPA Air Safety Foundation, which uses flight simulator animation to illustrate how quickly an accident can develop—and how you can avoid a similar fate.

ERAU has busy AirVenture schedule

Embry-Riddle Aeronautical University will have a big presence at EAA AirVenture 2009 in Oshkosh, Wis. The university is sponsoring aerobatic pilot Matt Chapman, who will fly a CAP 580 called the Embry-Riddle Eagle. On display will be two training aircraft, a Diamond DA42 and Cessna 172, both equipped with Garmin G1000 glass cockpit displays. Aviation entrepreneur and airshow performer Jamail Larkins will speak July 31 during a “Lunch with Embry-Riddle” for middle- and high-school students. Also, the university will have on display its jet-powered dragster, and participants can meet its driver, Elaine Larsen.

Jacksonville University gets training software

Jacksonville University’s Division of Aeronautics recently received a donated regional jet software training program. Donor CPat of Houston, Texas, said the ERJ 145 aircraft systems training program is a comprehensive, self-paced learning tool that will maximize the amount of learning achieved and save students money.

Chinese delegation visits AOPA

Eleven delegates from the Civil Aviation Administration of China (CAAC), their interpreter, and other guests visited AOPA headquarters in Frederick, Md., on July 16 as part of a 12-day trip to research general aviation in the United States. A high point for the group, charged with developing general aviation in China, came when the delegates got to fly in GA airplanes, including the 2009 Let’s Go Flying Sweepstakes Cirrus. For many, it was their first opportunity to do so. Read more >>

Question: I am planning a flight into a small, nontowered field. Looking in the Airport/Facility Directory, I noticed that there is both a unicom frequency and a CTAF. Can you tell me what the difference between these two frequencies is and which one I should use to announce my position?


Answer: CTAF is the common traffic advisory frequency. This is the primary and preferred frequency for providing position reports while flying at or near an airport. The unicom frequency is shortened from "universal communications." This is the frequency you would use to communicate with the FBO or airport itself. You can use the unicom frequency to inquire about the preferred runway, wind direction, and other pertinent information. For more information on radio communications, check out the AOPA Air Safety foundation’s newest interactive course, Say It Right: Mastering Radio Communication.
