Training Tips

Charting the carb ice risk

Training TipThere’s nothing like a summer heat wave to take your mind off all things cold and icy. In aviation, however, that’s not entirely warranted, as some pilots discover when experiencing a sudden engine-choking encounter with carburetor ice on a hot and humid day.

 

Then, if a pilot doesn’t respond correctly by applying carburetor heat as the aircraft’s operating checklist recommends, the encounter can progress to a complete engine failure—and an off-airport landing.

 

Student pilots learn that under the right conditions, moist air passing through a float-type carburetor throat can chill below the freezing point, depositing ice that chokes off the flow of the fuel-air mixture. Student pilots also learn that generally, a high-risk temperature range is between 50 and 70 degrees Fahrenheit.

 

Accidents indicate that some pilots fail to recognize conditions conducive to carb ice formation, and its symptoms. But there’s no reason to be caught completely off-guard about the risk.

 

When accident investigators review conditions encountered by an aircraft that lost power in flight, one of the tools they use in determining an accident cause is a carburetor icing probability chart. Note how this valuable graphic illustrates that an increase in the air’s relative humidity elevates the carb-icing risk in two flight phases: cruise power and glide power. Note also how risk rises at higher ambient temperatures in both phases.

 

Just as important as knowing when carb ice is likely to form is the ability to recognize symptoms of icing’s onset.

 

“It is imperative for a pilot to recognize carburetor ice when it forms during flight because a loss of power, altitude, and/or airspeed will occur,” explains Chapter 6 of the Pilot’s Handbook of Aeronautical Knowledge. “These symptoms may sometimes be accompanied by vibration or engine roughness. Once a power loss is noticed, immediate action should be taken to eliminate ice already formed in the carburetor, and to prevent further ice formation. This is accomplished by applying full carburetor heat, which will cause a further reduction in power, and possibly engine roughness as melted ice goes through the engine.”

 

Applying carburetor heat can reduce power by as much as 15 percent. Strong evidence that ice was present is a gradual increase in power to an rpm or manifold-pressure value higher than just before heat was applied.

 

Start with the chart and avoid the carb ice hazard!

Air Safety Institute materials used for Afghanistan ground school

Materials published by the Air Safety Institute are helping pilots in Afghanistan keep their skills sharp in the combat zone. Even though soldiers are in Afghanistan, the Department of Army Standardization still requires them to keep up their aviation skills. That is how ground school training materials from the AOPA Foundation’s Air Safety Institute ended up with Alpha Company 2/104th GSAB 2-104th General Support Aviation Battalion’s Task Force Phoenix at Bagram Airfield.

Sikorsky launches Helicopter 2050 Challenge

Sikorsky Aircraft has launched the 2013 Sikorsky Helicopter 2050 Challenge, a national competition that invites youths aged 9 through 16 to design a helicopter capable of addressing global issues likely to be encountered by mid-century. The winner of the grand prize—the Igor Sikorsky Youth Innovator Award—will receive a $1,000 scholarship, meet with Sikorsky rotorcraft engineers, and receive an expenses-paid tour of the Black Hawk and Seahawk helicopter assembly lines at the company’s Stratford, Conn., headquarters.

University uses Asiana accident for safety training

The University of Dubuque’s aviation program, with about 170 flight students, is using the recent Asiana Airlines accident as a learning tool in the classroom, reports KWWL-TV. The school is using a CRJ200 flight simulator to help students get the flight hours they need before becoming airline pilots.

UND Foundation makes donation to LA aircraft mechanics school

The University of North Dakota (UND) Aerospace Foundation has donated $25,000 to the Los Angeles Unified School District’s struggling aircraft mechanics school. The money will provide scholarships to low-income students preparing for jobs as airframe and powerplant mechanics. The school was under a threat of closure due to budget cuts.

Training Resources

Ramp operations

Knowing what will keep you and your passengers safe is the key to conducting each flight safely. Because the ramp area can be full of hazards, educating yourself about some of the common dangers on the ramp will help you navigate to and from your aircraft without incident. This safety brief examines some of the things you can do to protect yourself, and your passengers, each and every time you go flying. Download the PDF >>

AOPA LIVE

Medical petition update, DHS leadership vacuum

AOPA President Craig Fuller wonders why a straightforward request that would save pilots and the government millions of dollars has taken more than a year (and counting) to draw any FAA response: The joint AOPA/Experimental Aircraft Association petition to allow pilots to fly many common four-seat aircraft with a driver’s license in lieu of a third class medical remains in limbo, and Fuller checks in with the latest. AOPA Live This Week also looks at how a leadership vacuum at the U.S. Department of Homeland Security is complicating efforts to correct a heavy-handed approach by federal agents searching GA aircraft; Rod Machado offers tips on how to eyeball a glidepath; and AOPA Live® will take you for a ride in a Diamond twin that just sips fuel. As of publication time, AOPA Live producers were finalizing this week's episode. Check back on the AOPA Live page for the latest edition that will be available July 19.

Career Pilot

Delta to add 225 flight attendants

Delta Air Lines will hire 225 flight attendants later in 2013 and intends to hire even more during 2014. The airline is hiring cabin crew as it prepares to integrate 88 Boeing 717s, being phased out by Southwest Airlines subsidiary AirTran Airways, into its fleet, the Atlanta Journal-Constitution reported July 5. Delta will receive the first AirTran jets in September and will place them into service over the next few years, replacing 50-seat regional jets. Delta is not accepting applications, however. According to the newspaper report, new flight attendants will come from an existing pool of applicants.

Plane Spotter

Flight of the ‘fenestron’: Eurocopter EC135

Eurocopter EC135Some aircraft are just obviously visually distinctive, a characteristic that puts them right in the wheelhouse of plane spotters looking to expand their aircraft-identification repertoires. And speaking of wheel housings, sometimes plane spotters examining an intriguingly novel airframe also find themselves expanding their vocabularies of aerodynamic terms. A striking structural feature of the Eurocopter EC135 helicopter is its shrouded tail rotor. Known as a fenestron, the design—evident to any plane spotter—is a feature of many Eurocopter light models, and the company considers it “a trademark of the brand.”

Final Exam

 

Question: I’m looking at a METAR and I see the letters “CB.” What does this stand for?

 

Answer: CB stands for cumulonimbus clouds. CBs always evolve from the further development of towering cumulus clouds (TCU). The unusual occurrence of lightning and thunder within or from a CB leads to its popular title, a thunderstorm. Thunderstorms usually contain severe or greater turbulence, severe icing, low level wind shear (LLWS), and instrument meteorological conditions (IMC). You can expect thunderstorm conditions anytime you see the letters CB in a METAR. A great resource to consider picking up is the FAA’s Aviation Weather Services publication, Advisory Circular 00-45.
