5. Which is true concerning the blue and magenta colors used to depict airports on sectional aeronautical charts?

B. Airports with control towers within Class B, C, D, and E airspace are shown in blue.
C. Airports with control towers within Class C, D, and E airspace are shown in magenta.
6. Airspace at an airport with a part-time control tower is classified as Class D airspace only
A. when the associated control tower is in operation.
B. when the associated Flight Service Station is in operation.
C. when the weather minimums are below basic VFR.
7. A 100-hour inspection was due at 3302.5 hours. The 100-hour inspection was actually done at 3309.5 hours. When is the next 100-hour inspection due?
A. 3312.5 hours.
B. 3402.5 hours.
C. 3409.5 hours.
8. Should it become necessary to hand-prop an airplane engine, it is extremely important that a competent pilot
A. be in the cockpit and call out all commands.
B. be at the controls in the cockpit.
C. call “contact”’ before touching the propeller.
1. The correct answer is A. Sufficient water vapor, an initial lifting force, and an unstable lapse rate are the three main ingredients necessary for the formation of thunderstorms. While these three combined will not always produce a thunderstorm, no thunderstorm will form without them. (Pilot’s Handbook of Aeronautical Knowledge, Chapter 11)
2. The correct answer is A. The cumulus stage can be described as the building stage of a thunderstorm, identified by building and towering cumulus clouds created by continuous updrafts. Lightning, thunder, and rain are most prevalent in the mature stage, while the dissipating stage is characterized primarily by downdrafts as the storm fizzles out. (Pilot’s Handbook of Aeronautical Knowledge, Chapter 11)
3. The correct answer is B. You might recall that the notam-L service was discontinued several years ago. Distant notams (notam [D]) that are expected to remain in effect for an extended period, and flight data center (FDC) notams, are published in the Notices to Airmen publication. (Aeronautical Information Manual, Section 5-1-3)
4. The correct answer is C. Excessively high engine temperatures that exceed the redline markings on CHT, EGT, or oil temperature gauges can lead to power loss, internal engine damage, and high oil consumption. Reducing power, reducing rate of climb, increasing airspeed, descending, enriching the mixture, opening cowl flaps, and/or flight termination all are possible cures. (Pilot’s Handbook of Aeronautical Knowledge, Chapter 6)
5. The correct answer is B. Airports with control towers are depicted with a blue airport symbol on sectional aeronautical charts. Control towers are usually within class B, C, D, and E airspace. (Aeronautical Chart Users Guide)
6. The correct answer is A. Many ATC towers are part-time operations, closing usually late at night through early morning. When closed, the airspace would revert to a lower class—either E or G. (Airport/Facility Directory)
7. The correct answer is B. As the FAA is not in the business of handing out free passes, for any 100-hour inspection time that is exceeded, that time must be subtracted, hour for hour, to determine the time the next one is due. (FAR 91.409[b])
8. The correct answer is B. If it is necessary to hand-prop an engine installed in an airplane that has a battery and electric starter, the airplane may be unairworthy before the flight even begins. However, if you are flying a Piper J–3 Cub, the “armstrong” starter is standard equipment, and this technique is actually required prior to any flight. Most important, ensure the controls are handled by a pilot familiar with that airplane. (Airplane Flying Handbook, Chapter 2)
