TEST PILOT ANSWERS from page 40 1. True. The submarine was sunk by a depth charge dropped from a Grumman Widgeon. Smaller aircraft carried 100-pound bombs. CAP pilots spotted 173 subs, attacked 57, and damaged 17. These pilots also helped to save 363 survivors of sub attacks, summoned help for 91 vessels in distress, and found 17 floating mines. During World War II, 59 CAP crewmembers were killed. 2. The Lockheed C-130 Hercules. 3. True. A switch on the throttle allowed the pilot to adjust propeller pitch between 22.5 and 90 degrees. (The airplane did not have a constantspeed propeller.) 4. (b) Stall speed reduces as the center of gravity moves aft and increases as it moves forward (for a given gross weight). An airplane with an aft CG also flies faster than when it has a forward CG, a consideration for those who race airplanes. 5. The Grumman F4F-3S Wildcatfish (or Wild Catfish) was the F4F-3 modified with Edo floats. It was developed for use at forward island bases in the Pacific where runways had yet to be constructed. It was inspired by the Mitsubishi A6M2-N, a floatplane modification of the Mitsubishi A6M2 Zero. 6. An occluded front (or an occlusion). 7. Are you familiar with those vacuumpowered windshield-wiper motors used in old automobiles? When the throttle is closed and the landing gear is up, low manifold pressure activates one of those old windshield-wiper motors that wags a flagged arm back and forth across the top of the instrument panel like a metronome. It's cute. 8. True. The excess raw fuel washes oil from the cylinder walls and dissolves the oil seal normally formed between the piston rings and the walls. www.aopa.org/pilot AOPA PILOT | 43http://www.aopa.org/pilot
