What is the topic of the paragraph above? a. Aircraft propulsion is a difficult concept to understand. b. External forces must cancel each other out in order for an aircraft to fly. c. An aircraft that remains at a constant velocity will remain at a constant altitude as well. d. Aircraft propulsion involves two objectives involving the laws of motion. e. Thrust must exceed drag ion order for an aircraft to accelerate correct answers d. Aircraft propulsion involves two objectives involving the laws of motion. Choice A can be eliminated, as this idea isn't stated in the selection. Choice B only represents a portion of the subject . Choice C is stated in the passage , but the paragraph isn't solely about constant velocity. Choice E is a supporting concept, not the main topic. Only choice D answers the question. Choose the option below that does NOT support the topic of this paragraph: One of the four forces that affects aerodynamics is weight. The total weight of an aircraft must be factored into the mechanics of flight. Lift also affects flight and must be considered. Weight must include the craft itself, accompanying gear, the fuel load, and any personnel. Carefully assessing weight will help a pilot calculate how to oppose the downwards force of weight during flight. a. The sun weight of an aircraft is important to considered. b. Personnel should be calculated in overall weight. c. The mechanics of flight also includes lift. d. Weight is a downward force in aerodynamics. e. Fuel load cannot be eliminated in measuring weight. correct answers c. The mechanics of flight also includes lift. Choices A, B, and E are stated in the passage . The sun weight of an aircraft is important to calculate, as are personnel and fuel load. Notice that choice E states fuel load cannot be eliminated in measuring weight. Careful comprehension is important when reading choice E. Choice D also supports the idea that weight affects aerodynamics. In choice C, while it's true that the mechanics of flight 7includes lift, that detail doesn't support the overall topic weight. Read the following paragraph, then select the topic: Standard weather briefings can be obtained from a variety of sources, including the FAA. Pilots can obtain abbreviated weather information from briefers to supplement available electronic information. Information that a pilot has previously obtained should be provided to the briefer in case conditions have changed. An outlook weather briefing is obtained six or more hours in advance of the flight. Lastly, it's important to obtain in-flight briefings to monitor ongoing weather conditions during the flight course itself.
