2.    Question

题目分析

两个经典题型:

Heading 及 T/F/NG.

做题思路：

先做heading,顺便把T/F/NG 第一题定位。 FAA was created as a result of the introduction of the jet engine.

2.1.  Heading 的分析(14-19)

B段先划掉。因为已给出答案X。所以X也不在选择之内。看heading里选项的关键信息

i) Disobeying FAA regulations. 不遵守。。。。

ii)Aviation disaster prompts action 空难。。。

iii) Two coincidental developments  两个巧合的发展

iv) Setting altitude zones 设定高度区

v）An oversimplified view 一个过于简单的观点

vi) Controlling pilots’ licenses  控制飞行员执照

vii）Defining airspace categories. 定义空域类别

viii) Setting rules to weather conditions 针对天气情况设定规则

ix）Taking off safely 安全起飞

x）First steps towards ATC 

A 段：第一句： An accident that occurred in the skies over the Grand Canyon in 1956 resulted in the establishment of FAA.

ii)Aviation disaster prompts action 空难。。。 

C段：第一句：In the 1940s, ATC centres could and did take advantage of the newly developed radar and improved radio communication brought about by the Second World War.

iii) Two coincidental developments  两个巧合的发展

D 段：Many people think that….. This is a very incomplete part of the picture.

v）An oversimplified view 一个过于简单的观点 

E段：First, ATC extends over virtually the entire United States. Controlled airspace…from 365m above…, uncontrolled airspace

iv) Setting altitude zones 设定高度区

F段： The FAA then recognized two types of operating environments. …

viii) Setting rules to weather conditions 针对天气情况设定规则

G段： Controlled airspace is divided into several different types.

vii）Defining airspace categories. 定义空域类别

2.2.          T/F/NG

20  The FAA was created as a result of the introduction of the jet engine.

A段第一句：An accident that occurred in the skies over the Grand Canyon in 1956 resulted in the establishment of FAA.

所以一场空难导致FAA的设立 而不是由于喷气式发动机

FALSE

21 Air Traffic Control started after the Grand Canyon crash in 1956.

B段 第一句：Rudimentary ATC existed well before the Grand Canyon disaster.

FALSE

22 Beacons and flashing lights are still used by ATC today.

NG. 没看到说现在是否在使用。

23 Some improvements were made in radio communication during World War II.

C段： newly developed radar and improved communication brought about by the Second World War.

TRUE

24 Class F airspace is airspace which is below 365m and not near airsports.

这是很特殊的一道题。G段：uncontrolled airspace is designated Class F.

详细的uncontrolled airspace 的介绍 见E段，在E段，对controlled space 做了详细介绍，那么非controlled space 就是uncontrolled space.

所以看看controlled space的定义：In general, from 365m above the ground and higher, the entire country is blanketed by controlled airspace. In certain areas, mainly near airports, controlled airspace extends down to 215m above the ground. 所以在机场附近215米以上也是控制区域。

因此，24题是正确的。

TRUE

25 All aircraft in Class E airspace must use IFR

G段：The difference between Class E and A airspace is that in class A, all operations are IFR,

所以 25题的陈述是错的。因为 A 须用IFR. 而A与E不同。

FALSE

26 A pilot entering Class C airspace is flying over an average-sized city.

Class C  medium-sized metropolitan airports

TRUE
