1、Why is it necessary to increase back elevator pressure to maintain altitude during a turn?To compensate for the______.
答案:A
解析:平飛轉彎應保持高度不變,故垂直方向上的升力分量應與重力相等,升力與重力的合力水平指向飛機空中軌跡的圓心。因為升力有水平方向上的分量,所以在轉彎的時候應主動帶杆或加油門,使飛機抬頭,迎角增加,速度增加,升力增加,以抵消豎直方向升力的損失。屍 產生坡度越大,需要補償的升力垂直分量越大.
A.loss of the vertical component of lift
B.loss of the horizontal component of lift and the increase in centrifugal force
C.rudder deflection and slight opposite aileron throughout the turn
2、What is a purpose of flight spoilers?
答案:B
解析:知識點:主考點2.1.4.6(擾流板攙縱)
A.Increase the camber of the wing.
B.Reduce lift without increasing arspeed.
C.Diret artlow over the top of the wing at high angles of atak
3、For which purpose may flight spoilers be used?
解析:飛機擾流板分為飛行擾流板和地面擾流板。飛行擾流板可在空中和地面工作 ,地面擾流板只能在地面工作。飛行擾流板的功用:輔助副翼進行飛機橫滾操縱;作為空中減速板使用;在副翼卡組時實現飛機的應急橫滾操縱;在地面塔阻卸升,幫助飛機剎車減速。地面擾流板的功用:在地面增阻卸升,幫助飛機剎車減速。擾流板應在起飛前收好,否則推油門起飛會發出起飛形態警告。知識點:主考點-2.1.4.6(擾流板操縱)
A.Reduce the wings' lift upon landing.
B.Increase the rate of descent without increasing aerodynamic drag.
C.Aid in longitudinal balance when rolling an airplane into a turn.
4、Which is a purpose of ground spoilers______.
解析:飛機擾流板分為飛行擾流板和地面擾流板。飛行擾流板可在空中和地面工作 ,地面擾流板只能在地面工作。飛行擾流板的功用 :輔助副翼進行飛機橫滾操縱;作為空中減速板使用;在副翼卡阻時實現飛機的應急橫滾操縱;在地面增阻卸升,幫助飛機剎車減速。地面擾流板的功用 :在地面增阻卸升,幫助飛機剎車減速。擾流板應在起飛前收好,否則推油門起飛會發出起飛形態警告。知識點:主考點-2.1.4.6(擾流板操縱)
A.Reduce the wings lift upon landing
B.Aid in rolling an airplane into turn.
C.Increase the rate of descent with out gaining airspeed.
5、What is the purpose of a control tab?
解析:控制片用在一些運輸機上作為通常使用液壓操縱的飛行操縱面的手動輔助。手動輔助開啟調整片, 也叫手動恢復。通過移動操縱盤, 駕駛員可以操縱控制片,從而引起飛行操縱面的移動。知識點:主考點-2.1.4.1(飛行操縱系統的組成)
A.Move the flight controls in the event of manual reversion.
B.Reduce control forces by deflecting in the proper direction to move a primary flight control.
C.Prevent a control surface from moving to a full-deflection position due to aerodynamic forces.
