我的理解是,在可以控制转弯下:3 degree per second,2 min 转360的情况下,又不想让飞机上升或者下降高度 ...
那个2min角速度是与仪表上的指针或者飞机符号相关的,飞机符号与R/L那里的小斜线连上了就是标称的角速度。这个飞机符号绝对不是ADI那样反映倾角的。2min与小珠子无关。而这帖子是有关珠子的。不用管那个2min。
The dial of these instruments is marked “2 MIN TURN.” Some turn-and-slip indicators used in faster aircraft are marked “4
MIN TURN.” In either instrument, a standard rate turn is being made whenever the needle aligns with a doghouse.
死记硬背中国式学习FAA的手册的结果就是你不明白为什么FAA手册中会有自相矛盾的地方,这其实来源于FAA编写者的带来的应用学科的不严谨习气。
The inclinometer does not indicate the amount of bank, nor does it indicate slip; it only indicates the relationship between the angle of bank and the rate of yaw.
The inclinometer, similar to the one in a turn-and-slip indicator, is called a coordination ball, which shows the relationship between the bank angle and the rate of yaw. The turn is coordinated when the ball is in the center, between the marks. The aircraft is skidding when the ball rolls toward the outside of the turn and is slipping when it moves toward the inside of the turn.
其实这两种仪表中的珠子都只是一个泡在弯曲的玻璃管子里的东西,没什么复杂结构。但是却有着矛盾的说法,这矛盾来自于说这话时你用不用舵,以及slip或者skid是侧滑倾向还是实际侧滑了。
