搜救方式
一、 确定搜寻基点:根据1)收到遇险的时间和位置;2)当时的风流情况;3)本船位置;4)本船预计到达时间等确定搜寻基点的位置,位置确定以后,以此点为圆心,以10海里为半径作一个园,该园的外切正方形则定位开始阶段的最可能区域。
二、 搜寻方式:
1、 单船扇形搜寻:用于很小的范围内搜寻。办法如图,以一个航向接近基点2海里后,沿着此航向过基点航行4海里后,右转愚人节的英文comprehensively60°航行2海里后,再右转60°过基点航行4海里后,再右转60°航行2海里后,再右转60°过基点航行4海里后,再向右转向60°航行2海里后,再右转60°过基点航行2海里后,向右30°,然后在以上述方法进行又一次搜寻。
2、 单船扩张方形搜寻:船舶以一个航向过基点航行4海里后,向右转向90°航行4海里,再向右转向90°航行8海里,再向右转向初中英语作文题90°航行8海里,再向右转向90°航行12海里,再向右转向90°航行12海里,再向右转向90°航行16海里,再向右转向90°航行16海里。如图:

1、 飞机环绕船舶至少一周。CIRCLE the vesl at least once.
2、 白天摇摆机翼在船首附近前方低空穿过船首向,晚上闪烁降落灯或航行灯两次或闪烁摩尔斯信号“T” (▬) or “R” (▪ ▬ ▪) (见说明)。CROSS the vesl’s projected cour clo AHEAD at low altitude while ROCKING the wings during daylight or Flash the landing lights or navigation lights on and off twice while during the hours of darkness or Flash Mor Code signals “T” (▬) or “R” (▪ ▬ ▪) (e note)
3、 飞向船舶被指引的方向。HEAD in the direction which the vesl is to be directed.
4、 重复上述动作具有相同的意思。Repetition of such signals have the same meaning.
5、 说明:开关节流阀或改变螺旋桨节距与摇摆机翼有相同招引船舶注意的意思。NOTE: Opening and closing the throttle or changing the propeller pitch also be practice as an alternative means of attracting attention to that of rocking wings. However, this form of sound signal maybe less effective than the visual signal of rocking the wing to high noi level on board the vesl.
四、船舶援助不再需要。
1、 飞机环绕船舶至少一周。辣妞征集CIRCLE the vesl at least once.
2、 白天摇摆机翼在船尾附近后方穿过船尾迹,晚上闪烁降落灯或航行灯两次或闪烁摩尔斯信号“T” (▬) or “R” (▪ ▬ ▪)(见说明)。表示船舶援助不再需要。CROSS the vesl’s wake clo ASTERN while ROCKING the wings during daylight or Flash the landing lights or navigation lights on and off twice while during the hours of darkness or Flash Mo
