1。两种速度的区别: 地速是指飞机相对于地面(以地面为参照物)的速度; 真空速是飞机的绝对速度 2。飞机在地球的什么地方飞行两种速度绝对值相差最大? 赤道正上方相差最大;地极正上方相差最小。 3。两种速度的差值与飞行高度有什么关系? 飞行高度越高,差值越小(???) 4。这几个问题是考你的观察力:A。从北京到LA的飞行距离是多少?B。从北京到LA和 从LA到北京的飞行时间差是多少? (没记住北京到LA之间的啊!) 只有上海浦东机场到洛杉叽的: 飞行距离 6474 miles 沪--->LA :11 小时 35 分 LA--->沪: 13 小时 45 分 |
I live in Irvine. I usually play soccer on Saturday. Do you like to play soccer? If you do, we can play soccer together. I have one team here. |
About #2, the ground speed and absolute speed can be the same at any where depends on the airplane's fly direction. Since the difference is caused by the earth self rotation. |
I live there too. But I do not play soccer. Do you play other games, such as tennis? I sense you are from Beijing. I am from Beijing. Please send a email to stevema1955@yahoo.com. Thank you. |
