Enacted in August 2011, the Cross-State Air Pollution Rule was supposed to
reduce air pollution emitted in one state and carried downwind to another.
Under the Clean Air Act, if pollution from the upwind state is causing the

为远处有飞机飞来，被塔台(Class D)叫short approach，立马收油门降
flaps歪歪扭扭地forward slip，结果高度降得不够，还剩30尺的时候都
已经过了number了，告诉塔台我只有go around。
好吧，结果我在下一个downwind快base时又有飞机来，已经在4-mile

这次没有辜负希望，算得刚好，nice touch'n'go。 |

进Downwind听见一架飞机已经两次go around了, 有人对他说你要是还降不下来, 就去BJC试试吧.
俺一转上Base, 猛然发现地速是相当的快阿, 这个弯还没转完, 就已经错过跑道了, 等转向final, 飞机都偏到另一侧的downwind位置了. 拼命往回飞阿, 到了thershold, 才飞到正确的航线上,而且有很大的crab角度. 172的Demonstrated crosswind velocity是15节. Side slip + crab把飞机降了下去,接地是绝对的greaser.
看来模拟还是挺有用的. 飞模拟的时候, 15节侧风算热身, 而且经常从一些奇怪的角度飞final, 对今天的情况是相当有帮助的. 以后要多练习些GRM. |

excellent tee shot and an accurate 3 wood approach shot, put the ball about
12 feet to the pin, a smooth putting stroke put the ball into the hole with
2 kids' observation.
Actually, the amazing thing is about the two kids. I guess they are just as

downhill的还有360嘛左右的距离，使得450码的par 4 也变成 driver + wedge.
特别是今天下午这轮，非常非常solid的ball ——striking， 4个par 5, 最短是510嘛

Not only those guys hit balls freaking long, 6800 with 15mph+ windy from
south (which means 70% of holes played downwind) were like Driver + wedge
chipping.
I witnessed Chris chipping in at the most difficult hole,#11 and hit the

发帖数: 10701 | 36 for those par5s, yah, normally, there are about 530 yards ,560/590 for some
downwind holes, i can't reach by 2 anyway ( a bit short always, like 5/10
yards). my approach shot, normally, uses the "go for it" strategy. it ends
up some chipping/pitching from tough spots. you know, closer the green, more
trouble around.
i have much more birdie chance from a dog-left par5 which i have to layup
for my 2nd shot. and i play my wedge for the 3rd shot to get closer.
so.. it's how it is. |

其实看carry distance (CD) 不就可以了吗？
downwind, true CD 减 wind speed * 2 yard
headwind, true CD 加 wind speed * 2 yard
250 yard carry => 105 mph club head speed at impact
club head speed 差1mph, carry 差 3 yard.
driver carry sometimes hard to measure.
5iron/hybrid carry 190-200 roughly ---> driver can carry 250 - 270 |

经常前面的家伙飞big pattern，而我在练power off landings,所以经常被要求extend
downwind 。。。
空管里嫩的也多，一次taxiway z有事儿，有些cones在上面不让走，而ground里甜蜜的
女声说taxi to 31R via zulu,旁边的教练立马说so you wanna us go thru the cones
? 女声磕绊了一会儿改口说to 31R via yankee。。。
还有一次马上要落地31L了，tower突然说change to 31R,教练难以置信又确认了一遍，
tower确认了，我们立马在低空低速的时候掰到右边，这时候听到radio里screaming "
no!"。教练骂道“shit!",我们感紧加油go around。原来31R final上我们后面还有一
飞机。这类事儿还有好多，所以以后真不能太信空管。 |

发帖数: 3395 | 45 两年加一个礼拜啊……飞了总共一百二十多小时。不过今天总算过关了。
从ITH起飞的时候天气不是特别好，有小雨，还好celing有7000，FA说整
条路线VFR。要了Radar Following，结果起飞后才给Squawk Code，叫我
Contact ELM Departure，我说，有Departure Freq吗？来回两三次，我
还把Squawk号弄错了一位。ELM告诉我对的Code。然后往东飞到BGM。
Level 5500。
过了BGM，找到了我选的Alternate Airport CZG，考官把我油门关了，说
咋办，我一边忙活，他一边取消了Radar Following，我就缓缓的滑到了
CZG上面，地面人说用Runway 21，我转了一圈，到Downwind高度刚好是
1000AGL，然后就Dead-stick, Forward slip，这在ITH练过至少10来次，
最后降得还是满轻的。
然后就是模拟Soft & Short，再爬起来之后就是Ground-Ref-Maneuver，
Steep Turn，Slow Flight，Instrument。觉得考官成心想放 |

教练说只要这次连做3个漂亮的起降,就放俺solo.这几天在模拟机上狂练，已经基本能
稳定的在15节直接侧风和severe turbulence的情况下做标准stall-down landing.
给 FSS打电话做weather briefing. 情况良好,科州平原地带都是高压区,没有airmet/
sigmet.早早来到机场,做好了飞行前检查.居然只剩3个小时的Tachometer time就要到
100小时检查了.而且航校说貌似Hobbs也出问题了,比实际时间多,叫教练注意用手表核
对时间.
于是大家就上了飞机, 开车，滑行，试车一切正常.基本没风,就从静风跑道33起飞.刚
到300AGL做了起飞后检查就发现今天还是有点轻微turbulance的,这种情况在夏天的科
州倒也很正常. Downwind, base, final飞的都很不错. Final approach那是相当的稳
定. 本以为这个漂亮的降落是肯定的了,没想到flare的早了点,落地比较重. 这个降落
基本是不行的,接地点离跑道的 |

的验算.具体飞行方案是Erie到Sterling，再到 Greeley，最后回Erie. 第一段(EIK-
STK)有90海里,第二段(STK-GXY)60海里,最后段(GXY-EIK)30海里.各个check point都早
已经测量完毕,带入数据计算即可.一般我尽量保证能同时用至少2个地面标志物来定位,
同时再用1个VOR做备份.这次对油量进行了比较仔细的计算,因为教练特别要求不许用
full tank起飞,如果发现不够了自己加.这必须算清楚了,不然飞在空中没油了可没有7-
11.
早上08:28开车,08:37起飞.飞上downwind,然后从机场中间正上方飞过,同时开始卡表计
时.保持058航向,6800MSL高度.这时还在 Denver的Class B下面，不能飞太高. 稳定以
后,马上呼叫Denver radio,激活flight plan.顺便问一下能否提供VFR flight
following. Denver radio叫我在125.9上联系Denver center. 于是呼叫De |

本人评选你为本周最佳落地，呵呵
去BJC试试吧.
等转向final, 飞机都偏到另一侧的downwind位置了. 拼命往回飞阿, 到了thershold,
才飞到正确的航线上,而且有很大的crab角度. 172的Demonstrated crosswind
velocity是15节. Side slip + crab把飞机降了下去,接地是绝对的greaser.
度飞final, 对今天的情况是相当有帮助的. 以后要多练习些GRM. |

不过如果真是连续go around两次的话, 我要找个地方hold一下, 考虑分析一下当前的
情况.
其实当时我在Downwind上听到这个消息以后,基本就把降BJC做为一个备选方案了,因为
我知道BJC的跑道更长更宽, 离这里不到10NM, 而且它的跑道是11-29. 如果真go
around两次, 我也会飞去BJC的. |
