A solar flare is an explosion on the Sun that happens when energy stored in
twisted magnetic fields (usually above sunspots) is suddenly released. Flares
produce a burst of radiation across the electromagnetic spectrum, from radio
waves to x-rays and gamma-rays.
Scientists classify solar flares according to their x-ray brightness in the
wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are
big; they are major events that can trigger planet-wide radio blackouts and

A Powerful Solar Flare
Credit: SOHO Consortium, LASCO, ESA, NASA
Explanation: Yesterday, our Sun produced one of the most powerful solar flares in recorded history. Seen across
the electromagnetic spectrum, the Sun briefly became over 100 times brighter in X-rays than normal. Over the
next few days, as energetic particles emitted from these regions strike the Earth, satellite communications might
be affected and auroras might develop. The flare and resulting CME, emitted fro

在walmart看了orion的flare,是用塑料袋密封装着的,包装上写避免潮湿和高温
感觉在天气差、能见度低的情况下,这种燃烧的flare比那些电子的或者反光板都要醒
目,就是担心在车内储藏问题和使用的时候会不会有警察找麻烦
比如温度过高了会不会自燃,放在trunk里被追尾会不会自燃,点一个放在路上会不会
被罚等
有车友常备这个吗?有没有用过的请说下感受

我觉得我落地时flare总是做得不好
以前刚开始的时候是时机的问题,
要么早了,要么晚了
后来练习了一阵子之后,觉得能把握住时机了
但是现在flare的程度做的好像又不好
经常就过了,然后下降率一下变成0,甚至有点轻微的爬升
这样的情况下,再稍微一松,落地就有点重了
经常要弹一下
很少情况下能做到一点弹跳没有,平平地落在地上的
各位都进来说说你们有没有什么小诀窍之类的?

貌似完全是感觉高度的问题。 同一机种飞多了就有感觉.
我觉得low wing的flare容易一些, 飞Cesna就经常吃屁墩。 我的办法是:once run
way made, take a last check on air speed, never look the instruments again,
turn my head a little to left, 用余光看跑道沿外一个wing span的地方, 来感觉
高度. 我个人感觉是, 觉得可以伸脚跳到跑道沿了就pull up.
还有, 我认为flare宁缺勿滥, 手要软, 砸前轮也比磨屁股好:))

是怎么不对?具体什么现象? flare的姿态/时机不好,还是飞机slow flight控制不稳?

如果真是处于平台期。不妨试试飞模拟来练习,换个体验。

If the plane goes up when you pull back, it means you were applying too much
back pressure.
If the plane bounce up after contacting the runway, you were having
excessive airspeed, which means you didn't pull back early enough.
You need to constantly adjust the back pressure during the entire flaring
process. Look outside to judge where the runway is, and look inside to
maintain airspeed. When you enter ground effect, gradually pull back to slow
down the sink rate, but you don't need to aim for a... 阅读全帖

说起好镜头,估计很多人心里的第一反应就是SHARP!SHARP!SHARP!SHARP!SHARP!
SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP
!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!SHARP!
SHARP!SHARP!SHARP!SHARP!(没办法,为了凑足版务关于500字的字数要求,只能
这样了)可以说,锐度这个指标是衡量镜头好还是不好的第一要素,而全开光圈的锐度
又是尤其重要的指标。
当然对镜头了解更多点的,比如跳老,会提出要看边角的fall off,又名vignette,中
文叫失光,俗称暗角。镜头通常都会有点暗角,特别是大光圈镜头全开光圈的时候,暗
角通常最严重。从光学上来说,暗角越大,镜头的素质越差。当然很多追求特殊效果的
都喜欢在后期猛加暗角,这是另外一回事了。
再博学一点的,还会提到抗眩光能力。关心性价比的,还会衡量一下价格,在其他条件
同等的情况下,当然是越便宜越好了。
就是这么一只镜头,某牛人评价它:“A... 阅读全帖

太陽黑子Sunspots其實只是Solar Flare的產物,Solar Flare是太陽內部核融合產生的磁

高能量質子,伴隨著大量Gamma和X射線,具很大破壞力,釋放方向內的行星若無磁場保

終點,磁場最弱,兩地的極光是地球磁場和太陽爆和大氣層互相影響的表現。
Solar Flare對人類最大的影響是電子設備受損,1989年加拿大魁北克大停電就是太陽
爆造成的。人造衛星也最易受到太陽爆的損害。所有衛星的半導體完全不用Silicon而
用Galium Arsenide就是因為Silicon完全無法抵制太陽爆。
Solar Flare對農業影響不是直接,而是容易受損的電子設計會讓需要靠衛星定位或電
子射備的大農經濟受到一點影響。
真正對農業有影響的是全球暖化後的氣候變遷,北冰洋融化後海水溫度下降,洋流流速

'Extreme' class solar flare heading toward Earth
Yesterday, a solar flare set off from the sun, launching a coronal mass
ejection (CME) heading toward Earth, and it's set to make an appearance in
our fair skies this Saturday. While the wave of charged particles headed our
way is much weaker than the most powerful solar flares (like the X28+ gust
from 2003), it ranks in the extreme (X) class, and it's already caused a

来自主题: Pilot版 - 降落何时抬机头的问题
个人理解关于landing:
descend->flare->nose up until stall to touch ground,或者说是,下降-〉摆平机
头-〉抬升机头然后让它逐渐或者stall到接触地面。
目前感觉很难准确判断飞机的高度,在什么时候应该flare然后抬升机头让它自己落到
地面。
模拟器上以前连过,要不就是flare过晚,机头撞地;要不就是过早,飞机过高,最后
stall的时候也是机头撞地。
不知道大家是怎么判断飞机高度然后找到合适的时间、高度来flare的?谢谢

这套练习中, cross wind和turbulence指的是跑道上0~50尺的风, 主要为增加难度用.
既然是在模拟上练习, 飞机保持离地面5尺做就好了. 就是做low approach (low
pass), 飞机处于flare的高度, 但是不flare, 不touch down. 专门练side slip.
也可以叫教练先带你去做几个真实的low pass, 然后在自己搭的模拟机上反复练习.
side slip练习能有效提高cross control情况下手眼脚的协调性.
Side slip练好后(i.e.任何时候飞机都是稳定的,完全受你控制. 再大的风也不会被吹
的乱飘)就可以练习flare. 无非就是在上面的情况下把飞机给拉stall了. 如果上面练
习好了, 这个就比较容易了.
