发帖数: 1 | 1 Autogyros Flight characteristics
Autogyros are often regarded by fixed-wing aircraft pilots as "dangerously
unstable", which is certainly true if one tries to fly an autogyro using
fixed-wing principles. Piloted properly, a autogyro is slightly safer than a
fixed-wing aircraft because it cannot stall. A "stall" does not mean an
engine-out event, it means a fixed wing aircraft is travelling too slowly
for the wings to produce lift. Since the rotor of a autogyro is always
spinning, it cannot stall... 阅读全帖 |

发帖数: 559 | 4 Indicated Airspeed（IAS）这个是空速计测量出来外部动态气压(aerodynamic
pressure)显示的速度值，只和压力有关，是最不准的也是最常用的。
Calibrated Aiespeed(CAS)：修正速度，人工修整了IAS误差，可以从飞行员手册上读出
来，基本作用是来判定速度是否超过法定限制，特别是在低速下。
然后是一个公式：
V^2 = 2*q/p (q是空速计测出的动态空气压力，p是空气密度)
不同高度的空气密度是不同的，所以以海平面空气密度p0为标准就得出Equivalent
Airspeed(EAS)：当量空速。因为这里p0是固定的，所以EAS大小只和动态气压有关。飞机
机体结构强度限度基本上只受到空气压力的影响，所以关于飞机机体强度限度的速度值是
用EAS。
最后是最精确的True Airspeed(TAS):
TAS^2 = 2*((q*T)/(p*T0)) = EAS^2 * (p0/p) * (T/T0)
这里T是温度（单位K,273加摄氏温度），p0和T0是海平面的空气密度和标准温度(1013.24
hPa、288.15K)，这个公式 |

For short field landing you should use the recommended airspeed by POH, not

Once you are on final, maintain your airspeed by adjusting pitch attitude

taking its air speed information from the same equipment that was providing
faulty readings to the captain's ASI, increased the pitch-up altitude and

计算Density Altitude, 考试考过的，
例如机场海拔6000 feet,
高度表设定2892,
当地气温26摄氏度
Density Altitude 计算如下：
Pressure altitude = 6000 + (29.92-28.92)*1000 = 7000 feet
标准气温 ISO temperature = 15 - (7000/1000)*2 = 1 摄氏度
Density Altitude = 7000 + (26-1)*120 = 10000 feet
可见整整比机场原来的高度高出3000feet
高Density Altitude有以下问题：
起飞降落的跑道长度要求要高出很多，
一定要查阅手册，检查天气报告，计算跑道长度要求。
从上面的公式可以看出气温对Density Altitude影响非常大，
有可能的话尽量选早上黄昏起降。
另外True Airspeed比Indicate Airspeed高很多，
可以用E6B计算尺算出，所以起飞降落目视速度要高很多，
但表速度相同，请保持正确的表速。

Strong head wind helps you to put the plane down in the shorter distance

If windshear cause you losing too much airspeed, add full power and go

马来西亚航空，一架波音777-200飞机，飞机自动转向，一度自动爬升至43000英尺高度（正常巡航高度范围是FL250—FL400，25000英尺至40000英尺），发生于澳大利亚珀斯附近海域空中。
上述信息并不来自于MH370，而是来自于马航另一架MH124航班。2005年8月1日，MH124从珀斯出发前往吉隆坡，在珀斯西北240公里印度洋上空发生异常情况。在遭遇主飞行仪表（PFD）数据显示矛盾、自动右转向以及自动超高度飞行（至43000英尺）等一系列问题后，飞行员最终努力将飞机安全降落回珀斯机场。
由于航空公司、飞机型号一致，且事件地点、以及事件具体情况（转向、超高度飞行）与MH370存在类似或关联，关于这一航班与MH370的对比3月24日开始在中文互联网广泛流传。

发帖数: 3395 | 36 To be honest, I don't know. But given the fact that airplane
flies in the air, the density altitude does not come into
play as far as slow-flight/stall training goes. In thinner air, the
airplane's stall speed is still referred to its airspeed, which
is the same regardless of altitude. But the corresponding ground
speed is a lot higher. Which is why you'll need a longer takeoff
ground roll.
I may be wrong though.
I didn't begin my training in a 172. 172 is definitely heavier

飞pattern的话我估计你教练也应该经常会提醒你注意crabbing以保持那个长方形的

可以slip to land，这样更容易保持在runway center line上面。
最简单的提高方法就是找大风的天气叫老师陪你上去练，多练习几次就好了。如果你飞

发帖数: 958 | 46 我现在需要找一个包, 具体要求,
1。 背负系统好 (osprey airspeed，那个就不错了），负重在20lb以内就可以了。
2。 front zip access. (topload 没用）
3。 宽度要有36cm至少，至少可以放下一个36cm X20cm X40cm的长方体。（osprey
atmos 35那个我嫌小，而且包内有点弓）
（不要kelty，不适合我的背。） |
