How is a confusion possible between Western and Russian …
2018年5月23日 · The exact same source of confusion often arises when a pilot who is used to focusing his attention mainly on the (Western style) attitude indicator tries to fly primarily by reference to the "turn coordinator"- where the moving thing is the airplane, not the horizon. It is very common for relatively inexperienced pilots to react in the "wrong ...
gyroscopic instruments - Why does the attitude indicator gyro not ...
2020年9月20日 · No outside force is applied to the gyroscope until the mechanical limitations of the instrument are reached. Once the mechanical limitations of the instrument are exceeded, the attitude indicator may tumble. In the case of the Directional Gyroscope, on the other hand, it is constrained to move freely only upon one axis relative to the fuselage.
flight instruments - How are attitude indicators kept accurate ...
2015年6月29日 · The attitude indicator is very important for any sort of instrument flying, so it must be accurate at all times regardless of the plane's movements. I presume that the indicator would be connnected to a gyroscope. However, gyroscopes drift, and a drifting attitude indicator would be pretty useless. Of course, you might have a reset button, but ...
flight instruments - How does one reset an attitude indicator that ...
2015年4月19日 · I was up flying today – VFR – and the attitude indicator tumbled. It's a 6-year-old RC Allen 22-7, without the ability to cage, so I just wound up letting it be all off-kilter until things stabilized... which took almost an hour. The vacuum was in the green the entire flight, and at no point was I doing any wild maneuvering.
flight instruments - Understanding how Attitude Indicator works ...
2023年8月18日 · The instrument reading is directly derived from a gyroscopically-leveled, essentially precession-free, gimbal-mounted sensor. There is no binding of the freely moving instrument sensor within the instrument case. This excellent video by Ryan Anderson explains clearly the operation of the freely-moving instrument sensor.
flight instruments - What is the difference between Turn …
2015年7月2日 · Attitude Indicator. It shows your attitude (nose up / down, bank left / right) relative to a horizontal surface. Basically, it tells you the orientation of the plane if someone were to take a photo of the plane from the outside at this very moment. It does not tell you which way you are going (e.g. you can be nose up but descending). Turn ...
Is Turn and slip indicator a good back-up for the attitude indicator?
2019年11月27日 · The airplane symbol on the attitude indicator reaches the second white line on "ground" on the left side. Conclusion: the turn and slip indicator and the attitude indicator show more or less the same angle on the roll axis. The differences are: turn and slip indicator is limited to a specific angle, the attitude indicator works beyond this angle.
Were the original gyroscopic artificial horizons "upside-down"?
2021年11月8日 · $\begingroup$ Attitude indicators (AIs) in Soviet Bloc aircraft operated opposite to the way western AIs worked, and cause numerous accidents in pilots converting to western designed aircraft after the fall of the Soviet Union. In these AIs, the background remained fixed, and the little aircraft moved around.
flight controls - What is the exact meaning of "attitude", does it ...
2017年3月1日 · Attitude is visualized using an attitude indicator (aka artificial horizon): Attitude indicator, indicating 5° right roll and 10° down pitch. In some applications attitude may include heading as well, and thus becomes a synonym for orientation in space using the three angles: heading/yaw; pitch; roll/bank.
faa regulations - When/How may I replace the Turn Coordinator …
The attitude indicator contains a gyro mounted on ordinary mortal gimbals, which can only accommodate a limited range of pitch and bank angles. A steep spiral can easily cause the gyro to tumble, whereupon it will need several minutes of …
