Nice refresher thanks! A good mnemonic for gyros you can use for ATPL exams is: T R ---- 12 (Turn & Slip - Rate Gyro - Horizontal Axis - 1* Freedom/2 Gimbals) A E I 23 (Artificial Horizon - Earth Gyro - Vertical Axis - 2* Freedom/3 Gimbals) D T ---- 23 (Directional - Tied Gyro - Horizontal Axis - 2* Freedom/3 Gimbals)
Another excellent video. Thank you very much. Working on my CFII now. Did not even consider the parallax effect on the position of the little airplane. Just another minor but impressive detail that I can mention on the checkride.
Hey R Reyes, We really appreciate your kind words. We have done a tutorial on the Turn Coordinator; it is part of our Flight Instrument Essentials Course we offer. Check out PilotEffect.com for more info. Thanks! Mario.
Nice video, but what do you mean the spin axis "relative" to the earths surface, are you saying the gyroscope follows the earth surface? or do you just mean where you are on the earth when its calibrated?..
Karl Steffensen. Yep.... You are correct, the earth must be level.. flat!.. why are pilots oblivious to this fact, a gyroscopic attitude indicator has been used forever... lol
Aircraft air speed indicator (Pitot Tube) question. Why is it so ??? Earth is spinning west to east. At the equator the ground speed is approx 1675 kph. On a still day the air is traveling 1675kph, west to east. A Plane takes off heading to the west, and climbs to cruising speed of 500kph. The plane is now traveling at 500kph ‘relative’ to earth’s speed. In “reality” the plane is moving through the air 1675 + 500 kph. Question 1: How does the air speed indicator compensate for the rotation speed? Question 2: If the plane turns 90 degrees, it would need to subtract 1675 kph (when the air speed ‘relative to the earth’ is the same) from the Pitot tube wafer reading to indicate the correct reading on the indicator. Question 3: If the plane turns 180 degrees (traveling due east) it would need to -1675+500 = total negative 1175 kph (when the air speed ‘relative to the earth’ is the same) from the Pitot tube wafer reading to indicate the correct reading on the indicator. Question 4: Globe beliefs are that it is all relative. How can this be so if the plane can in all 4 directions and get the same air speed reading? Plausible answer: The ground and the air is still.
The video is very antiquated to what a modern aircraft looks like or how they work today. In a modern aircraft the attiude is shown on an LCD or LED Primary Flight Display. The Display has an input from the Inertial Reference System and the Pitch and Roll Attitudes out of the IRS drive the attitude indication. Now to answer your question. On a modern aircraft if you were in a 90 degree pitch up attitude, about 80-90% of the Display would show blue, but the bottom 10-20% would stay brown to help the pilot understand his attitude and vice versa if he was in a high angle pitch down. Also, it is required in a unusual attitude situation (usually greater than about 65 degrees pitch up or 25 degrees pitch down) there would be RED colored chevrons pointing in the direction the pilot needs to correct the aircraft to.
My grandfather says that the actual plane part of the gauge is what moves and the horizon in the back stays still.. He showed me a video and it's true, why is this different?
That is very interesting, you are totally right! Must be a different design, I have never seen an Attitude Indicator designed like that... thank you for sharing. The Attitude Indicator shown in my videos is a typical design.
@@PilotEffect Indeed! I did some research and the antonov 2 is a soviet plane. I should've mentioned that he was a soviet pilot and he flew an AN-2 at one point, which is why it's different. It's a soviet gauge ;)
wooow! incredible man! the best video for gyro instruments i've seen! It really helped me with my aeronautic project, just a quick question, I think you made a mistake, you said that the spinning axis of the gyro is vertical to the earth's suface, but I think you meant it is parallel or horizontal don't you think?
Eccentric Views check out Wolfie6020's videos on the attitude indicator. The instrument has correcting mechanisms that constantly work to slowly adjust the gyroscope to local gravity. The correction process is fast enough to correct for extremely fast flight across a globe earth. The attitude indicator isn't evidence for or against a flat Earth hypothesis.
how does the gyroscope know to spin on an different angle or change its angle as the plane fly's from say Australia to America, over the Earths curve? so that it keeps its level to the horizon... the horizon no doubt changes has the plane travels over the Earths curve. strange question I know but I can't get anyone to answer this.
Eccentric Views, Wolfie6020's video is an electromechanical device. The gyro has small blades that produce the airflow necessary for the pendulous vanes to correct it. For a 100% optical/electric indicator based on a laser ring gyro it is done in firmware.
hey pilot effect, thanks for this great review, i just have a question when it comes down to banking. In some documents, it says: when the carrot is on the right side of the center, the aircraft is banking to the left?!?! and some other documents say the opposite: when the carrot is on the right side of the center, the aircraft is banking to the right? can you please tell me wich one is accurate thanks!!! afoqtguide.com/instrument-comprehension/ or www.personal.psu.edu/lnl/001/faa/faa-h-8083-25-2of4.pdf (p.6-13)
Gone through several videos and texts to and this is the clearest explanation of these instruments. Thank you!!!
Very quick and easy to understand description and graphics.

Fantastic video! I'm pooling resources for my potential job as an FI, and this is perfect.
Thanks Mario for all the great info on avigation...
I have a simulator exam tomorrow and this is very helpful thank you very much.
How did your exam go?
Your tutorials are fantastic! Bite sized morsels with excellent information. Can you guys do one on the turn coordinator?
Hey R Reyes, We really appreciate your kind words. We have done a tutorial on the Turn Coordinator; it is part of our Flight Instrument Essentials Course we offer. Check out PilotEffect.com for more info. Thanks! Mario.
WOw, perfect video, thanks
the video is good... I am an AME student so the construction and working is what I need as well. Could you please make a detailed video on it
Great video! Subscription added.
Great Tutorials.Thanks
Amazing content!
Thanks
Did you mention the pendulous vanes that allow gravity to counteract procession?
Good explanation thanks

Karl steffensen..Yes.. I see your point.. lol..We need everyone to understand the gyroscope..
Aircraft air speed indicator (Pitot Tube) question.
Why is it so ???
Earth is spinning west to east.
At the equator the ground speed is approx 1675 kph.
On a still day the air is traveling 1675kph, west to east.
A Plane takes off heading to the west, and climbs to cruising speed of 500kph.
The plane is now traveling at 500kph ‘relative’ to earth’s speed.
In “reality” the plane is moving through the air 1675 + 500 kph.
Question 1: How does the air speed indicator compensate for the rotation speed?
Question 2: If the plane turns 90 degrees, it would need to subtract 1675 kph (when the air speed ‘relative to the earth’ is the same) from the Pitot tube wafer reading to indicate the correct reading on the indicator.
Question 3: If the plane turns 180 degrees (traveling due east) it would need to -1675+500 = total negative 1175 kph (when the air speed ‘relative to the earth’ is the same) from the Pitot tube wafer reading to indicate the correct reading on the indicator.
Question 4: Globe beliefs are that it is all relative. How can this be so if the plane can in all 4 directions and get the same air speed reading?
Plausible answer: The ground and the air is still.
am i right to say that if a aircraft goes on a 90 degree climb, i should see the whole indicator showing the blue portion only?
The video is very antiquated to what a modern aircraft looks like or how they work today. In a modern aircraft the attiude is shown on an LCD or LED Primary Flight Display. The Display has an input from the Inertial Reference System and the Pitch and Roll Attitudes out of the IRS drive the attitude indication. Now to answer your question. On a modern aircraft if you were in a 90 degree pitch up attitude, about 80-90% of the Display would show blue, but the bottom 10-20% would stay brown to help the pilot understand his attitude and vice versa if he was in a high angle pitch down. Also, it is required in a unusual attitude situation (usually greater than about 65 degrees pitch up or 25 degrees pitch down) there would be RED colored chevrons pointing in the direction the pilot needs to correct the aircraft to.
Nice video! How do you animate everything in your video??
Thank you. I use Blender and Adobe Creative Suite.
Thank you !
keep the vids coming man!!

Can u please do an update on the pendulous veins of the attitude indicator
This currently in the works, I've gotten a lot of requests regarding this topic.
thanks alot :D amazing tutorials though keep up the good work mate ur my FAA for resources :D

does the AI take into consideration of the curvature of the Earth?
thats what i want to know, the uploader never responded to you....

The earth is flat so this is a moot point.
good work brother

is it this same video?
ua-cam.com/video/_MoS5Yw9ZgE/v-deo.html
thanks mate, ill check it out!
thanks, i think i understand now. but thats with an air powered attitude indicator, can you please explain how it works with an electric one?

I couldn't find that video talks about Gyroscopes
how does the gimble "right" itself.. based on gravity acting on the gimble?
Pendulous vanes are used to ensure the
Attitude Indicator gyro is upright... I should do a tutorial on this.
so basically weights that point straight down....?

Um, no it is not.
