I finally know why it takes so bloody long for the IRS to align....temperature and latitude....awesome thanks so much!

I'm only 12 years old and my dream is to become an airbus pilot and wanted to start a journal for motivation this guys helped me to write irs portion in the meantime learned about the ins too.😊😊

Truely one of the best videos about INS/IRS, thank you. Great work

this is the most perfect video about IRS . thank you for making and sharing your knowledge and effort.

took me 3 weeks to gain motivation to slowly start studying intruments, with your help 3 days have passed by and all its coming to a closure, THANK YOU SO MUCH

Excellent video. Very well explained and you answered every question I had about both systems. Thank you

Explicit explanation which clarified the difference between INS and IRS. Very well presented. Thanks and keep it up.

Very Very Useful. Understanding IRS was never this easy. ❤❤❤❤❤ Any video on Navigation displays?

Good presentation, you make me understand about this complex instrumentation. I hope you can present other subjects like meteorology, powerplant and so on. Anyway, this is the best presentation I have ever seen 👏👏

I´m glad you like it! I´m already planning to upload videos about other topics in the future as you suggest!

The best ATPL youtube channel by far! Well done mate

No other video explains better than you, it's the best explanation

Wow, very amazing equipment. Very complex calculations in these systems. Drones must have some cool onboard tactics to play with? 😎 Thank you.

Amazing video. Covered many important topics in a manner easy to understand and remember.

Extremely useful. Thank you for the excellent efforts,

thanks my friend . i learnt something from it

Amazing explaination !

Very nice and fruitful presentation. Thank you indeed.

I love love loveee your channel. Great work!!

This is FANTASTIC thank you!

You are a great teacher!

Exactly what I was looking to learn. Thank you🎉

perfectly explained....keep up the good work sir

This is a well done video and explanation. Thank you

Nice job in correlating the concept and very good presentation mate.

Excellent presentation. thanks a lot.

Very good presentation !

Very well explained. Thanks

You are genius! Thanks for excellent explanation! Now everything is on its place in my head. Thanks a lot. Waiting for new videos

Superb video! Well done, 10/10!

You are the best Chanel in explanation, hope you’ll continue making these videos. And if you can try to discuss other subject such ass radionavigation, principle of flight and those tough ones.

Thanks, good video. Another use of the INS systems in aircraft is for the orientation of satcom antennas used for in-flight connectivity. We grab the data off the ARINC 429 bus or equivalent, depending on aircraft type and use that and other info, along with local rate gyros and accelerometers to very accurately point the antenna towards the desired satellite. In normal operation the antennas also perform closed loop tracking of the satellite to eliminate any offsets that accumulate over the flight duration.

Nice presentation

this videos are helping me big time. Thanks!

Seriously dude, you are a blessing. Thank you (I hate studying from books)

Great stuff. Thank you.

Excellent video!

guys you are the best, please upload more

Thank you soo much !

Very well explained

when you 5 days from your instruments exams at german lba and find this video. thank you so much

That’s an awesome explanation

A million thank for your nice video and the explanation

Excellent!

the best explanation

Thank you.

Good job!😊

very good video ty

The drift rate may well be cumulative, but it cannot be assumed to be constant or linear because in such a case a correction factor could be added to give a more accurate position after the INS had been calibrated. So the performance of INS is frequently rather better than implied by the drift rate. Modern optical systems using laser gyroscope sensors are capable of circumnavigating the Earth with cumulative errors of just a mile or two.

Hi Michael, it is true that the drift rate is variable, since it depends on several factors such as the precision of the initial alignment of the system, the elapsed time, and the maneuvers executed by the aircraft during flight. For this reason, since there is no way to determine the exact drift rate, a predetermined linear conservative value is used as reference.

very usefull thank you so much

AMAZING!!!!

Thank you

Wow, das ist sehr informativ

what happens if you turn on the IRS mid air?

thank u

Very good indeed. One question: With regards to the INS, manual input needs to be performed for initial position. What is the reference source for this initial position? A map location with lat. and long. coordinates?

Hi! Yes, the coordinates of each parking position can be found in the airport charts.

Here is an explanation to a 5 year old. Suppose you are playing hide-and-seek in your house. You are blindfolded. How would you avoid bumping into a wall? You begin at the door. You know the corridor would lead you into the kitchen in about 15 steps. Then, to the right, there is a refrigerator, slightly to it left is an island. Those are the movements and turns recorded in memory. Then you start counting your steps and turns…

Dam, didnt know the IRS was after me in that way too. Lol

I have a doubt. Why IRS is used for navigation if we already have GNSS/GPS system???

I worked on these at tech school. How did pilots get lost before Inertial?

Doesn't the IRS also use GPS data to help correct for drift? Three or more GPS satellites with their atomic clocks can accurately pinpoint location to within a few feet which is much more accurate than .6Nm.

@AviationTheory

Hi Harry, you are correct! In modern PBN systems with multiple sensors, GNSS is used as reference to "re-align" the IRS (Correct for the drift). However, if there is not a GNSS available/installed, the IRS will behave as shown in this video.

13:18 is that frequency or phase difference?

It confuses me. 'The determination of true north (by means of earth rotation) is detected by the lasergyroscopes'. Isn't detected by the accelorometers as either or both of the X and Y accelorometers are detecting the earth rotational force. Of which the amount of X or Y acceleration can be used to determine the present heading and therefore the true north?

@AviationTheory

Жыл бұрын

Hi Danny! Actually, the earth rotates at a constant rate (it does not accelerate), so the rotation can’t be detected by using the accelerometers. Instead, since gyros remain rigid in space once they are turned on, they are able to detect the rotation of the earth in space. I hope it is clearer now 😁

19:40 ADIRS is pronounced (ay-deers)

While I understand how the ring laser system works, I do not understand how the system compensated for the effect of the wind. . . Forget it. I figured it out.

Could you please send me references that you've gotten to build this video up, plss!

Just tell us the truth. This “machine” is powered by magic.

9:40 "Does not need to be on a level platform." WHAT????? Yeah no, it has t be on a precisely mounted platform, not just any jury rigged platform. For instance, no sheetmetal repair can cause the platform to vary from the factory setting. There is a complicated procedure for installing or repairing it's mounting platform.

Surely you could have found a human being to narrate. Lose the synthetic voice.

WRONG, WRONG, WRONG!

The drift rate is 500 m for 8 hours for a military unit

Excellent video. Very well explained and you answered every question I had about both systems. Thank you
