Chapeau Captain 🧑‍✈️! One of the most difficult systems to explain! Respekt that you didn’t took your hands of...but rather get things done. Thank you very much! So from my side I would like to encourage you to do more like this technical stuff. Your vid is a balance between theoretical knowledge and also practical presentation. Thanks 🙏

[@flavion1259]

Hi Pilot , for the more uninitiated, explaining how the inertial driving system works is quite difficult. So I explain it this way: suppose we get a passenger into a car and then we blindfold him, when the car starts, the passenger, based on the sensations or perception of the movements of his body, will be able to understand where the vehicle will be at the end of its journey. Well, the inertial driving system in redundancy with GPS is able to allow ocean flights where there is no possibility of having VOR or NDB radio aids.

[@markjackson5333]

As always thank you sir. Always a good way to wind down the day watching your brilliant videos

[@smash_1389]

Very good and detail video. I follow few pilots that are creating similar content as you, but there are not much real examples on real plane like you did here. Please continue with this type of videos as much as you can with this level of details.

Great video! I have watched a lot of B 737 ng tutorial videos and you are the first one to fully explain the IRS System. I think you should do more videos on B 737 ng systems. I have not seen all of your videos but could you do one on the pre flight walk around on the B 737ng.

[@Dani1996ITA]

Thank you very much for this video! Great explanation

[@b2instructor166]

The ADIRUs send inertial and air data (like airspeed, airplane attitude, yaw and roll rates, accelerations, etc.) to the SMYD. So, without this data, yaw movement detection and rudder command calculation are practically impossible. That's why YD disengages with IRU off. Greetings and deep respect from the avionic technical instructor! Your videos are awesome!

[@mohit6945]

[@sundar999]

You are a good teacher Denys! The older type IRS(or INS) used rotating gyros so the equipment was a lot bigger than as now we use laser light instead, obviously. I think it has to do with the speed of light and Doppler effect with movement but I may be wrong.

[@sirvis1]

What in simple words is Required nav perfirmance and Actual navigation performance ?

[@PilotBlogDenys]

The limit that you need to follow and what you actually follow...

[@johnbest5817]

Great presentation. . During normal conditions OK, but when flight conditions are challenging, as in an emergency, with noise, vibration, unsteady motion, I can't imagine how readings and switch and button selection can be accomplished and that would be the time when operator efficiency would be most critical. I wonder how a pilot would specify a cockpit display and control system, carte blanch.

[@FlightdeckTurkey]

Amazing!!!

Ahh my "Pom Pom" is here, ohh love to follow this funny but perfect captain :-)

[@suleimandida6175]

One question what's hard for you landing or take off.

[@PilotBlogDenys]

No)

[@srmj71]

I know this is an older video, but I'll ask anyway. How often would you enter the lat & long on the ISDU, while doing an irs slignment? Great video by the way. I have been studying this system for the last few days.

[@michaelm6950]

Why some aircraft have 2 (787/777) and other 3 IRS (747-400) ? new generation are more reliable ? Thanks for this nice video

[@thiagomedeiros2159]

Hi Captain! What an amazing video, a way to easily understand the IRS. I think that you can't engage the yaw damper switch with the IRS off because the Yaw Damper/Stall Management Computers receives some information from the ADIRUs, and with the IRS off, It would not receive the required information to work. I'm just thinking loud, gotta check the FCOM to see. Greetings from Brazil!

[@PilotBlogDenys]

Yes, that is true 👍

[@Jasim_M99]

hi captain can i select VS in CDU for climb Like 1000 or 2000 in VNAV if i on autopilot after take off plane 777

[@PilotBlogDenys]

Hi, I am not a B777 pilot, sorry I don't know. On B737NG you use MCP to set the V/S

[@Titanium_fighter]

Awesome video, Denis, I love this kind of content that you give us from the cockpit. Thanks You! P.D. I could see a "Zibo mod" picture, very nice, you should try it (Xplane11), this mod will surprise you!

[@malang73]

Pilot Blog, does this instrument large? I ask because I heard lots of accidents on general aviation here in the States. Wonder if many general aviation planes equipped with this instrument accidents will be thing of the past.

[@PilotBlogDenys]

Hi. The ISR system is not very large. Sometimes it is used in general aviation. But it is not necessary. The modern GPS system gives the good daya as well. For example there is no IRS or INS systems on ATR42/72.

[@pewdiecake5340]

u looked so young back then when you flew the ATR😂😂

[@guysterges1382]

well done and interesting video ! One question : How can the 737 navigate when for whatever reason both IRS's are off ? It surely can continue to fly but how will it navigate ? What means remain ? Maybe by using GPS only ? FMC route will still work ? Thanks.

[@guysterges1382]

I found this (in Boeing-Aero): "Loss of one IRU does not significantly affect navigation accuracy. Operation on the remaining IRU should be limited to diversion to the nearest suitable airport. In the event of dual IRU failure, the left GPS true track is displayed on page 3 of the PROGRESS pages on the CDU. This serves as a tertiary backup for the airplane heading or track and an update to IRS ATT mode."

[@guysterges1382]

and also this (from 747 pilot): "The GPS (alone) will not drive your Map display. You will have to figure out which way you are flying (the hard way). You can enter a HDG into the IRU's, periodically (from your whiskey compass), when they are in ATT mode, but still no Map. You will have to use dead reckoning and also fly manually (no A/P)" So i think thats the answer to my iniial question.
