The IRS system in one of the most important systems of Boeing 737 NG or Boeing 737 MAX airplanes.
Some people find this system complicated but for me everything in logical there. In this video you will find the detailed information about the IRS System components and operation told by the Airline Pilot.

@flavion1259 3 года назад

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.

@sundar999 3 года назад

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.

@thiagomedeiros2159 3 года назад

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 3 года назад

Yes, that is true 👍

@b2instructor166 3 года назад

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!

@alirezareeasossadat9591 3 года назад

Hello captain,would you make a video about the differences of IRS & AHRS?

@johnbest5817 3 года назад

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.

@srmj71 2 года назад

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 3 года назад

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

@guysterges1382 2 года назад

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 2 года назад

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 2 года назад

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.

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 3 года назад

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.
