Im a fueler and you are right, there's nothing more humbling than to stand in front of these engines. To think these can make over 100,000 hp each, is simply mind boggling. Thank you for showing it to us and also kudos to you who fixes them, and to the engineers that designed them and to the people that built them.

The first time I ever boarded a 777-300 as a passenger, my seat was right next to the engine. I opened the shade and looked out the window and there was a man standing in front of it, as well as a cargo van. Both items looked like they could easily fit inside of the engine. I was floored as to the massive size of that beast. But then, you look around the aircraft and realize just how huge the airframe is and that one of those engines has to be able to power this beast by itself, it's completely proportional to the aircraft. Ever since that experience, I have been a huge 777 and GE90 fan.

Accessories are more of the components attached to the gearbox (IDG, EDP, starter, fuel pump). Valves are more for the pneumatic system, regulating airflow from the engine compressor. As for what fails, well that’s a bit unpredictable, but most common one I have seen is the PRSOV (pressure regulating shut off valve).

Fun fact: There's more to opening the fan cowl than just pushing the PDOS switch. You need to electrically deactivate the slats to prevent anyone from accidentally extending the slats onto the raised fan and reverser cowls.

[@StigAviation]

You’re absolutely correct

[@heavyizthacrown-5842]

The aircraft doesn’t need reversers to stop, however pilots are taught to use the brakes as a last option to slow the plane. First option is to land at or just above stall speed, this bleeds off extra speed while the aircraft is still airborne. Second option upon touchdown, the main gear will touch the runway first while the nose gear is still aloft. The pilot can pull back on the elevators and bleed off airspeed, pilots are taught to keep the nose gear aloft as long as they can, this adds drag without applying brakes. Lastly, reversers can be used. Which creates drag by forcing air forwards instead of rearward. Edit: technically there’s an additional option for pilots, this is to make sure the aircraft not only touches down at stall speed, but to do so at the very beginning of the runway. This gives the aircraft plenty of room to simply roll to burn off more airspeed after all other (non brakes) braking methods are exhausted. 👍🏾

Very well articulated and explained my good sir, thank you so much for your knowledge.

You worked very hard on this video Stig. Thank you so much for posting. I’m certainly going to watch this over and over again before I even begin to ask you any questions about it. Absolutely fascinating. Thank you for putting the effort into making this video and for sharing it with us. GE90-115b. Fantastic engine 🥰 iJeff348

Wow, thank you

[@JulianBalgobin]

Those GE90 engines are amazing pieces of machinery. I wish I could see one up close. An airplane mechanic at LAX told me the basic concept of the jet engine : air is sucked in, then it’s compressed, and then fuel is added, and then it’s blown out the back. But my question is this: why do the engines sound so loud? Their thundering roar also amazes me. Jets taking off from San Francisco fly over my house at about 25,000 feet and even at that distance I can hear the onions roar. Wow are they so loud.?

[@StigAviation]

The good old concept, with a bit of comedy, suck, squeeze, bang, blow 😅 obviously, there’s a lot more involved. But the reason they make that sound is because you have a lot of compressed air being ignited, it’s a very large engine it’s gonna make large sound.

Thank you so much for this awesome video. As for me, a licensed aircraft mech but aren't lucky to be part of any MRO team, I can clearly see and learn something even if we can't work with it on actual basis. Regards from Philippines! ❤️✈️

Glad you enjoyed it! Greetings from LAX
