bro is sitting over the wing. the wing is blocking a lot of noise that would normally be heard. if he's in the front of the plane in front of the engine or in the back behind the engine, it would be quite loud.
I travel on 787s regularly as travel alot for work. All the sounds are different somehow, especially the engine start up sounds straight out of a sci fi movie. Brilliant planes.
Love the 787, lucky to fly on these a few times now, i was always a massive fan of the might 747 with the cf6 engines roaring down the runway, The GEnx do sound great compared to some of the other modern engine types
"Are you more of a fan of the Genx engine or the Rolls Royce Trent 1000?" Glad you asked. In a word, the GEnx. However, as seen in my channel's logo, the GE90-115b ranks #1. Nothing even comes close. My fav aircraft is the B777, but it must have the GE90-115b. Other 777s use the Trent 800, and they're lame (sound-wise) compared to the GE. My favorite pastime is to attach my DAC and headphone amp to my computer and watch aviation videos with good quality audio of the engine sounds. Favorite engine #2: Rolls Royce RB211. (Something tells me that you may know a little about them.) They may not have the same deep growls of the GE90-115b, but they stand alone in their characteristic buzzsaw sound profile. I especially love to watch them in action departing from John Wayne airport in California. Because of the morons that decided to move near the airport in the first place, noise abatement rules are in effect around the airport. Many times the pilots will do a static run up during take off and those RB 211s scream! YOUR VERY INTERESTING title for this video: Thought I was the only av geek who likes really obscure aspects of an aircraft. Apparently, and thankfully, I was wrong. I think the best hydraulic sounds are the flaps and slats actuators on the Airbus A380. They're magnificent, along with that aircraft's multi-segmented ailerons. Two other obscurities round out my list. I am fascinated by the flaperons on the 767, 777, etc. And topping the list of hydraulic audio oddities is the sound of the PTU (power transfer unit) 'barking' sound on the Airbus A320. Thanks for the video. I liked and subbed.
This startup is TOP NOTCH, because the safety demonstration isn't being done at the same time, so you can fully focus on what the plane is doing without some obnoxious flight attendant annoying you
This particular 787-9 was equipped with the new Polaris and premium plus seats, but United has finished retrofitting all of the -9 yet, so there are still a handful with the old config
What an amazing sound. The first time I flew a 787 it already had me. One question: shortly after the engines spool up for take off at 3:32 the whining/high pitched sound can be heard coming back as well. If you listen closely you hear it comes up 2 times shortly one after each other and then stays on. What is the reason this isn’t present at 3:23 when the engines start spooling up, but instead appear 10 seconds later?
Great question! It all depends when the hydraulic system is called into action. After engine spool up, the flaperon on the wing starts moving and the pilots are moving the ailerons/rudders to keep the aircraft centered on the runway
I'm not entirely sure the specifics of the hydraulics but I do know their are hydraulic lines running throughout the aircraft that have fluid in them in order to move many of the hydraulic-powered controlled surfaces
The Hydraulic systems of the Boeing 787 power: -The Flight Controls ( Fly By Wire System) - Brakes ( Electric ) - Landing Gear Actuation - Landing Gear Doors - Nose Wheel Steering - Main Landing Gear Steering All the Aircraft systems listed above are also equipped with Electric Backups powered by : -Opposite Engine -Emergency Generator ( Ram Air Turbine) Note: the Boeing 787 has electric brakes ( powered electrically).
@@muhammadabdullah03 please remember that 787 is equipped with electrically powered brakes system. Every brake assy has 4 Electric Brake Actuators receiving 130VDC from Electric Brake Power Supply Unit.
