@TheFejfAviation 7:55 - 8:05 - I notice how in that video cutoff, there a change in aircraft sounds, which I've noticed anyway when aircrafts climb to higher altitudes. The motor-like sound seems to be mainly at liftoff and during the initial climbs, but then the jet sound (separate from motor sound) I've always noticed gets louder as aircraft keeps climbing higher up. Is the increased jet sound because the jet power is being turned up to higher levels as altitude gets higher, since speed of aircrafts at higher altitudes continue to increase. I know they are up to over 500 mph once reaching 35,000 feet during airline flights. But as for the motor sound being turned off before plane gets that high, is the motor sound a part of the engine that simply helps lift the aircraft upwards but that's it? Where the separate jet sound is the speed of aircraft? Basically, two separate sounds and two parts of the engine, one for lifting and one for speed? That would make sense since once plane is at cruising altitude, the motor sound is gone but jet sound remains all flight, and at its loudest at cruising altitude
@@alvexok5523 From what I've heard, they actually decrease the throttle at cruise altitude. That "motor" sound you hear is vibration caused by the tips of the fan blades going supersonic, which only occurs around 85-93% throttle. I believe during cruise the throttle is set around 35-45%, so you don't hear the hum/buzz/growl. I would also like to add that at higher speeds, you are less likely to hear the "motor" sound even if the engine is in the 85-93% range because the high speed of air rushing into the engine reduces or smoothes out the supersonic shockwaves at the fan blade tips.
Love this old girl, she sings like a beautiful morning song bird. You're very lucky to get her on such a short flight. Most of the time its 737s or 319s. While those planes are great, they lack the uniqueness that makes the 777 so special imao.
Great video!!! Thanks for sharing your adventure and letting us come along for the ride! Beautiful takeoff on a beautiful aircraft from a beautiful airport! All the best from the west coast of Florida USA!!!
Stupid question: Is it common for such large aircraft like the triple seven to be put on such short domestic routes? I'm guessing it's because it's a heavy demand route and it's also both United hubs? Just wondering.
Its pretty common for US airliners to use wide-bodies on domestic routes. The reasons can vary but some are due to air craft re-positioning, high demand routes, training purposes & premium routes. Normally they will also flow between that airlines hub airports. You pretty much had the right answer.
Yes the 777 goes transcontinental on United for demand purposes. Not for the range. I’ve been on the 777s before for domestic routes, and it is a nice plane for a quick 5 hour hop!
I liked the views. However, I have one question at 7:55 - 8:05, the video was cut during that time, and it seemed like inbetween that cut the aircraft moved some distance according to the change in sound of the aircraft. Yet it almost looked like the aircraft was almost in the same place, it hardly moved forwards at all since we were looking out at the same bay from such a similar angle. But according to aircraft sound, some time passed during that cut. How could all that time have passed yet it still seems like they're still in the same spot?

Very powerful take off, and sound of the Pratt & Whitney PW-4077 turbofan engines.
The engine spool up is music to my ears. Awesome video.
Thanks!
The buzzsaw calms me down

@psquareflight Yeah, jet airliner aircrafts have different sounds. See my question above to @TheFejfaviation, what do you think?

Lovely oldschool sound of 777 fan ♡

Nice! Best engine ever! The PW4000!
I think this is the GE90
This didn’t age well.
@@robbie19143 it’s a PW4000
@Qatar airways Airbus a350 it’s a PW4000
sounds like A350's Trent XWB
Get to fly on this baby this summer super excited
Awesome! Enjoy and safe travels!
@@TheFejfAviation thanks
This sounds like a V2500 but lower pitch
Something about jet engine spool ups just calms me down. Great video bud
WHen I'm not home, my computer turns on and plays these vids and wishes it could fly.
Wow sounds like no engine derate in the climb
Great video!!! Thanks for sharing your adventure and letting us come along for the ride! Beautiful takeoff on a beautiful aircraft from a beautiful airport! All the best from the west coast of Florida USA!!!
4:12 What the fan on my computer sounds like when I fire up my flight sim
🤣
Awesome takeoff!!
Nice sound
Very Good video. Thank you.
Trip 7 is a monster.
This makes people comfortable
with pratt and whitney
Best part is at 4:14😍 Seems by the way this aircraft is currently not in use (parked). Hope she will be back again in the skies!
It is now flying
Amazing...
This was before wheels started falling off Triple 7's

is this equipped with the new polaris product?
Awesome 👍
For a short flight on a shorter runway it was a bit of a long roll. Guessing it was loaded.
never heard of the Pratt and Whitney engine
👽✌️. 👀🚁💨. 🚁🚁🚁🚁🚁🚁🚁
PW engines are a bit smokey lol
GE90 best motor
True but these are P&W
@@TheFejfAviation I prefer the TF39
And I'd just say these are PW4090s
The sound is the same
@@flushometer19_8 agree
@@flushometer19_8 kinda similar, but a bit different

Powerful take off....? I wouldn’t want a weak less powerful takeoff. Just saying.
Slightly long takeoff roll
