- United Airlines Boeing 757-200 takeoff from Denver International Airport to Kahului Maui. KDEN-PHOG. N543UA. Seat 6A First. This flight was over 3/4 empty. This bird was manufactured in 1991.
Apparently the "buzzsaw" sound is the main fan blades exceeding the speed of sound and the pressure waves interacting with the outlet guide vanes. Of course, the sound goes away when the pilots disengage max/take-off power.
United at one point had 3 subfleets of 757-200s, those being domestic, PS, and international. There are key differences between them, and not just the interior configuration. Only the international configuration is still operating today.
This looks to have been the domestic configuration with 24 recliner seats and 158 economy seats for a total of 182. These were all delivered to pre-merger United, had PW engines, most lacked winglets, and were not ETOPS rated. However, this one was ETOPS rated. These were all retired by 2017 and replaced by the 737-900ER.
The PS configuration had 28 lie flat sets and 114 economy seats for a total of 142. These were also delivered to pre-merger United, had PW engines, but did have winglets, and some were ETOPS rated. These primarily flew on premium transcontinental routes, between New York/Newark and either Los Angeles or San Francisco. They were retired in 2020, and internationally configured aircraft (including widebodies) are filling in the gap, presumably until the A321neo and Max 10 arrive.
The international configuration has 16 lie flat seats and 160 economy seats, for a total of 176. These all originally flew for Continential, all have winglets, all are ETOPS rated, and they have RR engines instead of PW. All but one are still operating today. The one that was retired was damaged beyond repair in a runway overshoot at Newark.
I love that pw2000 engine sound.
30 second take-off roll at 5k' elevation and not in winter. Not bad.
Amazing video!
Sounds like a Montgomery Hydraulic Dry Powered Motor for the Elevator going up!!
The last flight for this tail number is listed back in 2016. Looks like the bird served her time and went off to the plane graveyard.
Amazing video! You guys really were light, that was a really early rotation!
I think the engines were pushed to full power.
They are probably actually fairly heavy, flying to Maui. 757s are extremely overpowered, which is why they are great for airports that are high and hot, (high altitude, hot weather), like Denver and Mexico City to name 2. That's also why Denver has the longest runway in the US.
Muito bom o Vídeo
parabéns 😆😆😆
No I think its not a rolls royce rb211 its a pratt and wittney pw2000
A PW2000 will sound much different than a RB211
@@ag6371 Only the ex-continental 757's in UA's fleet are equipped with the RB211. The original United 757's all have PW2037's.
That was no buzz-saw; that was a Tony Iommi low-string guitar drone!!
this buzz sounds like the roar of the aer lingus a320
you could of just said a320 no need for the aer lingus part. also doesnt aer lingus use a319s?
Average Alien it uses a321 too
Every A320 with CFM56s sound like this
No winglets?
Brian James duh it's a 757
Why say duh Derick? most 757's do have winglets now
@@derickvo317 Duh 757s have winglets too. duh research before you answer. Duh you look like a fool
