The image on that YouTube link makes it look like the airplane is about to hit Mt. Hood in Oregon ...

I'm wondering what it means. High climb rate or high airspeed? High airspeed would seem to be counterproductive.I'm wondering what the implications are of the "high speed climb" they asked and received approval for.
Outside the US that would mean an airspeed above 250kts below 10,000'. In the US the controller does not have the authority to grant such a request (that is reserved for the Administrator). The controller likely thought they required above 250kts due to their clean-maneuvering speed--in such a case, neither approval nor notification is required. The crew may have just wanted the faster climb.I'm wondering what the implications are of the "high speed climb" they asked and received approval for.
Heavy internationals loaded to the brink will routinely require a high speed climb and that is simply exceeding 250 kts below 10. Happens many many times a day just in my airspace and obviously every where else that has them flying around. I'm not an aeronautical engineer but I know there is at least one on here that may be able to explain the whys.I'm wondering what it means. High climb rate or high airspeed? High airspeed would seem to be counterproductive.
And unless they have a restriction on either, is it necessary to get it approved?
They would need to climb slower, or level off, to build speed. Not good with terrain ahead.The reason I raised this question is that I was wondering if the high speed climb request and approval was a factor in the crew's being slow to respond to the turn instructions given. Would there have been a need to delay turning in order to build speed more quickly?

What I find interesting about this is that I just recently saw a "lessons learned" video somewhere on youtube about very similar scenario. But, with a GA aircraft in hard IMC.
I've seen something similar as well and may be what you're referring to, which was a video filmed inside of a Bonanza that came inches from colliding into a mountain. After landing the wingtip was shown to be damaged and the strobe housing was ripped off.What I find interesting about this is that I just recently saw a "lessons learned" video somewhere on youtube about very similar scenario.

Obviously these guys were in IMC. Otherwise they would have looked out the window and taken some sort of action other than flying right at mountain!
Was it daylight, or dark, when this incident happened?
and it was IMC at that time to prob 8-12k - it was pouring down rain all nightGood point. FlightRadar24 says the ATD was 12:25 AM that day. Like a lot of transpacific flights, they departed around midnight.
But if it's where I think it is, there are a whole ****load of lighted towers there.
Nope. Just a button-push or two. The VNAV would manage the acceleration.Would there have been a need to delay turning in order to build speed more quickly?
The problem here was the controller - I remember when she used to work at Brackett - I'm not going to say anything more. But I'm stunned she's [was] working a TRACON.
@Palmpilot it was DARK and wet -
Look at this link - they have an image that shows supposedly how close the airplane came to the towers - these stories are always hyperbole and I'm sure that the image is a telephoto lens - but its still pretty darn close -

I'm just a PPL holder, but I understood the controllers instructions perfectly, and I wouldn't have found myself that close. Further, even in IFR, the PIC is responsible for sanity-checking controller instructions and he should have noticed himself flying into terrain. I think the controller is being railroaded & inappropriately vilified in this case.

The issue is her lack of proper phraseology with a non native English speaker. Add into that her first mistake of "left" instead of "right" instruction.
I've taught several Asian and Middle Eastern students who could barely speak English. You have to be direct and exact with your instructions. You have to use words their most likely to know. Those are the ICAO proper phraseology words and structure.
The backseat quarterbacking would have climbed him above MVA and turned the Southwest dude west bound to get him out of my hair. Once I knew he wouldn't hit the mountain I'd get him to turn on course and out of my airspace.
I think she made the situation worse by keeping him below the ridge line and by yelling the instructions at him.
Found it!
Coming back from NorCal on Wed I received a vector into the hills in the northern San Fernancdo Valley - Foreflight showed me with an impact in 7 minutes- as that ticketed down I broke out of the clouds with a very disconcerting view - 3 min later my TAWS in the 530 chimed - proving that works- just as I was about to exercise my PIC authority to obey the TAWS warning I got a turn - with the beeper going off in the background from ATC. . . .I'm just a PPL holder, but I understood the controllers instructions perfectly, and I wouldn't have found myself that close.
