Dreamliner Down in India

Without any WX indications EAST of the airport perimeter it’s harder to perceive that these two extra performance decreases are combining there. If using maximum available ‘derated’, there are then three compounding decreased performance effects that are adding up:


(1)The Derate

(2)The increase in temp with height as opposed to a normal decrease expected.
And keeping in mind here even “fixated on the OAT gauge” would still be latent by a degree-or-two/second-or-two

(3)Any amount of the ‘negative low level wind shear’ itself, almost perfectly reciprocal … the opposing directions either side of a low level transition.

( next will clarify what I actually meant by “confuse” … which is most difficult, tricky)

Who in the @#$! is “fixated” on the OAT gauge, Jesus, this proves in a single sentence that you have no idea what we do up front!
The loss of thrust would be felt immediately and the reaction would be to reference the airspeed indicator to prevent a stall, there is no fixating, I 100% doubt either pilot would have even looked at the OAT, we simply would not care at this point!
I am done with this, you continue to astound me with your lack of knowledge n operation of an aircraft!!!

I should have quoted that “fixated” better … 5 or so posts back someone I think was seriously teasing the issue in their particular context. It was not you! Yes, better leave it … getting a bit much.

One thing I forgot to mention was that over the years studying this topic of inversion shears it has come clear to me that the lack of references for a surface analysis (forensically after the fact or for the pilots checking their WX beforehand) in one direction or another (in this case data abscent toward east) has been the common denominator that I’ve noticed most … at least in a lot of the cases/synopses I became interested in.

What?

[pdw]

Data IS available toward southwest. WEATHER STATION 0310 (ISANAN 83) located on rwy heading approx 15-20nm beyond rwy 23 departure end. That’s “Wundermap”. The only other really useful station I found west of this takeoff is THALTEJ Ahmedabad IAHED42 Jai Ambe Nagar which is about 4-5 NM WNW of the tragedy site.

Except for WX-interpolation via distant stations to the East, there are none that I could find that were within a more reasonable proximity.

Maybe it's just the way he his. I have a family member who behaves a lot like PDW.

I think it's a real dude.
Wind is his jam.
Carry on everyone.

My jam is PC Blue Menu Twice the Fruit Strawberry & Rhubarb.

Incredibly intelligent and spot on! P used to drop by our local airport a fair bit. A kind and gentle person. He has specific topics that bring him a ton of joy and passion!

Truthfully, it’s just dumb gruntwork that bails you out with this stuff. Just takes time always for it to sink-in what’s going on …

How does the ground speed increase per second Triple/quadruple at lift-off here without a ton or two of power added?

Where would all that extra power have come from all of a sudden?

(Using prelim numbers it works out to just-above 1.5kts actual groundspeed increase per second for the 6 seconds prior to liftoff; then has jumped to nearly 6kts per second for those 3 seconds immediately following the liftoff)
