I will only believe what our resident aviation expert, GT has to say

Well you can have the benefit of Byron Bailey's view in today's Australian

[Street garbage]

I have seen 4 different photo's in articles describing the incident. A330, 787, 744, A380. Still waiting for the photo of the 737. Glad to see so many experts in journalism. I shouldn't be disappointed though, some of the propaganda from the Street last week describing the Super Constellation had a photo next to it of an Avro Lancastrian.

"We were absolutely certain we were going to die."

Well, you were absolutely wrong, weren't you!

[Capt Fathom]

"We were absolutely certain we were going to die."

Well maybe you should have thought of that before you got onboard!

[wheels_down]

Geez the general public don’t have much faith in Aussie pilots these days do they?

[Ken Borough]

Where are the ambulance chasers?

[compressor stall]

PM on Auntie tonight had a short article on it. It presented the hysterical commentary then countered with another view that was quite the opposite - short and over in a few seconds.

Admittefly the QF tech pilot presented the facts involving pitch not roll so it’s possible the hysterical one was at the back and the calm one was in the middle.

Ummm - you ARE going to die!!

I have been in the wake of an overflying A380. It's pretty awesome and lasts for a seemingly long time.

Do they not apply SLOPS on the pacific?

[Street garbage]

QF have released data from the incident, there was a 3 degree pitch change during the incident.

SLOPS is advisable and a prudent measure for a thinking pilot.

avherald as mentions up to 3 degrees of pitch change (ie +/- 1.5 degrees) and 100 ft of altitude.

what I would like to know is why there was only 1000 ft separation so aircraft flying the same direction.
Incident: Qantas A388 and Qantas A388 over Pacific on Jun 10th 2018, wake turbulence causes altitude deviation

It’s not unusual for the QF 8, 12, 16, 94 and a couple of United jets to all end up close to each other over the Pacific, due to departure delays and the fact that everyone is chasing the same winds. Crews will accept non-standard levels in an effort to improve fuel burn if their preferred altitude is blocked.

Slop left or right depending on the wind?

SLOPS works well, if you are on an airways, not flying a FLEX/ UPR Track.

[DirectAnywhere]

No point offsetting when everyone’s flex tracking. You have no idea where the other aeroplanes are going. Very few aircraft are on airways across the Pacific these days except US domestic jets between Hawaii and the mainland.

[megan]

A question from the curious. I presume the trailing aircraft would be aware of the aircraft in front and above. To what range is the TCAS good for? In the offshore helo world personally used to use the radar to keep tabs on traffic ahead, which were the ones of interest, surprising good with tail on aspect,

[Snakecharma]

I very rarely see TCAS traffic when enroute between Aus and the US, and given we are on CPDLC we have no real awareness of other traffic

We are inevitably applying a version of offset as we get weather deviations around the usual pacific weather.

sounds like a whole lot of nothing to me, well apart from “my life flashed before my eyes and I was certain we were going to crash” when I heard the sound of a tray of glasses crashing in the galley.

And t_cas not sure I agree with your assessment, and I am most certainly a thinking pilot
