A Roaring Tailwind Propels China Airlines Flight to 826 MPH Over Pacific and Other Record Flights

Submitted
China Airlines Flight 5116, a Boeing 777-200LR, achieved a remarkable speed of 826 mph as it journeyed eastward across the Pacific Ocean on Thursday. The flight, originating from Taipei, landed in Los Angeles more than an hour ahead of schedule, thanks to extraordinarily strong tailwinds. (www.airguide.info) More...

and once they arrived, no gates available,, so waited for 2 hours on the tarmac, kidding

True I’m sure about gate but mor likely 2 hours waiting for luggage!

I’ve been onboard a B-777F traveling at 707kts groundspeed(813mph). Can’t post the picture however.

I once flew my Kitfox Airplane “backwards” in the face of 45 KT headwind.

I tracked a Citation X at a ground speed of well over 700 mph once. I knew the pilot and was following his trip on FlightAware. This was maybe 15-18 years ago

You want to impress me? Fly a pressurized Cessna P210 on a transcontinental flight with 3 planned stops, but do it non-stop with fuel to spare.

Yes, Gracey, it has been done.

I once experienced this on a flight from China to SFO.
We arrived an Hour and 20Min. Early and were diverted to OAK (Oakland) on the east side of SF Bay.
Sat there for an Hour locked up with one engine running before taking off for a 5 mile flight to SFO.
There was no Gate available at SFO for an early arrival.

Same thing going from Chicago to Madrid years ago. Arrived in MAD one hour ahead of schedule and airport was closed with only three or four people around and no custom officials, no bag handlers, nobody. So we had to wait one hour until there was someone to open everything. That was a United flight.

I’m flying east over the Pacific in a month. I hope it’s speedy too!

"A British Air Boeing 747 flying near Greenland reached 825 mph in February 2020, setting an informal record."

One word: Concorde.

Just when you thought there were no more records to be set, BAM! a new one is reached. Definitely fair winds to the crew of this flight. A tip of the cap to them!

OGG/PDX - 4hr28min At one point earlier this week, reached GrdSpd 700 mph.

I asked blancolirio to do a video and explain how planes flying over Mach 1 do not break the sound barrier.

Mach is an relative measure, the speeds that these jet liners in the article are discussing is "ground speed". the indicated airspeed that is displayed on the instruments will be the same as it always is. conversly when they head west the "ground speed" will be less due to headwind. so if an ailiner does 450 kts with zero wind and it gets a 100kt tail wind the airplane will now be doing 550kts across the ground. and with a 100kt head wund it will now do 350kts across the ground. Indicated and true airspeeds will not be affected

On June 11,1981 I flew a Piper P28 Warrier from Ukiah, Ca to Oxnard, Ca and averaged 185mph ground speed.

I thought the air speed record for a commercial jet was for a long time held by a BA Vickers VC-10. However, that was recently broken by a Quantas B787-9 I believe, or was it a Norwegian/Norse airframe

c'mon folks, seriously?
Ground speed = air speed + tailwind or
Ground speed = air speed - headwind
If you're having trouble sorting this out, as many of the repliers apparently are, just think about why aircraft land upwind instead of downwind.

Hmm, my recent flight from BKK > ICN > MSP > BNA still took 32 hrs!

The plane’s speed exceeded Mach 1 (767mph). At what speed does the 777 risk breaking up?

Airspeed is the critical factor, not speed across the ground, in respect of exceeding the max design speed of an aircraft.

No disrespect to the original post, but I'm always amazed how people can't make the difference between airspeed and ground speed...

Besides, the Mach number is not a fixed value, as the speed of sound varies with air density and temperature. And of course, how loud one screams :D

Okay, I'll bite. At what *airspeed* does the 777 risk breaking up? What would this reported high ground speed equate to (roughly) in airspeed? How close to "danger" was this aircraft while flying at this speed? Was it even in danger at all, or was this perfectly safe?

Every aircraft type has a max airspeed. It is referred to Velocity Never exceed (VNE). It is to be found in the pilot operating handbook (aircraft manual) for the relevant aircraft. You may be able to google the 777 specs.

Found the following info, as vne doesn’t apply to transport category aircraft.

Vmo/Mmo for the 777-200 are 330/.87. (330 knots indicated / Mach 0.87)

Of course Vmo is less at altitude higher than 30,500 ft ( KIAS equivalence of .87).
