JAL Options Up to 20 Boom Supersonic Airliners
JAL Options Up to 20 Boom Supersonic Airliners
Japan Airlines (JAL) has entered into a strategic partnership with Boom Supersonic, the Mach 2-plus airliner developer, and has placed purchase options for up to 20 aircraft.
The Japanese flag carrier becomes the second airline after Virgin Atlantic to reveal its support of the Denver-based supersonic airliner project, which is targeting entry into service in the mid-2020s. Together with the 10 options announced by Virgin in mid-2017, the JAL commitment represents almost half of the 76 options received by Boom to date. Three additional operators for the remaining 46 aircraft remain unidentified.
The Boom concept is targeting supersonic travel at current business-class prices by bringing together a 55-seat design using structures, advanced aerodynamics and propulsion technology that was not available in the 1960s for the development of the Anglo-French Concorde, the world’s first operationally successful supersonic airliner. The delta-winged Boom trijet design is intended to rely on a 10% higher speed than Concorde to achieve high use and shorter sector times on 4,500-nm routes, most of which will be flown over water.

"Problem?"
How different is this from the Concorde?
They said it's only meant for over-the-ocean flights.Yea the Sonic booms/noise was the reason they were only allowed to fly into two cities on the east JFK and Dulles. If that's their plan it will have to be approved again I am sure.

It would be cool if supersonic passenger travel returned but its all going to come down to pricing. With super cheap fares are people going to pay hundreds or thousands of dollars more to get somewhere faster? Given how popular shitty airlines are my guess is no.

Sonic booms will be fought tooth and nail and for good reason. They really suck.Yea I saw that but it said most and I thought I read somewhere about a NY to LA route but can't find it anymore. Also this is interesting from the article.
"Notwithstanding the question of whether the privatization of air traffic control is included, Scholl says: “Should an FAA bill get passed early next year, it will almost certainly include something on supersonic transport—and that will be either good, or really good. Everyone wants to make this happen, and we don’t have to change any regulations to see this work.”
The FAA and the International Civil Aviation Organization (ICAO) are working on a global standard for sonic boom that would lift the prohibition on supersonic flight over land. And NASA plans to fly a low-boom flight demonstrator in 2021, which would collect community response data on the public acceptability of a 75-PNLdB (perceived noise level decibel) boom—down significantly compared to the Concorde’s 105 PNLdB"
I am definitely not a fan of privatizing ATC.

Departing or approaching a coastal airport is probably at sub sonic speed.I mean, it has to land somewhere, right, assuming one of those airports on a coast?

4500 nm is just enough range to go from NRT to SFO. the plane can do it in 6 hours, so you could run 3 flights a day per plane
There are people who pay full price for first class on Emirates
That is the target market for something like this, not the poors
High priced, high speed flight has never been for the masses. People didn't line up to use the Concorde, it was for the rich only and the normal people used normal airlines. That's not going to change. The rich will probably gravitate towards supersonic rather than pampered first class like Emirates and everyone else is going to fly whichever airline is cheapest.
Departing or approaching a coastal airport is probably at sub sonic speed.
Assuming that's the total range, 4500nm isn't enough. NRT-SFO is 4453nm, still-air; once you factor in taxi fuel, contingency fuel, destination alternate fuel, final reserve fuel, and any additional and discretionary fuel as needed, you'd blow over 4500nm by a long shot. Even if you weight-restricted it and took advantage of the jetstream going east to be able to do it nonstop, you'd still definitely have to stop on the westbound.
Boom's supersonic airliner is designed for routes up to 10,357 miles (9,000 nm or 16,668 km). On routes longer than 5,179 miles (4,500 nm or 8,334 km), the aircraft will need a simple tech stop to refuel. The tech stop will take less than an hour, and passengers will not need to deplane or even wake up. Tech stop durations are included in all of our time estimates for flights over 4,500 nm.
Of course I assumed as much, but I'm not sure where they would approach, leaving supersonic speed, that the local communities wouldn't experience the boom. I'm just assuming that it's not possible. JFK and Dulles hosted the Concord, right? Those airports are only 20 or so miles, max from the coast.
....actually, I don't know if the boom was heard there when the Concord would land.
"The deceleration from M2.0 is started at about 250 nautical miles to run to JFK, and at an altitude of around 58,000 feet. Concorde becomes subsonic somewhere around 35,000 feet during the descent, with about 85 nautical miles remaining to touchdown."

Subject: Loud Booming Sounds and Shaking in Southeastern Connecticut
To All Users:
The Norwich Police Department and the Colchester Dispatch Center have been
getting reports of a loud booming sound followed by shaking in Southeastern
Connecticut during the last two evenings. The sound occurred at
approximately 8:15 PM both nights and was followed immediately by a shaking
of several homes.
After some research, it is likely that the source of this sound was caused
by a Concord Jet dropping out of supersonic speed over Southeastern
Connecticut around 8:15 PM. The sound from the sonic boom was reflected to
the ground by an atmospheric condition known as an inversion. An inversion
is an increase in temperature as elevation increases. Inversions can
reflect sound waves, and in this case a sonic boom was probably reflected to
the ground by the inversion. Inversions are not that frequent, and only
occur under certain weather conditions.
Of course I assumed as much, but I'm not sure where they would approach, leaving supersonic speed, that the local communities wouldn't experience the boom. I'm just assuming that it's not possible. JFK and Dulles hosted the Concord, right? Those airports are only 20 or so miles, max from the coast.
