Heres an idea: How about 2 kinds of engines on the plane? The overture weighs about 170,000lbs apparently. Why not have one high bypass engine, mounted in the aft fuselage (L1011 style) with some kind of closeable intake door. Something in the 30-35,000lb thrust range would probably be sufficient. ...

Jump to postI spent a weekend in San Diego a couple weeks ago. Witnessed multiple F-35, F-18, and C-40 (737ng) takeoffs from NAS North Island. There is absolutely no comparing the noise level between the fighters and the airliner, even when the fighters had their afterburners off. Have noticed the same thing s...
Jump to postThey are using afterburner on takeoff which more than doubles the loudness by ear. Boom lists a maximum takeoff weight fractionally lighter than the lightest 737 MAX. The 737 has 238kn of thrust. Four F414 engines has 231kn of thrust without using afterburner. Boom has stated they will not need aft...
Jump to postSo the USS United States remains the fastest big ship of all time It would seem so. The Enterprise (CVN-65) would likely remain the fastest heavy carrier of all time, although she'd only have been a knot or so faster than her World War Two forebear, assuming CV-6 had clean bottom and the seas were ...
Jump to postIt also should be noted that while 30 knots isn’t that fast compared to airborne assets, it is still quite quick, and while carrier are big, the ocean is much bigger. Let’s say a Satellite spots a carrier. How long will it be before any ordinance can actually make it to the target? 30 minutes? A hou...
Jump to postHaving an office at an airport that sees F-18 takeoffs, I can say safely that engine is not quiet enough to be even considered. They make 737-200 and 737-300 that fly out of here sound whisper quiet in comparison! They are using afterburner on takeoff which more than doubles the loudness by ear. Bo...
Jump to postThe problem with a route like JFK-LAX is there is a ton of Y demand on the route too. A small premium only airline’s network would be too small to attract and fill a J only or even premium heavy A220 multiple times daily at profitable fares with all the competition, and an airline with a large netw...
Jump to postAlaska deviates some on their seating configurations for 737s versus the three other legacy carriers. I think the AS 738/9s have a row less in F but with similar overall seat counts (slightly more or less) versus DL, AA, and UA. Not sure of United's intended configuration for the -10, but Delta is ...
Jump to postI thought it was only the e2-190 and 195 that didn't meet scope? There is a scope clause limit for regional jets of 39 t MTOW. The E-175 has a MTOW little less than 39 t; the E 175 E2 has around 45 t MTOW. This is the reason, we have today seen the order for the E 175 and till now an empty order bo...
Jump to postWhy did the Italian Air Force order the F-35B? do they really need a STOVL jet? the Navy, I understand. The only mention I can find of it is that the Air Force is using the A to replace the Tornado, and the B to replace the AMX , which is used for CAS. Perhaps they expect to employ some sort of FAR...
Jump to postNo. Can you explain this? I'm not asking what you think is fair. You already said that, and were clear. Given the choice of more jobs, more profit, why do you say "no"? And do you understand that most would say yes? Well unless there is a chance of subsequent unit costs coming down for th...
Jump to postSorry if this has already been discusses, but if so I couldn’t find it. Does anyone know the rationale for the USAF choosing the PW4000 to power the KC-46 over the General Electric CF6-80. The USAF already operated the CF6 on many airframes such as VC-25, KC-10, and C-5M, so there would be at least...
Jump to postActions speak louder than words. Why do people love the F-16 or A-10? Because their stats are better than the F-35? Or because they've already seen it in action and know what it can do? No decisions are fully rational. Sometimes you need a little wow factor to get your point across. Maybe "com...
Jump to postBased on the numbers upthread, 6500 nm with that many seats blocked off appears doable every day, but 7000 nm is probably too far. At the moment I can't think of any routes where it would make sense, though. UA's routes where the hard product is most critical are TATL. Playing around on GC map the ...
Jump to postFor routes of 6000nm, little to no seats needs to be blocked if configured in current UA configuration. As aforementioned, 35t payload will be available, and that configuration only need about 315 pax to be taken care of. If not stuffed with excessive luggage (though probably will), the plane requi...
Jump to postWhy would they only be in west Germany? Basing nuclear weapons of any source in former east Germany would be in violation of the two-plus-four agreement (the one that defined the conditions for the reunification of Germany).* Further, currently the Tornado only carries unguided B-61-3/4. Whichever ...
Jump to postA 78X doesn’t cost much more to operate than its smaller siblings correct? I wonder if, until the 788 and 789 get their Polaris and Premium plus cabins installed, there are premium routes where the Polaris hard product and W cabin bump up RASM enough to make it worth flying a 78x with those cabins ...
Jump to postDeterrence is required and stealth is a powerful measure of this. Nothing deters warmongers like the the threat of their strategic assets and even personal safety put in harms way. The only russian assets threatened by the nuclear-sharing bombs are in Kaliningrad. And even that is just barely withi...

Well, it certainly does not have the output power of a Growler when it comes to jamming and ...
Jump to postLAS and MCO make a lot of sense. As well as business traffic and VFR, there are vacation possibilities both ways. Israelis want their holidays in reliably secure locations and the USA ticks those boxes. It's great to see LY moving outside of its prior niche of trunk routes and developing new market...
Jump to postLet me preface that I absolutely do not in any way expect this to happen. This is pure speculation. We know BA likes their high J 744s, especially on the LHR-JFK route. Allegedly one challenge with the A380 is that it can’t fit at BAs JFK terminal. Does a 748? Does a 748 offer any meaningful RASM ad...
Jump to postYes, but to start a New route that in 1-2 years there is a train service (if everything goes according to schedule) I don't think the route will survive after the train service starts, especially since LY flies TLV MIA flight 3 times a week and adding a 4th flight in November 2019. Why in the world...

Jump to postIs there intelligent speculation as to the required runway for the 777X? As long as the -9 is I feel like it's going to need more runway than the 77W. The reason I ask this in this thread is because it could restrict the possible base airports of the private owners of the 777X BBJ to major internat...
Jump to postIt actually wasn't that stealthy by todays standards. It also had poor situational awareness. Todays radar would pick up an F-117 quite some distance away. Stealth design was improving very rapidly as computer software improved in the 90's. So when its main strength was stealth it quickly became ou...
Jump to postThe AA narrowbody order by Arpey pre-bankruptcy was the first time AA ordered Airbus narrowbody. It was necessitated by the need to basically replace the entire narrowbody fleet and Boeing being unable to fulfill the need.

Jump to postBut why are they all called a 7xx? Why 7? I believe every Boeing passenger plane historically has a 7 somewhere in it's model number going back to the 247, 377, etc. so 7 was a requirement in naming the new jet transport. Was it a combination of luck and/or pure marketing genius to designate it the...
Jump to postAs for showers and such, several people have stated that its possible on A350s and 77s. So then, why has no one done it? EK is rolling out great new 77 products, so why not that as well?

Jump to postThe pmUA 77Es that have Polaris but not W are probably the closest equivalent to the 787s. They seat 292, which is 15% more than the 789s. According to the fleet site, none of these aircraft exist anymore. They’re still shown on the UA website (whereas the W configuration isn’t posted yet), but whe...
Jump to postI'm confused by some of the reasoning here. 1) Lower acquisition cost - maybe, or maybe not if you consider the costs of cancelling the order 3) Less capacity for better yields - sometimes that's what it means - sometimes it just means lost chances of flying customers and UA has a significant share...
Jump to postI see no reason why the 787-9 can't replace the 772's at UA. And I'd be willing to bet that Boeing would take care of any A350 penalties for a 787 and MOM order from UA. There have been no new Airbus deliveries since the merger and United really loves their 737 and 787. Meanwhile AA is about a 50/5...

Jump to postThanks for all that info. What about their specific payloads? Can the F-35 carry the same A2A armaments that the F-22 would be carrying? Without sacrificing stealth capabilities that is. I think we've already addressed that we can hang things on both aircraft's wings to match (somewhat match) the F...
