Norwegian today announced a loss of US$180 million for Q4, double the loss expected by the analysts. For full year 2017 the loss was US$ 138 million.

Interestingly enough, when facing head winds the optimum true airspeed for max range/lowest fuel consumption per distance does in fact increase. And the reverse when facing tail wind. Say max range cruise speed is mach 0,78 in still air. When facing severe head wind the maximum range true airspeed g...Jump to post
The finnished carbon/resin composite would weight something around 1,4 kg/mm/sqmtr. So a 1,1 kg/sqmtr would be about 0,8mm thick. But you are probably correct that this is way too much for one single unidirectional layer. But a 0,1mm thick layer is only about 100 grams/sqmtr or less of carbon, that ...Jump to post
Lighter wing (1 less carbon layer on both upper and bottom side of the wing) Any idea how much weight saving that constitutes? same for the new doorframing. Napkin calculation... Carbon fiber, 300 grams/sqmtr, resin for this layer is about 250 grams, so, 550 grams/sqmtr. Double this for both top an...Jump to post

In the long run, what's worse for Boeing is that the 779's advantage is ephemeral in that it relies, to great extent, on better engines. I expect Boeing to reengine the 787 sooner than currently imagined - perhaps as early as 2025 with Ultrafan - and I expect Airbus to match that move. When that ha...Jump to post
I didnt mean Qatar in any way is/was reasonable, because I dont think they have been that. But when we are talking about what frames should actually end up not beeing delivered, objectively it is more reasonable to not deliver not yet built frames than to not deliver already built and equipped frames.Jump to post
That's why we have seen activity on MSN 63 recently. Aircraft came suddenly out of storage. And so QR doesn't need to increase its order book to re-take the 4 canceled aircraft. Just cancel 4 aircraft further down the road. Sounds reasonable. I notice MSN 161, 163 and 172 for Quatar have still not ...Jump to post
Indeed, the vertical height seems to be slightly less than the fan diameter, and that is what, 1,9 mtr, or only about 5,5 ft. If we add the small winglet on the underside we reach maybe 8-9 ft. The fan diameter of the GP7000 is much bigger than 1.9m. It is 3.16m (10.4 ft; 124 in). In my view the wi...Jump to post
nope, I still get a hight slightly less than the fan diameter, even in the latest picture. And the downward pointing one is just tiny. I am disappointed. I can not belive this is the best Airbus could do. I want an at least 5mtr/15ft high skarklet!
Wow, ten times, daily.....Jump to post
Finally! I have never understood why Airbus have been so slow in implementing large winglets on the A380. This should have been done years ago. But better late than never. It is almost like I can have some faith in this combined effort, slightly better RR engines, around ten percent more passengers ...Jump to post
Prevailing winds, at altitude, in Norway are of the South/Southwest? Gemuser To be honest, I dont know about at altitude. But at ground level the winds are definitely coming from south west/west more than any other direction. Especially at autumn/winter time we have a lot of south west/westerly win...Jump to post
Hmm, I dont know what to say about that route. I see it skims the cost of norway. In that area the prevailing winds will definitely be headwinds. I live there so I know. I would go as far as to say that the prevailing winds all the way from the kink on the northern siberian coast and all the way to ...Jump to post
[quote="SteinarN ] How many nm will the ground distance be eastbound? And what is the required average tailwind so as to make the air distance shorter than the westbound route at about 10.000nm?[/quote] Eastbound it is ~9800nm. Assuming a average positive tail wind of ~ 20k the ESAD would be 9...Jump to post
So, we see that if about 10.000nm air range is required going west against the prevailing winds then 300 passengers is clearly out of the question for either plane. Even 200 passengers seems to be a stretch but if any plane can do that is must be the B778. But the route will not be flown westbound,...Jump to post
Acording to Leeham; The A359ULR can trade passengers for fuel all the way down to 75 passengers. Then the tanks are full and the range is 10.400nm. The B778 can trade passengers for fuel all the way down to 160 passengers. The tanks are then full and the range is the same as A359ULR, namely 10.400nm...Jump to post
To make some simple math. Boeing expects to produce 140 787's a year for a total profit (which I assumes is about the same as free cash flow and not booked profit) of 70 million times 140 copies a year for a grand total of 9.8B US$. This for one single wide body program. This seems totally in break ...Jump to post
That also relates to the relevant firing rate at the time they were loaded from what I see. It also looks like the firing rate has increased again but difficult to tell. Pre-assembly is clearly running at 6 per month now. Spirit AeroSystems delivered 19 A350 ship sets in Q4 2016. https://imagr.eu/u...Jump to post
And how are you going to do the pressurization? It is easy to pressurize a tube but a more flat/oval structure needs much more strenghtening to sustain any pressurization, which adds a lot of weight.Jump to post
They could always "fudge it" to 50 by including "delivery" of the first 350-1000 to their flight test department :) Yes, I suppose they could! Next thing we see is Boeing moving their 777 "blank rounds" through the FAL to a blank customer and then counting those as suc...Jump to post
It looks a bit bad tempered from that angle. Maybe not happy about having to wait for its engines.
What would happen if say one Airline offered two, maybe three departures daily on a super efficient 750-800 seat SuperNeo between LHR and JKF at 75% of the price any other airline could fly semi profitably for? The other airlines flying other types of aircraft would reduce their prices to the new l...Jump to post
I was thinking the same thing - however we must keep an open mind here. If there was any sort of hydraulic failure, it's more than possible that the slats on one wing had retracted, asymmetrically. Lucking she's a T-tail or there almost certainly would have been some control loss on the hstab. You'...Jump to post
I agree that if Airbus dont do anything then the program will be stone dead soon. But that will be incrediby sad for several reasons. First, from a passenger perspective, the A380 is effectively the ONLY new aircraft left with somewhat acceptable seat with in coach and it is also the most silent air...Jump to post

Using a modern inline four automobile engine in an airplane is possible and already done, it's called a Thielert (now Continental), the base engine is a Mercedes.

Zeke There is a lot of problems with what you have posted regarding versions and range of this aircraft.

In short, the IRU1 failed in the pitch channel, this faulty data was displayed to the left seat pilot via the the primary flight display showing a rapidly increasing pitch, up to 30 degrees, while the aircraft actually was level and perfectly stable.

The problem with the 777X is not how its projected performance compares today against todays aircraft with todays engines.

Regarding Qatar, I will hazard a guess. Qatar is simply out of money and are not able to pay for their planes and/or cabin equipment.

Does anyone know how many hours storage capacity the cockpit voice recorder have in this plane?
The plane took off about 4,5 hours before it crashed, I wonder if the start of the flight might be erased from the cockpit voice recorder due to not enough storage capacity?
Is the A350 allowed to fly with only one winglet, like the A330, or no (like I believe the 737 with blended winglets?)? It is most certainly allowed to fly long enough so that it can land. But I doubt it is allowed to take off with one missing, altough i am sure the aircraft would have no problem b...Jump to post

The first delivery as soon as in 9 months. Does this mean that Boeing do have some open slots for the B787 at the current production rate of 12/month as early as next year?
