While certainly a great success, the 767 was probably too small a widebody to continue holding its own in the new century. Fragmentation at the lower end of it's market space meant aircraft in the 738/321 size could take over many of the routes, while at the higher end the A330 and eventually the 78...Jump to post

When I worked for a certain national carrier in SIN, their per diem policy was paid by regions, there was China/Asia, North America, Europe, Africa and India.

Personally, I notice. A 12-hour flight in the A350 leaves me noticeably less dehydrated and "spent" than a 9-hour flight in the A330.
The bunk in the A350 might help with this as well.
You can see in these cross-sections how the cargo space is much "taller" than the crown
Aircraft are typically weight limited anyway. Extra room to stow stuff doesn't do any good if you're maxed out on weight. In reality the floor to ceiling ratio is a lot closer to the lower drawing. The floor is located near the center of the tube to maximize floor space for more seats. There really ...Jump to post
“silent rooms” are necessary when you check in at 6am after a red eye flight and check out at 6pm for the next duty day (or duty night) of flying. Nothing is more annoying that getting housekeeping knocking on the door at 9am after you’ve finally gotten to sleep by 7am. I was honestly surprised dur...Jump to post

I wonder why the new carbon fiber airplanes are not certified to go up to 52,000 feet like some of the private jets? Is it really that much more difficult to go 6-7000 ft higher? It's not a big issue structurally or aerodynamically. We could theoretically cruise higher than the service ceiling, eve...Jump to post

Pilots don't arbitrarily say they won't fly the aircraft if the auto pilot is inop. They refer to the MEL and read the restrictions and that's usually after the dispatcher is involved and is fully aware of the restrictions. If the MEL says it is acceptable fly with restrictions like number of fligh...Jump to post
Good question! Not sure where you are located, but I can't think of many off the top of my head in the US.

Connect to the free WiFi and you can stream t...Jump to post
As I understand it, the weight penalty has decreased. A composite fuselage is lighter for the same strength. Also, it is less susceptible to corrosion, which is why the 787 and A350 can be pressurised to a lower cabin altitude (higher pressure and humidity).Jump to post
Pretty similar for us as previous posts. Most hotels are pretty nice, and some are fantastic. Hotels all have a gym, free wifi for crew, silent rooms.

777-9 further stretch? Very possible. Boeing has already proposed a 777-10. It would be a 3.3 meter stretch to a total length of 80m, meaning 40 more seats if you use the space for economy. I think this would make the available floor area more than the 744's. Trijet? Extremely unlikely unless someth...Jump to post
What about the passenger area? How much smaller is the B777-300ER/B777-9 compare to the B747-400? 777-300ER has smaller passenger count than 747-400 in normal, 3 - class configuration. 777-9 will be roughly the same as 747-400. It's pretty much a direct replacement of that model. Of course, passeng...Jump to post
Do away with engine bleed air entirely, like a 787. Bleed air is wasteful no matter what Airbus may say. All electric is the only way to go. Airbus didn't go all electric on the A350, indicating that with today's tech going all electric is by no means the obviously more efficient solution. As chimb...Jump to post
Out of interest can anyone describe the Airbus way of hand flying at a cruise level.

At major airports, external power is typically provided at the stand. However in some cases due to the cost it may be more economical to use the APU. At many major airports, APU usage is limited by regulation, so of course they have to provide external power. Even with external power, you need the A...Jump to post
The air to have high enough pressure and temperature to actually power the air cycle machines in the packs. My guess is you wouldn't get what you need from the low-pressure compressor (fan).

BTW, I just love the A400. Just a sweet thing to look at. Yes, the A400 is a sweet bird. I bet the Italians had something to do with it. They have such a great sense of style.

Another interesting question is why there is an inconsistency on when the flaps are retracted. Some pilots retract them immediately after leaving the runway while others (within the same airline) taxi with full flaps almost all the way to the gate. Shouldn't there be a checklist saying something li...Jump to post
I hate the toilet on the 1st generation A330. It is not the fear of getting sucked, but just the really loud noise that somehow freaks me out. Does the newer built A330 has a better sounding toilet? A vacuum toilet makes a sucking sound. I don't think designers design with flushing sounds in mind...Jump to post
Either way they'd need a type rating on the X. It's probably a full course from the I. It's not "retraining". It's training. You're not having to relearn stuff. You're learning new stuff. And if you already have jet experience, it does help. If they are separate ratings, which I'm guessing...Jump to post
I would also say in some airports with longer taxi time it will save enough fuel to make it reasonable to retract the flaps. Gee, I like your screen-name!

You can get a lot of range just by severely limiting payload. Even an A330 has a fuel capacity of around 109 tons, meaning that on full tanks it can fly around 17 hours. Part of the reason is A330 shares the same fuselage as A340, hence the more-than-necessary fuel volume. Had it been designed as a...Jump to post
Didn't Thai and Singapore Air once do something like this with A340s? Removed seats and added tanks so they could fly from LAX or EWR non-stop to BKK and SIN? Don't think so.

No FBW doesn't mean it has no augmentation. The controls would still have artificial feel and be balanced for the aircraft. I don't think the CoG is high, even when loaded.

The lock mechanism is just a mechanical hasp. About as simple as you can make the thing, so there's not much that can malfunction.

In general, since it is a one crew aircraft, you may not both log hours. Only the pilot flying, which in a single crew aircraft would be the PIC, may log hours. There are exceptions.

T0 and 24 are customer codes. AFAIK they don't tell you about the spec per se. Given that Continental became United, the customer code changed.

How do pilots physically handle the throttles in an assumed temperature takeoff?
