Lightsaber, Thank you very much for the great analysis of the evolution of a venerable 737 aircraft. What I did not consider was the fact that the 737 evolved in stages as already certified and proven aircraft in volume production with amortized initial engineering costs. I now see that, if the CR92...Jump to post
Aircraft has a sales shelf life. New technology comes out and the base concept that can usually be improved about a half generation of tech. But at some time a significant redesign is required (rewing and re-engine). But unless subsystems are replaced, maintenance and NVH (noise, vibration harshnes...Jump to post
Perhaps the same reasoning not to put a captain "Over" and a co-pilot named "Roger" in the same cockpit should be at play.
There are just too many flights named "Delta" already at Atlanta, and now a taxiway whose phonetic alphabet is "Delta"?

I can see some smart geek to come up with a wireless-recharging device for this plane, so that it can "harvest" some power by flying parallel to a high tension power lines. Steady hands are a must.Jump to post
If the aircraft had to fly through a known icing condition, and the exposed rudder cables are encased in layers of ice....
It certainly could have caused some safety issues, methinks.
There is a plane for every airline and a plane for every application. The A380 has done wonders for Emirates, same as the 777. The 747 has done wonders for British Airways. The phrase, "for every application" has a big implied assumption. That is "for the socioeconomic condition of t...Jump to post
The material to make a faraday cage must be electrical conductive. CFRP is an electrical isolator. Perhaps you crack a textbook.

To stop the armchair pilots and mechanics at the root: it was neither pilots', operator's or aircraft's fault for this event. Be patient for once and wait for official statements. Trust me, I know.

I flew back from FRA on Lufthansa 422 this past Sunday (12/29). The 744 flight was almost full.

On the bright side, the newly re-organized Alitalia may become the first airline to land at newly opened BER.
What the Italian government needs may be the U.S. Chapter 11 style bankruptcy law that can truly re-start the corporation with a clean slate.
I like to think A321LR will facilitate reducing a [ spoke #1 -> Hub #1 -> Hub #2 -> Spoke #2 ] itinerary to a [ spoke #1 -> Hub #2 -> Spoke #2 ] or a [ spoke #1 -> Hub #1 -> Spoke #2 ] rather than "hub busting".

The A380 didn't have section mismatches, that was the 787. And that was with three design teams working on a single digital model. The A380 wiring looms were problematic because the two design teams used different modelling principles. Actually, if I recall correctly, the mismatch was due to the fa...Jump to post
Wouldn't a decrease in the value of the lira result in an increase of travelers to Turkey since everything would be relatively cheaper to USD and other hard currency holders ? Which simply means that each inbound traveler to Turkey spend less hard currency in the country for a given level/quantitie...Jump to post
Nominal lira costs will surely go up, but TK won't have a difficult time paying for it because 85% of their revenue is in foreign currencies (USD, EUR, GBP). 15% of their revenues is in Turkish Lira. Jet fuel prices will go up in terms of Turkish Lira but dollar wise jet fuel prices will stay the s...Jump to post
Again you miss the point. TK takes in more foreign currency than it pays out. It can pay LHR charges with the GBP it earns, aircraft leases with USD and have foreign currency left over. Its cost is more in Lira's so, the weaker it gets the excess foreign currency it buys even more off. Hence why TK...Jump to post

The new Y-shaped terminal concourse looks like a great improvement.
There may be a bottle-neck trying to get to the East side runway from the West side gate, and vice versa.
It should not be a problem provided they have a de-icing station on each side of the airport.
Based on google earth imagery from 11 months ago, the south runway (the new one) isn't used. There are X's painted on it. You are quite right. I stand corrected. I had thought the new runway 07R/25L was in a normal day-to-day use by now : Take off at Berlin-Schönefeld Airpot (SXF) - on new Runway 0...Jump to post
Forgive me if I am mistaken, but I thought BER is just an expansion of the existing SXF airport with a new set of runway/taxiways and a new large terminal building that is built based on a new theory of anti-gravity. I thought the new runway is already in use as a part of SXF... So, effectively, &qu...Jump to post

I assume aircraft take-off/landing cycles as well as the flight hours figure in the residual as well. A 737 that belongs to a 70-year old lady who uses the aircraft only on her weekend jaunts to/from the Cayman Islands may retain its value better. Long-haul carrier's aircraft may have much fewer cyc...Jump to post
One would think that the automatic monitoring system should be able to detect the combination of "wildly different air speed indications" plus the "pitot heat off setting" and can come up with a more intelligent warning message.Jump to post

I see a potential technical issue in this BFR scheme.
I do not think the current-day air-sickness bags would work well in a micro-gravity environment.
(Gravity is your friend in this case.)
Each seat should be equipped with an equivalent of a dry/wet vacuum cleaner.
I humbly propose that they test the effectiveness of the fire suppression / smoke abatement system for the terminal by actually setting the building on fire. If it works, we know it works, and, if it doesn't work, well, it doesn't work, and we should let the fire to consume it completely. Either way...Jump to post
Thanks for the great points.
If a potential customer does not need a rough field performance nor high-threat operational capability, a simpler cargo jet equipped with a pair of ubiquitous CF6 engines may be easier to maintain and support, with a hot-and-high performance as a bonus.
I get it now.
There seems to be an undeclared "limit the Korean influence" policy in China right now as well as a diplomatic wrangling between South Korea and Japan causing South Korea's industrial output (auto and shipbuilding) and tourism to actually decline.

Alitalia deserves stiff penalties.
However, if "all roads lead to Rome", the converse is also true.
