Wäre es möglich diese Thematik aufzuteilen? Mein ursprüngliches Thema war der Check-in mit "Li-Ion Batterien im Reisegepäck". Die Probleme der 787verfolge ich zwar auch sehr interessiert, sollten aber m.E. vom Ursprungsthema abgetrennt werden. "Salamat po"
Vollkommen richtig, deswegen zum Thema Dreamliner, bitte hier ---> "Dreamliner"-Untersuchungen laufen - 787-Batterieproblem im Fokus weiter posten.
Die ICAO hat einen Stop fuer shipments von Li-ion Batterien auf allen Passagierflugzeugen verhaengt. Der Ausloeser war, dass 2 Boeing 787 "brennende Batterien" an Board hatten. Mittlerweile sind die Batterien also Gefahrengut wieder eingestuft und duerfen als solches nur auf besonderen Frachtmaschinen geflogen werden.
U.N. halts 787 battery shipments on passenger planes
ZitatAlles anzeigenThe United Nations' aviation watchdog said on Wednesday it is suspending a short-lived waiver that let airlines ship the batteries behind the grounding of Boeing Co.'s new Dreamliner planes as cargo on passenger planes.
The change to the International Civil Aviation Organization's safety standards is temporary, pending investigations into problems with the batteries, the Montreal-based agency said in a release.
The waiver, in force only since the beginning of this year, was intended to let airlines flying the Dreamliner to use passenger planes to ship the lithium-ion batteries "in special circumstances." Wednesday's change does not affect cargo planes.
The Federal Aviation Authority grounded all 50 Boeing Dreamliners in commercial service on Jan. 16 after a series of battery-related incidents, including a fire on board a parked 787 at Boston's Logan International Airport and an in-flight problem on another airplane in Japan.
The groundings have cost airlines tens of millions of dollars and have sparked growing concerns about the powerful but delicate backup energy systems.

Wie würdest Du (als Fachmann für Flugrecht) Dich verhalten?
Digitalkameras, Handys und Notebooks nutzen ja idR Li-ion Akkus.
Werden dort idR Ausnahmen für Kleingeräte gemacht? Wann zählt zb ein 17" Notebook nicht mehr als Kleingerät?

Meine Antwort ist ganz einfach: Weiss ich nicht! Denn ich habe mich in diese Materie noch nicht (und hoffe auch, dass ich mich da nicht reinarbeiten muss) befasst.
Ich sehe nur dass in der Vergangenheit bereits 2 B747 Freighter mit LIthium Batterien abgestuertzt sind und dass unsere Crews seit heute die Anweisung haben besonders Vorsichtig zu sein mit Li-ion Batteries und KEINE Spare-Batteries mitfuehren duerfen.
In einer Situation wie dieser, wo Li-Ion Batteries im taeglichen Leben nit wegzudenken sind, darf man auch nicht ueberreagiern und sie sofort komplett verbieten. man muss halt etwas vorsichtiger sein wie normal und die Befoerderung soweit es geht limitieren, ganz unterbinden kann man sie wahrscheinlich nicht.

Ferner gibt es ein noch gueltiges SAFO fuer Risks in Transporting Lithium Batteries in Cargo by Aircraft von 8. 10. 2010
Dort steht u.A.
ZitatAlles anzeigen: It is recommended that all air carriers institute additional procedures for safely
transporting lithium batteries by aircraft:
1) Request customers to identify bulk shipments of currently excepted lithium batteries by information
on airway bills and other documents provided by shippers offering shipments of lithium batteries.
2) Where feasible and appropriate, stow bulk shipments of lithium batteries in Class C cargo
compartments or in locations where alternative fire suppression is available.
3) Evaluate the training, stowage, and communication protocols in your operation with respect to the
transportation of lithium batteries in the event of an unrelated fire.
4) Pay special attention to ensuring careful handling and compliance with existing regulations covering
the air transportation of Class 9 hazardous materials, including lithium batteries.
These recommendations are limited to lithium batteries transported in the cargo hold of an aircraft (including
cargo holds that are not distinct from the flight deck), and do not apply to lithium batteries carried onboard
by passengers and crewmembers, or otherwise stowed in the passenger cabin of the aircraft. These
recommendations are not exclusive; we hope that carriers will use the information provided here and in our
Tech Center study, together with any other available information, to consider other reasonable measures they
believe appropriate to mitigate the risk of transporting lithium batteries by air.

ZitatAlles anzeigenSafety is a sensitive issue that gets much media and legal attention, especially with Li-ion batteries. Any energy storage device carries a risk, and in the 1800s steam engines exploded and people got hurt. Carrying highly flammable gasoline in cars was a hot topic in the early 1900s. Battery makers are obligated to meet safety requirements, but less reputable firms may cheat — it’s “buyers be beware!” Most OEMs use only Li-ion batteries that comply with one or several safety standards.
Lithium-ion has a high specific energy and even though safe, high usage by millions of consumers is bound to generate failures. In 2006, a one-in-200,000 breakdown triggered a recall of almost six million lithium-ion packs. Heat-related battery failures are taken very seriously, and manufacturers choose a conservative approach. Let’s examine this closer.
Sony, the maker of the lithium-ion cells in question, points out that on rare occasions microscopic metal particles may come into contact with other parts of the battery cell, leading to a short circuit within the cell. Battery manufacturers strive to minimize the presence of such particles; however, complex assembly techniques make the elimination of all metallic dust nearly impossible. Cells with ultra-thin separators of only 20–25µm are more susceptible to impurities than the older designs with lower Ah ratings. Whereas the 1,350mAh cell in the 18650 package could tolerate the nail penetration test, the high-density 2,400mAh becomes a bomb when performing the same test. New safety standards are more lifelike and the UL1642 Underwriters Laboratories (UL) test no longer mandates nail penetration for safety acceptance of lithium-based batteries.
Li-ion using conventional metal oxides is nearing its theoretical limit on specific energy. Rather than optimizing runtime, battery makers are improving manufacturing methods to enhance safety and increase the calendar life. The real problem lies in rare occasions when an electrical short develops inside the cell. In such a case, the external protection peripherals are ineffective to stop the thermal runaway, once in progress. The batteries recalled in 2006 passed the UL safety requirements — yet they failed in normal use.
Let’s examine the inner workings of the cell closer. A mild short will only cause elevated self-discharge and the heat buildup is minimal because the discharging power is very low. If, however, enough microscopic metallic particles converge on one spot, a sizable current begins to flow between the electrodes of the cell, and the spot heats up.
Uneven separators may also trigger cell failure. Poor conductivity due to dry area increases the resistance, which can generate local heat spots that weaken the integrity of the separator. Heat is always an enemy of the battery. When fully charged, elevated temperature causes a harmful reaction between the positive and negative electrodes and the electrolyte. As a small water leak in a faulty hydro dam can develop to a torrent and take a structure down, so also can heat buildup damage the insulation layer in a cell and cause an electrical short. The temperature can quickly reach 500°C (932°F), at which point the cell catches fire or explodes. This thermal runaway that occurs is known as “venting with flame.” “Rapid disassembly” is the preferred term by the battery industry.
If the battery gets very hot, immediately remove the device from proximity to flammable materials and bring it to a non-combustible surface. If at all possible, put a disintegrating laptop or cell phone outdoors and let it burn out. If the fire occurs in an airplane, FAA tells flight attendants not to use fire extinguishers but specify water or pop (soda). Water cools the adjacent material and prevents the fire from spreading. Many research laboratories and factories also use water to put out battery fires. Allow good ventilation while the battery burns itself out. Li-ion contains no lithium metal and does not react with water. A fire with batteries containing lithium metal requires a different extinguishing method.
During a thermal runaway, the high heat of the failing cell may propagate to the next cells, causing them to become thermally unstable also. A chain reaction can occur in which each cell disintegrates on its own timetable. A pack can thus be destroyed in a few seconds or over several hours as each cell is being consumed one by one. To increase safety, packs should include dividers to protect the failing cell from spreading to the neighboring one. (In the Tesla Roadster car, each cell is encased in its own metal compartment.) Figure shows a laptop that was damaged by a faulty Li-ion battery.

Na toll, alle Reserveakkus und Powerbanks ins Handgepäck, auch alle Akkulampen und Bohrschrauberakkus. Da wird schon was an Amperestunden zusammenkommen, zur Not kann man dann was zusammenschweißen, wenn was im Flugzeug kaputt gegangen ist.
