What is the maximum range WITHOUT the aux tanks? Do you know which airline use this tanks?

[maukro_1990 38]

Hello everybody!

 

Is there someone who can tell me the maximum range of the PMDG 777-200LR WITHOUT installed aux tanks? I´m asking becouse i installed these tanks in my PMDG T7, but i really can´t find a route to use them. Is not the range of this aircraft more that enough without these extra-tanks?

 

Do you use them?  What about the "real" 777-200LR operators: Are these aux tanks installed in Delta -200LR´s? 

 

I hope that you can answer my questions!

Rumors are that air canada is now fitting their LR with the AUX tanks, speculations are that they will offer a non stop flight from CYYZ to YSSY instead of going to CYVR first. But again, these are rumors.

Okay, thank you! But do you now how far i could fly without any AUX tank?

For the Passenger at maximum takeoff weight somewhere over 9000nm. For the freight at Max takeoff weight about 5000nm

I have already flown my Emirates 777 from OMDB to KLAX. Emirates doesn't use AUX tanks, but as far  as I am aware this is the longest flight done in the 777 (300ER IRL).

Thanks for your reply. Are you sure that Emirates don´t use these AUX tanks? OMDB - KLAX?! Wow... This is an 16 hours flight. This means that the range of the -200LR without extra tanks is more than enough. 

 

Why is there an option to add these AUS tanks? 

[tcas_climb 45]

The record to longest flight by an airliner is held by the LR done by Boeing during a test from asia to England traveling east, the long way around, somewhere over 22 hours.

 

I read somewhere that Emirates bought the LR operate non stop from Dubai to LA, but they use the 300ER instead which has a slightly shorter range.

Longest flight according to wiki:

 

Qantas: Sydney - Dallas 747-400er 7400 nM

(Dallas-Sydney has 1 stopover)

Delta: Johannesburg - Atlanta 777-200lr 7300nM

Emirates: Dubai-Los Angeles A380 7200 nM

 

You will get to a point where passengers will rather do a stop then fly for 20+ hours straight.

Combined with the fact that aux tanks takes up space, weight and burns more fuel to carry its extra fuel, aux tanks are not popular.

 

The 777-200LR does its job best without them. But in the aviation world you never know

To answere your other question. You can setup a specific aircraft with or without aux tanks in the operation center.

Max ranges according to Boeing:

 

* 777-200 = 5240 nm (31,000 U.S. gal)

* 777-200ER = 7725 nm (45,220 U.S. gal)

* 777-200LR = 9395 nm (Three optional fuel tanks - 53,515 U.S. gal)

Okay guys!

 

I just found the Boeing 777 performance summary, where you can find the datas for our -200LR (you have to scroll down in this document):  http://www.boeing.com/assets/pdf/commercial/startup/pdf/777_perf.pdf

 

These are the following ranges  for the different Boeing 777-200LR configurations, with MTOW and full passenger payload : 

 

                                             

                                                                                                                  Fuel capacity                             Design range

Boeing 777-200LR "Basic":                                                           181,280L (47,890 u.s.gal)           8,295nmi (15,360km)

Boeing 777-200LR "Maximum" (GE90-115BL):                           181,280L (47,890 u.s.gal)           8,665nmi (16,045km)

Boeing 777-200LR "Maximum with three AUX TANKS":           202,570L (52,515 u.s.gal)           9,395nmi (17,395km)

 

Now we all know that the maximum range of our PMDG 777-200LR (which has the GE90-110) is 8,295nmi - 8,665nmi without any optional fuel tank. Wow! I can´t really find a reason to add these aux tanks^^.

No airline currently uses the aux tanks. Boeing offers the option and I think a few originally had it but had them taken out after they proved to be less useful than more load carrying capacity.

Tank you! Ok, i see. Maybe there will be a non stop flight from London to Australia in the future^^. Than these aux tanks will be useful, i think. Otherwise the range 15 - 16000km without aux tanks is more than enough, right?! ^^
