Confusion about 777 Range

Recommended Posts

Hello everyone,

 

I haven't been on the forum in a while, the 777 is looking awesome! I'm confused about the range of the 777 though... For instance, I live here in Houston and Emirates flys a 777-300ER from Houston to Dubai nonstop. The maximum range for a 777-300ER is 7,930 nmi. If you look on flightaware: http://flightaware.com/live/flight/UAE212 its a 8,300 nmi flight. So what am I missing here? Do some airlines mod their 777's with extra fuel space for extremely long range flights or something? It's clearly out of the 777's range.  http://en.wikipedia.org/wiki/Boeing_777

I see 7190 nm on that flightaware link, not 8000+...

 

Yeah- I think the OP got confused between miles and nautical miles.

Looks like it since 7190 NM is 8269 SM. Also keep in mind that with a full pax load the tanks aren't full, so for extra wiggle room you can reduce pax/cargo for more fuel.

OP is confused between nautical miles and statue miles. The distance and range are quoted using diffrent units.

 

1 nm = 1.15 sm

 

Wikipedia quotes the range of the 300ER at 7,930 NM. Therefore, that equals 9119.5 SM. The flight looks to be around 8200 SM so it is well within range for the 777-300ER.

Maybe a flightaware glitch?

Mate, once again it's SM. Boeing measures the range in NM on the technical specifications.

True, but on the post you quoted, it says "Flown: 11,518 sm" which is 10009 NM, which is well above the -300ER's quoted range on the boeing website.(7,825 nautical miles)

Ahh okay. That's probably a fault on flight aware's site then!

Yeah flightaware can act funny sometimes. One time it claimed a flight from london to houston was 20 minutes.
