I cannot seem to obtain consistent figures for max range of a 767-300. I am getting between 5895nm to 7080nm. Where is the true figure? If there is a Boeing Engineer or a 763 rated pilot or FO who can confirm the range, please do so. Also, what is the ETOPS minutes for a RR 763 (BA, QF)? I've got conflicting reports on that too.

From Boeing:

For 0.8M cruise, at FL350, 390 and 430, ATA Domestic reserves, Standard day, Take off Weights at 2000lbs below taxi weights... Figures are correct as of... yes, 1989 ! *sorry, can't find anything else*

B767-300 on Max range (full fuel zero payload) is 5050NM, 4000NM on max pax and baggage only.

B767-300ER, the figures are 7400NM and 6100NM.

I suggest you go and look at the aircraft performance charts off Boeing's site.

It depends on an enormus amount of factors, mostly involving the airport where it took off from, the fuel carried, the engines, etc. I'm a pilot, but not a 767 one. But, I do have the performance charts for the various 767 types available to me.

B767-300ER (Standard day, domestic reserves, 0.80 mach cruise, ballpark figures for an average aircraft, OEW of 196,000lbs):

Max range with 261 passengers and baggage (takeoff weight of 406,000lbs): 6150nm

Range with no payload and full fuel (takeoff weight of 360,000lbs): 7400nm

Range with full fuel (~145,000lbs) and max allowable payload after that (~65,000lbs): 6400nm

Range with max payload (~92,000lbs) and max allowable fuel after that (~119,000lbs): 4000nm

------------------------------

Just incase you're curious, for the same conditions (max takeoff/landing weight, standard day, sea level airport with dry runways), here are the takeoff and landing distances for an RB211-524H equipped aircraft:

Takeoff: 8900ft (flaps 15)
Landing: 5200ft (flaps 30)

------------------------------

Let me know if there are any other specs you would like.

Wilax,

British Airways have full 180 minute ETOPS on their RR 763s, as do Britannia, Air 2000 and MyTravel in the UK (though the latter 3 are all obviously GE-engined).

Maximum range varies from aircraft to aircraft based on OEW and fuel burn (which is always slightly different for each bird in the fleet). In terms of N.A.M (nautical air mile) range I would say we cannot get 6,400nm air range out of our fuly-loaded 763 (315 pax + bags + up to 9,000kg cargo) and depart with legal (JAR) reserves even with as much fuel as possible (takeoff @ MTOW).

5,500nm air distance (IMO) would just about be max range fully loaded. That just about covers our MAN / LGW to CUN flights, which run very close to MTOW on some days.

Range with fuel fuel and max payload after that / full fuel and no payload are meaningless figures as they are of no use to anyone in the real world.



I used to love the smell of Jet-A in the morning...
