ET Flying 763's On YYZ-ADD

Thu Feb 21, 2013 2:37 am

I noticed that since the 787's have been grounded ET has been flying 763's on the YYZ-ADD nonstop. These 763 must take a major weight restriction on a 7200 mi flight. Does anyone have any ideas how many seats ET is blocking off to make this work?

ET is flying the 763 on the IAD-ADD sector as well. I guess it's low season across the atlantic.

It makes a stop in FCO en route to YYZ and IAD

Yes but the YYZ (and IAD) - ADD return is non-stop, even with the 763.

AC flew the B767-300ER from YYZ-NRT, 5574 nm, against winter north Pacific winds. The capacity was originally capped at 180 passengers, then all load restrictions were canceled, as most of the time the aircraft could do it. If I recall, 2 or 3 flights had to stop at YVR, during the whole season. Baggage was carried, but cargo was routed through YVR.

The return NRT-YYZ was never an issue.

YYZ-ADD is 6217 nm. I am going to guess that with prevailing westerly winds, likely the aircraft can fly the route unrestricted.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

Like longhauler said, with a good tailwind, it is more than doable with a full load of passengers. No cargo though.

Page 51, as ET has GE powered 763's i believe.

us Air Traffic Controllers have a good record, we haven't left one up there yet !!

No ET has PW on their 767's

Doesn't change much anyways in terms of payload vs range.

No, I fly both PW and GE equipped B767-300ERs, and they are within spitting distance of each other with regard to performance.

Likely the biggest gain I see with ETs B767-300ERs would be the winglets a few have.

It's still roughly 500 nm further than TLV-MIA which LY operated nonstop with the 762ER. Can't recall many longer 767 nonstops than that, especially westbound against headwinds. It's also 164 nm further than YYZ-NRT.

Look at it another way, and this is a rough explanation.

And some assumed parameters:

Cruising at 470 knots TAS
300 nm to climb to cruising altitude, then descend to destination.
50 knot westerly winds at cruise. (likely more than that, but we'll go with a worst case scenario)

YYZ-NRT is 5574 nm, subtract 300 miles and you are 5274 nm at cruise. At 470 knots TAS - 50 knot headwind is a 420 knot ground speed. Time in cruise is 12:33. This was achieved by AC, in a regular B767-300ER in all but ~3 times.

YYZ-ADD is 6217 nm, subtract 300 miles and you are 5917 nm in cruise. At 470 knots TAS + 50 knot tailwind, is a 520 knot ground speed. Time in cruise is 11:22.

So YYZ-ADD is roughly an hour quicker than YYZ-NRT, of which the B767-300ER was capable. That is why I think if AC was able to fly YYZ-NRT, then ET should have no problem flying YYZ-ADD.
