B757 international cruise speeds

[BoilerUP]

For those of you who are flying 757s to max range across the NAT to and from Europe, what altitudes & cruise mach do you normally fly for the crossing (especially westbound)?

Thanks...

We go to JFK-Germany right now. Normally anywhere from .78-.80.

Ususally faster westbound. :erm:

What's Mmo on the 75/76 anyway? Heard ATC ask a United the other day how fast he could go and he answered .89. Only thing we figured it could be was a 757 since he wasn't using a Heavy callsign.

Crossings on the tracks are flown at constant mach. Almost always (99.9%) flown at M.80 by 757's. Altitude depends on weight but generally mid+ 30's.

You are only required to use the "Heavy" designation with local and TRACON controllers not en route. However, the northeastern provinces of Canada use it. Where were you?

Depends on a lot of factors. Here at CAL we stretch the capability of the aircraft with ARN, HAM, OSL, BCN. I have taken off from some of these places maxed out on gas (76,900#) and had to put the CI at 0 just to show FOD over 9,000#. This results in a cruise of .77 in the mid to upper 30's, hopefully NATS gets you the FL you need or else you're pinched. Eastbound is no problem.

Agreed. We do destinations in Spain as well.

Normal NAT crossings are done at .78 or above for the 757/767. I have done 81 but we prefer to do 78/79.

I've done .83 back from DUB , fat on gas and 3 hours late.
