Boeing Winds
Can anyone give a heads up on a source for Boeing 85% Annual Winds - besides the obvious answer that is. Not an airline type I'm afraid so can only access the general public areas of Boeings web site.
Thanks in advance.
Thanks in advance.

There are various references to
"ISA conditions, 85% annual winds"
to do with A/C range
such as here Marquis Jets - BBJ Range
Afraid I'm not qualified to explain further.

tables
You want the tables don't you?
These days tend to be on a PC disk.
PM me if you want them and we'll have to figure a way.
Basically they give you a series of fixed pressures, departures and arrivals. Mines are at the 50% probability level and you convert them to the level of statistical significance you require with the aid of a small side table.
Thus you look up Lisbon- New York, say, choose the month of the year and the relevant press alt or alts and you have HW/TW, temp. If it says -35 then there is a 50% statistical probability that the winds will be BETTER than the quote. The side table gives you an interpolation. Bear in mind that to be 85% "sure" that the calculated value will be bettered that value will have to be more adverse than the 50% value.
SITA is your other source. To be honest, not being funny, I thought they were more available than they obviously are.
Happy to scan and post 'em but its a big, big document. Sure your ops dept don't have them on-disk, on-line, on paper?

head_girl,
I had a look at the SITA site but was not able to find any reference there. Are you able to give a URL? If not able to find it there would you be able to burn a CD if you have it on computer? I'm in Victoria (not too far in world terms from you). Whatever works for you but I wouldn't want to put you to great trouble and will reimburse for costs. My story is I've not long retired from a life (pilot) in the helicopter offshore business. I gather from your profile you are just getting started - in some ways I envy you - wouldn't mind doing it all again - it treated me well and I hope you have the same good fortune.
Blue Skies,
Brian

SITA URL I can't find as they appear to have changed their their site quite a bit.
To run Boeing PC Windtemp you need to contact:
Flight Operations Performance Software
P.O. Box 3707, MC: 20-88
Seattle, WA 98124-2207
Phone: (206) 662-7600
Fax: (206) 662-7612
I can sort something on a disk I'm sure.

Boeing migrated the information into a computer program.. You can approach them at the address given above, however they usually like people to own a couple of their aircraft and sign a massive liability disclaimer before they release any software...

PC WindTemp
INTRODUCTION
The Boeing PC Windtemp program provides global average and statistical winds and temperatures aloft over a 30 year period. These data are used primarily for comparative transport airplane performance and economic studies. The data may also be used for transport airplane route planning on an annual, seasonal, or monthly basis.
Note: Actual winds and temperatures at a specific location and time may differ appreciably from those computed by PC Windtemp. Therefore, data from PC Windtemp must not be used for flight planning, aircraft dispatch, airborne flight navigation, or any other type of actual flight operations.
PROGRAM FEATURES
A seasonal and monthly database with global coverage from 1000 millibars (364 feet pressure altitude) to 10 millibars (101,885 feet pressure altitude).
Annual data updates to the most recent 30 year period.
Airport codes and coordinates may be imported from a text file in a comma separated value (CSV) format
Calculates enroute wind and temperature for up to 50 airport pairs at a time.
Calculates enroute wind and temperature for simple great circle tracks or tracks with up to 250 waypoints, with or without altitude changes.
Calculates average enroute wind and temperature or any reliability (quantile) between 50% and 99%.
Months or seasons, reliabilities, altitudes, and speeds may be nested for input efficiency.
Formatted and text output reports are available.
Program subroutines (DLLs) can be called from other programs written with C++ or Visual Basic in order to incorporate Windtemp functionality in those programs.

mutt,
Do you think they would accept my boeing frequent flyer points? Come to think of it though I do own some boeing airframes 707, 737, F18 (the ADF) - or do my taxes get spent on some thing else?
