B744 lining up allowance for TORA

[GSLOC]

When calculating operational MTOW, lining up allowance should be subtracted from TORA. Unlike for other boeing aircraft, there is no mention of such allowance in FPPM.

Anyone knows what is the typical distance required for B744 to line up rwy from 90 and 180 degrees turn?

Don't know if it is official boeing data or company derived, but my manual says 90 degree angle 50 meters, after backtrack 75 meters any other angle 150 meters.

Thanx for reply! Is this from your company's SOP?


Has anyone also got the same numbers for B777-200 (200/200ER)?

I guess should be smth in between for B767 and B747...

Uhhh, wel it is in our manual, so that would make it our company's SOP. As stated, I don't know if it is official boeing data or company calculated!

These numbers can be found in the Boeing appendix to the Takeoff Safety Training Aid.
