View Full Version : B737 Efis - TO Shift

7th Mar 2008, 13:19
Hello everybody,

I have a question for you, sure you'll be able to help me. I don't remember how to insert the take off shift in the TAKE OFF REF PAGE of the FMC. In our FMS version, there is TO SHIFT - Rw xx -00m, but I can't remember how you can change it.

Thanks for your help!

Just type a number into the scratchpad and line-select it to the line on which the T/O shift has to be entered?!

Depends on your FMC software whether for e.g. 400 metres you only need to enter the "4"', since the "00" seem to be in place already, or whether you have to type 400. Just try it during your next flight ground operations - you can always delete the figure again, or enter a displacement of 0.
Anyway, the distance to be entered is "down the runway", so (+) 400 metres will mean that your actual runway available is 400 m shorter than full length. The FMC only uses this info for a better update of position when you initiate the take-off (it does not change FMC calculated take-off speeds). The distance down the runway can be determined from your airport chart, if necessary, together with the "available distance" signs that should be provided at RW intersection points.
