MRJT Climb.......straight forward extraction of data from the table:

ISA -10....CAP697 page 41.

FL280 row.....58000kg column.....13 minutes (no need to interpolate for 57500kg....makes no difference)

The distance you get from the table is NAM. If you want to find the ground distance you apply the formula given on the previous page ...

NGM = NAM x (GS/TAS) (simply plug in the TABULATED figures)

What you can't do is apply the 'distance = speed x time' formula to the tabulated data ... this is because this data includes actual take-off ... that initial acceleration down the runway, and this distorts the data.

Page numbers - the exam system is now working with CAP697 Second Edition - if you signed up recently, this is the version you will have - however, quite a few are working with the original version (seems to be about 50-50 at the moment on the brush up course). Page numbers reflect the original ..... just use the TABLE or FIG references .... this is what you will get in the exam anyway!
