Hello
I am studying towards an exam (Performance and Flight Planning) which refers to CAP698 from UK's CAA.
I am have some uncertainty as to how to the Regulatory Factor for calculating the Take Off Distance REQUIRED.
In CAP698 they apply in the example a Regulatory Factor of 1.15 to the take off distance required for the MEP1 Aircraft (see Page 2 Section 3) because it is an Unbalanced field.
In the case of SEP1 Aircraft (see Page 2 Section 2) in the example they do not mention that it is an unbalanced field and do not apply that Regulatory factor of 1.15. So if it is balanced, I think they should then multiply the result by 1.25 (no stopway of clearway)...? I am confused
There is no place where this nuance is explicitly explained. So can someone clarify to my when to use the 1.15 (TODA) factor, when to use the 1.3 (ASDA) and the 1.25 (TORA) when it comes to applying factors to the TOD from the graph?
Here is CAP698 online:

Thank you in advance!
