Dear Members,
If the required Non stopping & stopping headway can be achieved by 3 aspect signals means, the the same Non stopping & stopping headway can be achieved by 4 aspect signals also.
During headway calculation, normally I start with 3 aspect, when it is fail to meet the required headway then attempt with 4 aspect.
During examination, shall I attempt my calculation directly to 4 aspect instead of initially attempting with 3 aspect ?
I feel it save exam time and also avoid critical situation like transition required from 3 to 4 aspect to meet the operating requirements.
My question fully focus exam point of view. Attempting this method leads to any negative feedback like reducing marks ?
Kindly clarify and if I am wrong kindly correct. Thanks in advance

NJK
