(a) during the period of 28 consecutive days expiring at the end of the day on which the flight begins exceeds 100 hours; or
That would then mean that for each day off a further 100hr block would become effective. i.e. 125 flying hours within a CALENDER MONTH is OK, in regard to the ANO.
Eh?????
This is pretty basic english and unambiguous. If at any time your total exceeds 100 hours over the previous 28 days you are illegal. If you have 97 hours in the last 27 days and do four hours today then you will, at the end of today, have done 101 hours in the last 28 days and be illegal.
What difference does it make whether you flew yesterday or the day before or the day before that? If you did the 97 hours in 14 days, did nothing for the next 13 days and then four hours on the 28th day you would still be illegal.
