However, wrt to the 100hr flying limit within 28 days, it makes reference to 'the aggregate of all previous flight times'... and yet seemingly nowhere is the term 'flight times' defined.
Flight time is defined as:-
#‘Flight Time – Aeroplane’ means the total time from the moment an aeroplane first moves for the purpose of taking-off until the moment it finally comes to rest at the end of the flight.
Ref CAR Part I Section 1-11.
Under CAR 1.1 General definitions.
FTL's are in CAR Part IV Section 1 subpart Q.
So your 900 and 100 are block to block.(Flight Time)
